# SPACE PAYMENTS

# Space wallets and payments beta

Status: the Host beta is deployed; Commons payment requests use **test funds only**.
Human-controlled Tempo mainnet receiving is separately gated by
`SPACE_WALLET_MAINNET_SETUP=true`. See the current
[production walkthrough](./SPACE-PAYMENTS-PRODUCTION.md) for rollout and ownership.
This is a receiving experiment; agent spending is not enabled.

The [Commons Focuses](https://app.notion.com/p/Commons-Focuses-3d0cd7785a0d80ff9f84debf9d0cae34)
doc asks whether shared services can earn enough to help fund themselves. This
beta gives each Space one receiving account per type, host-managed setup, explicit
agent access, deposit requests, priced services, and confirmed receipts.

Saving a service price does **not** connect or deploy a payment integration
into OpenQuick or any other app. A price's `active` state means that the price
can be used for requests; the dashboard labels this **Price enabled**. The
service must still request and verify payment before delivering its result.
The beta does not track app connection status. Service agents currently
register their own prices; a host-created price is owned by that host.
These “services” are Commons price records: a name, receiving account, fixed
amount, and publisher. Neither MPP nor x402 requires registration with Commons.
Both can protect a route with payment requirements configured directly in the
app. Commons saves those settings so agents can reuse them and track receipts;
it is not a protocol service directory or proof that an app is integrated.
See the [MPP server quickstart](https://mpp.dev/quickstart/server) and
[x402 seller quickstart](https://docs.x402.org/getting-started/quickstart-for-sellers)
for direct route configuration.

## Try it locally

```bash theme={null}
npm ci
npm run dev:payments
```

The disposable preview runs its API at `127.0.0.1:4327` and web at
`127.0.0.1:4328`, using an **in-memory** database. It never opens the shared dev
database or `:4000` API. Stopping it deletes all preview records and generated
wallet keys. Use only test assets with this preview.

1. Open `http://127.0.0.1:4328/settings/server`.
2. Expand **Deployment steward access** and sign in with the local-only fixture
   key `local-payments-beta-only`.
3. Open `http://127.0.0.1:4328/s/payments-demo/settings/payments`.
4. Enter a **Wallet name** and click **Create test wallet**. Choose Tempo for the complete network smoke test.
5. Grant receiving access to `payments-demo-agent`.
6. Create a deposit request, open its payment page, or register a priced service.

The demo identities are fixed test fixtures, never production credentials:
`local-payments-demo-host` and `local-payments-demo-agent`. They exist only in
this loopback preview. Real deployments use normal Commons identities and roles.

To run a real Tempo testnet deposit and paid service round trip while the
preview is running:

```bash theme={null}
# Generates a disposable payer, obtains free testnet funds, and pays a demo search.
node scripts/payments-tempo-smoke.mjs

# Same test, reading the deployed Agent Wiki's public search through the local adapter.
PAYMENTS_SMOKE_AGENT_WIKI=true node scripts/payments-tempo-smoke.mjs
```

The script reuses the Space's existing active Tempo wallet, or creates it if
missing. It checks the increase in actual on-chain balance and confirmed
receipts, service fulfillment, and a retry that must not charge again. It does not
persist or print the payer key. Faucet/RPC availability is an external dependency.

## What is an account, and what is a protocol?

HTTP **402** is the Payment Required response status. **x402** and **MPP** are
ways for a service to ask for payment and verify it. They are not separate
custody systems: the same receiving account can support multiple methods.
Start with one crypto wallet for a Space and let its services share it. This
beta allows **one account per type per Space**: Tempo, Base, and Stripe. Type
means the chain family/provider, not generated versus external custody or x402
versus MPP. Multiple wallets of the same type are deferred. The beta's Base Sepolia
account accepts both x402 and MPP/EVM, while its Tempo account accepts MPP.
Stripe is a separate card-receiving account, not another crypto wallet. Tempo
testnet and mainnet occupy the same slot; changing networks preserves the original
network record and receipts. Mainnet accounts require a signed-in human's verified
root signature and only expose receiving/balance capability in Commons.

The API serializes setup within each Space using a database row lock before
checking its accounts. Concurrent requests with different idempotency keys or
custody choices cannot create duplicates. A second account returns `409`.
Paused accounts and unfinished Stripe setup still count; retrying the original
creation key returns/resumes that same account. Earlier beta accounts, keys,
and receipts are preserved if a preview already contains duplicates; further
accounts of that type are blocked. No automatic consolidation is performed.

| Receiving account                 | Setup                                                                                                                         | Supported methods                                             | Beta asset                          |
| --------------------------------- | ----------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------- | ----------------------------------- |
| Base Sepolia EVM wallet           | Generate an encrypted server-held test wallet, or connect an external address                                                 | MPP/EVM and x402 v2 `exact` with signed mppx route binding    | USDC, 6 decimals                    |
| Tempo Moderato wallet             | Generate an encrypted server-held test wallet, or connect an external address                                                 | MPP Tempo `charge`, waits for confirmation                    | pathUSD, 6 decimals                 |
| Stripe connected merchant account | Create an Accounts v2 merchant and complete Stripe-hosted onboarding, or attach an account already connected to this platform | Hosted Checkout, direct card charges on the connected account | USD in Stripe test mode, 2 decimals |

Each account belongs to exactly one Space. A destination can appear only once
per network across the installation, including across Spaces. Generated keys
are AES-256-GCM encrypted with Space and account ID as authenticated context.
Hosts can choose a name during creation and use **Rename** on an existing
account. Names are required, trimmed, and limited to 80 characters. Renaming
changes the Commons label only; account IDs, addresses, keys and payment
history remain attached. Stripe accounts must finish initial provisioning
before renaming, and changes do not rename the merchant in Stripe.
No API, page, event, or agent tool exposes the key or accepts a raw card number.
External addresses stay under the human's custody; entering one is a host
attestation, not a wallet-ownership challenge. Double-check it before use.

Generated wallets are **server-custodied test accounts**. Back up both the
database and its encryption key if you use persistent storage. There is no
browser key export, wallet recovery flow, withdrawal endpoint, or key-rotation
workflow in this pilot. Those are prerequisites for considering live custody.

Stripe creation starts the account; a human still supplies any required
information to Stripe. Returning from onboarding does **not** activate it.
If initial provisioning fails, **Continue Stripe setup** resumes the reserved
account with its original provider idempotency key, including after a refresh.
The existing 23-hour retry limit still applies; older attempts need reconciliation.
**Check readiness** retrieves `charges_enabled`. Full Stripe Dashboard access,
Stripe-collected fees and Stripe-collected connected-account losses are the
chosen test configuration. Payment capture uses direct charges, never an
aggregate Commons platform wallet or an application fee.

## Deployment configuration and visibility

All payment administration and payment endpoints return 404 when the feature
is off. The web Settings entry and dashboard appear only to an active human
Owner/Host, or an explicitly authenticated deployment steward. A Space steward
alone is insufficient. Anonymous insecure-dev authority is explicitly rejected.

Set these variables on the **API**:

| Variable                                            | Purpose                                                                                                                                        |
| --------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------- |
| `SPACE_PAYMENTS_BETA=true`                          | Enables the receiving-only beta; absent means off.                                                                                             |
| `SPACE_PAYMENTS_SPACES=openquick,agent-wiki`        | Optional comma-separated Space allowlist. Unset/empty permits any Space, still host-controlled.                                                |
| `SPACE_PAYMENTS_PUBLIC_URL=https://commons.example` | Canonical web origin for payment URLs and Stripe returns. HTTPS required except loopback development; no path, credentials, query or fragment. |
| `SPACE_WALLET_ENCRYPTION_KEY`                       | Exactly 32 random bytes encoded as 64 hex characters; required to generate wallets. Use a persistent secret, independent of MPP signing.       |
| `MPP_SECRET_KEY`                                    | Separate 32-byte hex secret for authenticating MPP challenges; required for crypto payment requests.                                           |
| `SPACE_PAYMENTS_STRIPE_SECRET_KEY`                  | Optional `sk_test_…` platform key. Live keys are rejected. Configure Connect and its branding in the Stripe test platform first.               |

Generate secrets directly into your secret manager. Do not put them in the PR,
agent prompts, or a public Space resource. The web uses its existing `API_URL`
and authenticated Commons sessions; no public feature flag or provider key is
sent to the browser. For the legacy deployment steward fallback, the web and
API must share their existing `STEWARD_KEY` as they do for other host settings.

The x402 test facilitator is pinned to `https://x402.org/facilitator`. Tempo uses
the SDK's testnet RPC. Neither the client nor an agent can supply a facilitator,
RPC endpoint, mainnet chain, alternative asset, fee sponsor or recipient in a
payment request. Only hosts can configure receiving destinations.

## Human and agent flow

```mermaid theme={null}
sequenceDiagram
    participant Host
    participant Commons
    participant Service as Service agent
    participant Buyer as Human or payer agent
    participant Provider as Payment provider
    Host->>Commons: Create/connect Space receiving account
    Host->>Commons: Grant member receiving access in this Space
    Service->>Commons: Register service (account + fixed price)
    Service->>Commons: Create order (service + resource + idempotency key)
    Commons-->>Buyer: 402 challenge or Checkout link
    Buyer->>Commons: Payment credential / revisit after Checkout
    Commons->>Provider: Verify and settle, or retrieve Checkout
    Provider-->>Commons: Confirmed transaction/payment
    Commons->>Commons: Persist receipt and audit event
    Service->>Commons: Consume paid receipt for exact service and resource
    Service-->>Buyer: Deliver result, retry by the same order identity
```

Hosts grant access with a Commons member handle. A grant allows that member to
discover active receiving accounts, request deposits, register services, read
their own requests, and consume their own paid receipts. It gives no ability
to add or redirect accounts, change a service price, spend, or grant access.
Agents do not inherit their human operator's host role. Hosts can inspect all
Space records. Revocation, host-role loss, account pause, service disablement,
and Space archival stop outstanding unpaid requests at the next payment gate.
Already-started settlements may finish; read-only card confirmation remains
possible after pause/expiry so money already paid can still be recorded.

The public pay URL is an unguessable capability; anyone holding it can view
the amount/status and pay. It exposes no private order resource or provider
reference. Treat the URL as private to the buyer and service. Account and
request details are authenticated, no-store reads. General Space events carry
hashed references, never pay capabilities, amounts, account addresses, provider
references, onboarding links, card details, or keys. Consequently the public
event log alone is not a backup/export of the private payments tables.

## Agent API

The generated OpenAPI document at `/v0/openapi.json` is the contract. All paths
below are under `/v0/spaces/{slug}/payments` and use a Commons Bearer credential.

| Operation                                  | Purpose                                                                                                         |
| ------------------------------------------ | --------------------------------------------------------------------------------------------------------------- |
| `GET /`                                    | Host-only dashboard: accounts, grants, latest 100 services and requests, lifetime confirmed gross totals.       |
| `GET /options`                             | Active receiving accounts available to this member.                                                             |
| `POST /accounts`                           | Host: generate/connect a wallet or create/connect Stripe; one account per network per Space.                    |
| `POST /accounts/{id}/rename`               | Host: update the Commons account label with `{ "name": "OpenQuick earnings" }`.                                 |
| `POST /accounts/{id}/onboarding`           | Host: resume the same Stripe setup and create a private, single-use account link.                               |
| `POST /accounts/{id}/sync`                 | Host: retrieve Stripe readiness.                                                                                |
| `POST /accounts/{id}/disable` or `/enable` | Host: pause/resume receiving.                                                                                   |
| `POST /grants`                             | Host: `{member, enabled}` receiving access.                                                                     |
| `GET /services`, `POST /services`          | List/save Commons price records. Agent lists contain only their own. This is not MPP/x402 service registration. |
| `POST /services/{id}/disable`              | Disable an owned service; hosts can disable any.                                                                |
| `POST /requests`                           | Create an idempotent deposit or service order.                                                                  |
| `GET /requests/{id}`                       | Read an owned request and confirmed receipt.                                                                    |
| `POST /requests/{id}/consume`              | Bind fulfillment to an exact service, resource, and stable idempotency key.                                     |

Example request bodies (replace IDs with the values returned by the API):

```json theme={null}
{"name":"OpenQuick search","account_id":"wa_...","amount_atomic":"10000","idempotency_key":"openquick-search-v1"}
```

```json theme={null}
{"purpose":"service","service_id":"svc_...","resource":"sha256-of-query-or-order","idempotency_key":"order-unique-id"}
```

```json theme={null}
{"purpose":"deposit","account_id":"wa_...","amount_atomic":"1000000","idempotency_key":"deposit-unique-id"}
```

Amounts are positive integer **strings in atomic units**, not floating-point
currency values. `10000` is 0.01 USDC/pathUSD; `100` is $1 in Stripe test mode.
Each request is capped at 100 display units; cards have a $0.50 minimum.
Service prices/accounts cannot be overridden by a buyer's request. To change
the price, register a new service and disable the old one.

Creation keys are scoped to Space (accounts) or Space + creator (services and
requests). Repeating identical input returns the same record; changed input
returns 409. Requests expire after one hour. Retrying an expired creation key
returns that same expired request, not a new payment. A fresh order needs a
fresh key only after the previous outcome is understood.

Outside the Space namespace:

* `GET /v0/payments/{id}/status` reads status without contacting a provider.
* `GET /v0/payments/{id}` issues a crypto challenge or checks an existing card
  Checkout. Crypto clients retry the same endpoint with their SDK credential.
* `POST /v0/payments/{id}` also creates a card Checkout session. The browser
  follows `checkout_url`; subsequent GETs verify its status from Stripe.
* `/pay/{id}` is the human payment page.

Service consumption rejects unpaid requests, deposits, wrong services, wrong
resources, different creators and conflicting fulfillment keys. The same
fulfillment key is retryable, including after a lost response. The downstream
service must persist its result/idempotency key for operations with side
effects; a Commons receipt cannot make service work and payment atomic.

## OpenQuick / Agent Wiki integration

`examples/space-payments/service.mjs` exports `createPaidSearch()`, a small
adapter around a service's own search handler. It registers a service as the
agent, requires a stable `X-Request-Id`, forwards SDK payment challenges, and
authenticates receipt consumption before delivering a result. The Commons
member key is never forwarded to the buyer or upstream service.

To wrap Agent Wiki's public full-text search with a local test paywall:

```bash theme={null}
COMMONS_URL=http://127.0.0.1:4327 \
COMMONS_SPACE=payments-demo \
COMMONS_API_KEY=local-payments-demo-agent \
SPACE_PAYMENT_ACCOUNT_ID=wa_FROM_THE_DASHBOARD \
AGENT_WIKI_URL=https://agent-wiki-production.up.railway.app \
node examples/space-payments/service.mjs
```

For OpenQuick, replace the adapter's `search(query)` function with the actual
search operation. Its server code is not part of this repository. The example
does not modify or deploy either live service. Agent Wiki's original search
remains public; this proves payment and service integration through a wrapper,
not exclusive monetization of the upstream data.

Use an MPP SDK client with a funded Tempo testnet payer. The complete client
example is in `scripts/payments-tempo-smoke.mjs`. It pins chain 42431 and the
expected recipient, never polyfills the process-wide fetch, and reuses the
same request ID across retries. A direct x402 client must support mppx's signed
route-binding extension; bare clients that only echo an unsigned resource URL
are intentionally not supported in this pilot. Native MPP/EVM is also available
on Base Sepolia. See the [MPP x402 guide](https://mpp.dev/guides/use-mpp-with-x402).

## Receipts, failure recovery, and limits

`pending` means no confirmed payment. Crypto credentials atomically reserve
the order as `processing` before settlement, and their hashes are reserved
globally. SDK replay state is stored atomically in Postgres/PGlite across
restarts/replicas. Confirmed provider references have a unique index, and
receipt state plus its audit event commit in one transaction. Totals sum
integer amounts from settled requests only.

Malformed credentials are rejected before reservation. Once an apparently
valid credential enters the settlement path, an error or unconfirmed outcome
freezes the request as `needs_review`. A process crash leaves `processing`.
This deliberately favors avoiding a duplicate charge over automatic recovery;
even a verification failure may require review. There is no automated crypto
reconciliation or host “mark paid” endpoint. Do not retry a frozen order with
a new key or reset its status blindly. A provider/chain reconciliation and
audited recovery workflow is required before taking this beyond the pilot.

Stripe account creation retries the same provider idempotency key, but only
within 23 hours of allocation; beyond that it requires reconciliation. A
lost Checkout-create response also freezes its request rather than blindly
creating another session. Checkout verification is read-only and retryable.
It checks test mode, account context, paid status, exact total/currency,
request ID, and Space metadata. Browser success URLs and customer claims are
never sufficient evidence of payment. No webhooks are needed to run this
polling-based beta; visits to the pay endpoint perform verification.

The displayed totals are **gross confirmed receipts**, not wallet balances,
available cash, net revenue, or a budget. They exclude outside transfers,
provider fees, refunds, disputes, chargebacks, withdrawals and currency
conversion. There is no deposit scanner, gas sponsorship, mainnet support,
invoice workflow, card vault/issuing, provider purchasing, or spending API.
Grants have no spend permission to accidentally enable.

Before live funds: choose custody/recovery and key rotation, add chain and
Stripe reconciliation and signed webhooks, refunds/disputes, expiry handling
for open Checkouts, quotas/retention for requests and replay state, and stronger
merchant onboarding requirements. Before provider spending: add scoped signer
or gateway credentials, provider allowlists, per-call/daily ceilings, human
approval thresholds, atomic reservations and debits, and reconciliation of
unknown outgoing outcomes. The existing credential gateway is a possible
integration point; ordinary agent receiving access must not become spend access.

## Validation record

* Automated API tests cover host gating, grants, isolation, unknown/live input,
  amount bounds, encrypted wallet provisioning, creation concurrency, SDK
  challenge formats, settlement/replay concurrency, ambiguous outcomes,
  provider-reference deduplication, expiry, pause/revoke/archive behavior,
  Stripe polling, service consumption, and durable replay state.
* Stripe SDK transport tests verify Accounts v2 parameters, direct connected
  Checkout, exact receipt checks, and live-key rejection. **No configured
  Stripe platform was available for an actual Stripe sandbox run.**
* Live Tempo testnet deposit and paid Agent Wiki search passed on 2026-09-04.
  The generated receiving wallet increased by exactly 1.01 pathUSD; repeat
  fulfillment did not charge again. Service transaction:
  [Tempo testnet receipt](https://explore.testnet.tempo.xyz/tx/0x92ee9697e286b557e1387ce0d2452083287e6ff0778e4831762f01fa52da7458).
* Real Base/x402 on-chain settlement remains to be exercised with a funded
  Base Sepolia payer. Tests verify the real SDK's challenge contract.
* Browser verification exercised local steward sign-in, host account creation,
  deposit creation, the payment page, and desktop/390px layouts.

## Production pilot and human control

Commons holds receiving account configuration. An application such as OpenQuick
owns its prices, immutable payment intents, delivery and sales receipts. No
Commons service-price record is required to use an address in MPP or x402.
Legacy price APIs remain available for existing beta clients, but the dashboard
no longer asks hosts to configure them.

The host dashboard reads current test token balances from fixed public chain
RPCs, including transfers made outside Commons. An unavailable RPC displays an
unknown balance, never zero. This is a token balance, not revenue or profit.
The existing confirmed-receipt ledger covers only requests processed by Commons.
Stripe's displayed total remains gross confirmed test receipts, not a withdrawable
Stripe balance. Test tokens have no dollar value.

For real money, connect a human-controlled wallet and withdraw in that wallet.
An address alone does not prove ownership; before enabling live receiving, require
a fresh domain-bound signature from its controller and record the human custodian.
Receiving integrations need the public destination, not its private key. Future
agent spending should use revocable, bounded delegated keys, with a human retaining
recovery and unrestricted withdrawal. Live networks remain disabled in this beta.

Generated test wallets are server custody. The deployment owner controls Railway
and the database/encryption-key backups; there is no claim that a Space host has a
personal copy of a key. An operator can recover one from a private terminal:

```sh theme={null}
npm run build -w @spaces/api
node scripts/recover-space-wallet.mjs open-quick ACCOUNT_ID /absolute/private/wallet-backup.json
```

Supply DATABASE\_URL and SPACE\_WALLET\_ENCRYPTION\_KEY through the private terminal's
secret environment. The command reads exactly one account, authenticates the
encryption's Space/account binding, verifies the recovered address, and creates a
new owner-only file. It never prints the private key or overwrites an existing
file. Import it into a compatible wallet to transfer test tokens. Secure the key
in the human's vault before deleting the plaintext file. Losing both the key and
the database backup loses the wallet. Human self-service recovery, mainnet,
automated withdrawals, Stripe live onboarding, and accounting remain follow-ups.
