Works on both the authenticated and (where enabled) anonymous public surface. ## OpenAPI ````yaml POST /v1/intelligence/evaluations/validate openapi: 3.1.0 info: title: Anton Payments API version: 1.0.0 summary: Cross-border payout infrastructure. Fiat, stablecoin, and crypto. description: > The Anton Payments merchant API. Versioned, idempotent, cursor-paginated. - **Authentication**: OAuth 2.0 client_credentials with DPoP proof-of-possession (RFC 6749 §4.4 + RFC 9449). Programmatic clients exchange `(client_id, client_secret)` for a short-lived access token at `POST /oauth/token`, then send each request with `Authorization: DPoP ` plus a per-request `DPoP: ` header. Static API keys are not accepted on v1. - Base URLs: `https://api.antonpayments.com` (production), `https://api.antonpayments.dev` (sandbox). - Monetary amounts are decimal strings. Never floats. - Timestamps are RFC 3339 UTC. - All mutating endpoints support the `Idempotency-Key` header. - Anton's OAuth public signing key is published at `GET /.well-known/jwks.json` (5-minute cache; RFC 8615). **Capabilities and scopes.** Every account carries a capability set (`payouts`, `intelligence`) and every credential carries a scope set validated against it at creation. AI-compliance-only accounts hold only `intelligence` — all payout-surface endpoints return `403 capability_required` for them. A credential minted without a scope returns `403 insufficient_scope` on that surface. Effective access is `scopes ∩ capabilities`. Access tokens embed the grants as a space-delimited `scope` claim, echoed in the token response. See the Cross-Cutting section of the docs for idempotency, pagination, rate limits, errors, webhook events, and webhook signing. contact: name: Anton Payments Support url: https://help.antonpayments.com license: name: Proprietary url: https://www.antonpayments.com servers: - url: https://api.antonpayments.com description: Production - url: https://api.antonpayments.dev description: Sandbox security: - oauthDPoP: [] dpopHeader: [] tags: - name: Authentication description: >- OAuth 2.0 token endpoint and JWKS publication.

Register a credential via the merchant portal. Anton issues a `client_id` (`ant_oc__<32hex>`) and a `client_secret` (`ant_ocs__<48hex>`, shown ONCE). The portal generates an ES256 or Ed25519 DPoP keypair in your browser; you store the private half. 2. Mint an access token: `POST /oauth/token` with `Authorization: Basic ` and `Content-Type: application/x-www-form-urlencoded`. Body: `grant_type=client_credentials`. A `DPoP` header carrying a proof signed for the token endpoint is required (no `ath` claim on this proof). 3. Use the token: send `Authorization: DPoP ` plus a fresh `DPoP: ` header on every `/v1` request. The proof JWT MUST carry `htm` (request method), `htu` (request URL, no query/fragment), `iat` (within ±60s), `jti` (unique within 5 min), and `ath` (SHA-256 of the access token, base64url). Tokens expire in **1 hour** in production / staging and **8 hours** in sandbox. There are no refresh tokens — call `/oauth/token` again with your secret. Anton's public signing key is published at `/.well-known/jwks.json`. OpenAPI 3.0 has no native DPoP scheme; this declaration plus `dpopHeader` together convey both the access-token Authorization and the per-request proof header. flows: clientCredentials: tokenUrl: /oauth/token scopes: payouts: >- Money movement — payouts, batches, beneficiaries, instruments, balances, funding, FX. intelligence: Anton Intelligence — screening evaluations and evidence. dpopHeader: type: apiKey in: header name: DPoP description: > Per-request DPoP proof JWT (RFC 9449). MUST accompany the `Authorization: DPoP ` header on every protected operation. The proof is signed by the merchant's private DPoP key and carries `htm`, `htu`, `iat`, `jti`, and `ath` claims. ````
