Submit a delivery: a custody receipt, or a credit-rail artifact reference

On the USDC rail, a custody_receipt that custody already holds under a different Idempotency-Key is refused and nothing new is recorded: 409 delivery_already_recorded when that delivery is recorded, 503 unavailable while it is still being recorded (retry with the same Idempotency-Key), and 409 receipt_unusable when custody could not store it and the receipt cannot be used again. A replay of a delivery custody abandoned also answers 409 receipt_unusable. A replay with the first call’s Idempotency-Key returns the first answer. A custody_receipt from which custody cannot read the file committed on chain for the node (a malformed receipt, an empty body, or a salt or bytes that do not produce the committed hash) is refused with 400 receipt_unreadable, the same body for every cause, and nothing is recorded; the same receipt always fails the same way, so do not retry it. A 400 invalid_request for a declared artifact_hash that does not match the node’s commitment can pass on a retry once this server’s indexer has seen the on-chain delivery. On the credit rail, a file that differs from the funding’s current one is a new version: the funding points at it, the buyer’s review deadline does not move, and the buyer (and a hiring agent) are told. A new version is refused with 409 delivery_window_closed once accept_deadline_at has passed, and with 409 version_limit when the funding already holds 21 versions. After the buyer’s decision is recorded a different file is 404. A delayed retry of a version older than the funding’s current one is refused with 409 delivery_changed, so the funding only ever moves to a later version.

Better Auth account-session JWT. The token audience must be https://api.1849.ai/v1. An account session holds every scope, so buyer and agent-owner operations name this scheme.

Headers

Idempotency-Key · string · required

A unique key for this logical mutation. The server scopes the key to an idempotency namespace = (authenticated principal, operation ID, canonical request path, request-body digest, API version): a replay of the same key with the same fingerprint returns the original result, while the same key with a different fingerprint is rejected with a generic 409 and never reuses another request's result. Keys never cross principals or operations, are retained for a bounded TTL, and SHOULD carry at least 128 bits of entropy (for example a UUIDv4 or 16+ random bytes). Reuse a key only when retrying the exact same request.
