Cards are created DRAFT by default; activation is a separate, explicit step (a card moves real money exactly like a settlement rule does) — pass `activateOnCreate: true` to go straight to ACTIVE, or SCHEDULED when `activeFrom` is in the future. One price per unit type per card. Requires scope `settlement:write`. ## OpenAPI ````yaml /openapi-v1.yaml post /v1/rate-cards openapi: 3.1.0 info: title: EnfinitOS API version: v1.0 description: >- The governed-execution `/v1` developer API for EnfinitOS — rights, delivery, proof, and settlement. Use this API to register the legal **bases** a right rests on, **issue** and lifecycle-manage rights across delivery substrates (DOOH, CTV, spatial/AR, mobile, audio, and more), negotiate **offers**, raise and resolve **challenges**, observe constraint-gated **deliveries**, seal signed **proof packs**, read **metering** + **settlement** projections, configure settlement **rules** and **counterparties**, fulfil GDPR **compliance** requests, and subscribe to **webhooks**. Every state-changing action is appended to an immutable, signable audit log; delivery and proof artefacts are Ed25519-signed so a downstream auditor can verify them offline. ## Response envelope Every response wraps its payload in a canonical envelope. Success (HTTP 200): ```json { "ok": true, "data": { ... }, "contractVersion": "v1.0" } ``` Error (4xx / 5xx): ```json { "ok": false, "error": "VALIDATION_FAILED", "message": "human text", "contractVersion": "v1.0" } ``` Some error responses carry additional context fields alongside `error` and `message` (for example `field`, `validationErrors`, `requiredScopes`, `keyScopes`). ## Authentication All endpoints except `GET /v1` and `GET /v1/healthz` require an API key sent as `Authorization: Bearer `. Keys carry a set of named scopes; each operation documents the scope it requires. A key carrying the `*` wildcard scope passes every scope check. Pre-launch, sandbox keys are issued through the apply flow: request access at `/apply`, receive an activation email on approval, and exchange it for a `/v1` sandbox key in the integration playground at `/developers/playground`. Self-service key issuance from the developer dashboard at `/developers/dashboard` lands at the April 2027 production launch. ## Identifiers Resource ids are prefixed: bases `bas_…`, rights `rgh_…`, offers `ofr_…` (passed as `rightId`/`offerId`), settlement rules `rule_…`, counterparties `cp_…`, webhook subscriptions, and webhook deliveries `dlv_…`.
