A READY job transitions to DELIVERED on first download (stamping `downloadedAt` / `downloadedBy`); a DELIVERED job serves the same artifact idempotently — no state change, no duplicate event. The response carries a deterministic `content-disposition` attachment header (`enfinitos-dsar-export-.json`) and `cache-control: no-store`. Expiry is enforced lazily: a READY job whose `delivery.expiresAt` has passed is swept to EXPIRED before the refusal. EXPIRED (and every other non-READY/DELIVERED state) returns 409; a READY/DELIVERED job whose artifact is no longer in the store returns 412 (re-run regenerates an identical bundle — the builder is deterministic). Requires scope `audit:read`. ## OpenAPI ````yaml /openapi-v1.yaml get /v1/compliance/dsar/{jobId}/download 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_…`. All timestamps are ISO-8601 strings. contact: name: EnfinitOS Developer Support url: https://docs.enfinitos.com email: developers@enfinitos.com servers: - url: https://sandbox.api.enfinitos.com description: Sandbox — live today - url: https://api.enfinitos.com description: Production — at the April 2027 launch security: - bearerAuth: [] tags: - name: Discovery description: Unauthenticated contract + health probes. - name: Tenant description: Read the caller's sandbox tenant snapshot. - name: Rights description: Bases and the right lifecycle (issue, suspend, resume, revoke). - name: Offers description: Propose, accept, reject, counter, and withdraw offers. - name: Challenges description: Open, resolve, and withdraw challenges against rights. - name: Delivery description: Observe constraint-gated delivery events. - name: Audit description: The append-only event log. - name: Proof description: Signed proof packs. - name: Metering & Settlement description: Metering and settlement projections. - name: Settlement config description: Settlement rules and counterparties. - name: Compliance description: GDPR Article 15 export and Article 17 erasure. - name: Webhooks description: Webhook subscriptions and delivery history. - name: Disputes description: Delivery disputes — open, investigate, respond, resolve. paths: /v1/compliance/dsar/{jobId}/download: get: tags: - Compliance summary: Download a DSAR export description: >- Serve the materialised export artifact.
