The API enables creation, execution, verification, replay, and auditing of Business Transactions through cryptographically verifiable Execution Trust Records. **Every route requires a caller bearer key**, except the liveness/readiness probes and documentation/verification routes that must be reachable with no credential: GET /health, GET /ready, GET /openapi.yaml, GET /documentation, GET /reference, POST /refusal/verify, POST /execution-intents/verify, POST /audit/verify, GET /keys/{keyId}, and GET /.well-known/jwks.json. Send `Authorization: Bearer ` on every other request. Keys are issued by `scripts/generate-api-key.ts` and configured server-side via `PARMANA_API_KEYS`; only a hash of each key is ever held by the server, verified in constant time. A missing or invalid credential returns 401 before a Business Transaction is even constructed, independent of Policy evaluation and gateway attestation, see `packages/api/src/middleware/caller-auth.ts` and [Authentication](/api-reference/authentication). Local development may set `PARMANA_AUTH_DISABLED=true` to skip this middleware entirely; that flag must never be set in a real deployment. contact: name: Parmana Systems email: founder@parmanasystems.com license: name: Proprietary, source-available for evaluation only, see LICENSE url: https://github.com/pavancharak/AgentLabsBuildathon/blob/main/LICENSE servers: - url: https://parmana-api-real.vercel.app description: >- Production (real, deployed instance -- the docs site playground uses this by default) - url: http://localhost:3000 description: Local (packages/api, PORT env var, default 3000) security: - bearerAuth: [] tags: - name: Execution description: >- Executes a Business Transaction through the complete Execution Trust pipeline - name: Transactions description: Business Transaction creation and retrieval - name: Verification description: Deterministic verification of an Execution Trust Record - name: Receipts description: Cryptographically signed Execution Trust Receipts - name: Trust Records description: Execution Trust Record retrieval - name: Replay description: Deterministic replay of a recorded Execution Trust Record - name: Policies description: Policy existence/readability check - name: Policy Governance description: Maker-checker proposal, listing, approval, and rejection of policy changes - name: Approvers description: Maker-checker for the keys trusted to sign approvals, without a deploy - name: Refusal Records description: >- Durable, signed evidence that a policy decision rejected a transaction (RFC-0021) - name: Execution Intents description: >- A signed statement, stored before an action is released, of exactly what is about to be released, plus the operator tools to find and repair a released action that has no signed Trust Record (ADR-0012) - name: Audit description: >- Signed caller-authentication audit events, independently third-party-verifiable - name: System description: Operational endpoints paths: /approval-issuers/changes: post: tags: - Approvers summary: Propose adding or revoking an approver key description: > Proposes adding an approver key (action add, with the approver Ed25519 public key) or revoking a key added this way (action revoke). Nothing changes until a different person approves the proposal. Requires a human credential. A key listed in the server code is refused (409): change those with a pull request. A key id that already exists, revoked or not, cannot be added again: rotate by adding a new key id, then revoking the old one. operationId: proposeApprovalIssuerChange requestBody: required: true content: application/json: schema: $ref: >- #/components/schemas/propose-approval-issuer-change-request.schema responses: '201': description: Proposed, PENDING_APPROVAL. content: application/json: schema: $ref: '#/components/schemas/approval-issuer-change.schema' examples: add: summary: Real captured response value: changeId: ba7c5827-5844-4069-94fc-9b438ef08f78 action: add approverId: manager-priya keyId: manager-priya-key-1 publicKeyPem: > -----BEGIN PUBLIC KEY----- MCowBQYDK2VwAyEAEDuWHf+bbRY7J/Mr0RVmAKYHH5CDijTWhdnISXWLD6Y= -----END PUBLIC KEY----- reason: Priya approves refunds for the West region from October. proposedBy: human-maker proposedAt: '2026-09-28T19:05:59.726Z' status: PENDING_APPROVAL revoke: summary: Real captured response value: changeId: 348e9b4c-61dc-4bef-8815-6d4488750111 action: revoke approverId: manager-priya keyId: manager-priya-key-1 reason: Priya moved to another team. proposedBy: human-maker proposedAt: '2026-09-28T19:05:59.750Z' status: PENDING_APPROVAL '400': description: >- action is not add or revoke; approverId or keyId does not match ^[A-Za-z0-9._-]{{1,128}}$; reason is missing or longer than 2000 characters; publicKeyPem is not an Ed25519 public key (add) or is present (revoke). content: application/json: schema: $ref: '#/components/schemas/error.schema' examples: badKey: summary: Real captured response value: error: >- publicKeyPem must be an Ed25519 public key in PEM, as made by scripts/generate-approver-key.ts.
