An agent sends a Business Transaction: who authorized it, what action it wants, and the facts that justify it. Parmana evaluates the policy bound to the action, checks any signed human approval the policy requires, releases the action to the connector only if the policy approves, and returns a signed Execution Trust Record anyone can verify. **Authentication.** Send `Authorization: Bearer ` on every request. The only routes that need no key are the probes, the documents and the independent verification routes: `GET /health`, `GET /ready`, `GET /openapi.yaml`, `GET /openapi.json`, `GET /api-manifest.json`, `GET /documentation`, `GET /reference`, `GET /parmana-handbook.pdf`, `GET /handbook/download-leads`, `POST /handbook/download-leads`, `POST /refusal/verify`, `POST /execution-intents/verify`, `POST /audit/verify`, `GET /keys/{keyId}` and `GET /.well-known/jwks.json`. A missing or unknown key returns `401` before anything else runs. The server holds only a hash of each key. See [Authentication](/api-reference/authentication). **Two kinds of key.** An agent or service key may invoke only the capabilities listed on it. A human key (`credentialHolderType: USER`) is required for governance: proposing and approving policies, approvers and external connectors, and repairing Execution Intents. Approving or rejecting a change also needs a step up authorization signed with the checker's own step up key, and the checker must not be the person who proposed it. **Ownership.** Every lookup by `businessTransactionId` is scoped to the key that submitted the transaction. A transaction submitted by another key returns the same `404` as one that does not exist. **Try it live.** The first server below is the public sandbox, `https://parmana-sandbox.vercel.app`: the same code as production with its own database, keys and demo approver, whose one action, `sandbox:receipt`, acts on nothing. Every "Try it" panel calls it with the published demo key prefilled. The demo key may invoke only `sandbox:receipt`, so other capabilities return `403` and governance routes return `403 NON_HUMAN_CALLER_DENIED`. Everything sent to the sandbox is visible to every visitor. See [Playground](/playground). Production needs a key issued by its operator. **Start here:** the [Playground](/playground) (no install), the [Quickstart](/quickstart), then [Integrate Parmana](/agents/integrate) for agents and [Connect any external system](/guides/connect-any-external-system) for your own endpoint. contact: name: Parmana Systems email: founder@parmanasystems.com license: name: Proprietary, source-available for evaluation only, see LICENSE url: https://github.com/pavancharak/parmana/blob/main/LICENSE servers: - url: https://parmana-sandbox.vercel.app description: >- Public sandbox (the docs playground).

Nothing changes until a different person approves it. You may not propose authority for your own key. Under a policy with `requireAuthorityGrant`, a request from a key with no grant in force, or outside its limits, is refused as `NOT_AUTHORIZED`, and one after `validUntil` as `AUTHORITY_EXPIRED`. To change a grant, revoke it, then grant again.
