# Publish a policy

POST

/v1/policies

```sh
curl --request POST \
  --url https://example.com/v1/policies \
  --header 'Authorization: Bearer <token>' \
  --header 'Content-Type: application/json' \
  --data '{ "id": "example", "tenantId": "2489E9AD-2EE2-8E00-8EC9-32D5F69181C0", "version": "example", "kind": "access-control", "description": "example", "spec": {} }'
```

Body is a full `Policy` — the server validates top-level shape (id, tenantId, semver version, kind ∈ closed enum, spec is an object), and `spec` for `tool-errors`, `hitl` and `retention` (a retention policy with an unknown domain or `mode: archive` is refused with `400 validation-failed`, naming the field). Other kinds’ specs are their runtime consumer’s to validate. Re-publishing an existing `(policyId, version)` returns `409 policy-already-registered`. A tenant has one retention policy per domain, plus one for `*`: a second policy id for a covered domain is refused with `409 policy-scope-taken` (`details.heldBy` names the policy that covers it; publish a new version of that one instead), and a new version can’t move a policy to another domain (`409 policy-scope-changed`). A known kind that no runtime consumer applies yet (`access-control`, `adapter-allowlist`, `rate-limit`, `compliance`) is refused with `400 kind-not-applied` (`details.appliedKinds` lists the ones that are): publishing it would change nothing. Idempotency-Key applies (retries with the same key replay the original 201).

## Authorizations

- **[bearerAuth](https://docs.kindgi.com/v0.1.8/reference/api.md#bearerauth)**

## Parameters

### Header Parameters

**Idempotency-Key**

string

\>= 1 characters

Caller-supplied idempotency key, scoped to the caller: the same key from someone else in the tenant is their own request (from 0.1.5). Retries with the same key return the original response byte-identical (per `docs/API-ROUTE-CONVENTIONS.md` §3.1). A retry sent while the first request still runs is answered `409 idempotency-key-in-flight` with `Retry-After`, on a runtime whose store holds keys (from 0.1.5); retry after it, and you get the first request’s answer. An answer that carries a secret (a new API key or public run token, a session token, a generated signing secret) isn’t kept: a retry gets `409 idempotency-key-replay-withheld`, with the first request’s status and when it succeeded (from 0.1.5).
