  title: KnoxCall Client Management Environments API
  version: '1.0'
  description: 'The KnoxCall Client Management API provides programmatic access to manage your API gateway

    resources including routes, secrets, clients, environments, webhooks, and API keys. ## Authentication


    All requests must include an OAuth 2.1 access token **or** a legacy API key. The

    recommended path for new integrations is the first-party SDKs, which mint, cache, and

    refresh OAuth tokens for you (start with `knoxcall login` on a developer machine, or

    `KNOXCALL_CLIENT_ID` / `KNOXCALL_CLIENT_SECRET` in CI). You can authenticate using any of:


    - **Authorization header (OAuth 2.1 bearer token — recommended)**: `Authorization: Bearer `

    - **Authorization header (legacy API key)**: `Authorization: Bearer tk_xxx_yyy`

    - **x-api-key header (legacy API key)**: `x-api-key: tk_xxx_yyy`


    OAuth 2.1 access tokens (`kc_` prefix) are minted at the root-host token endpoint

    `https://api.knoxcall.com/oauth/token` (not under `/v1`) using the `client_credentials`

    or `authorization_code` grant. See the `OAuth2` security scheme and the `/oauth/*`

    endpoints. Some resources that are managed exclusively through OAuth reject API-key auth

    with a `403 use_oauth` error. Long-lived API keys remain fully supported. They come in three types:

    - **Standard keys** (`tk_` prefix) are used on the production API (`api.knoxcall.com`). - **Test keys** (`tk_` prefix, type=test) are used on the sandbox API (`sandbox.knoxcall.com`). - **Enterprise Access Keys** (`AKE` prefix) follow the format `AKE[16chars]:[40chars]`. Using a test key on the production API (or vice versa) will return a `403 wrong_key_type` error. ## Request IDs


    Every response — success or error — includes an `X-Request-Id` response header (a UUID). Its value is identical to the `request_id` field in the response body (`meta.request_id`

    on success, `error.request_id` on error). Quote it when contacting support. ## API Versioning


    The API is versioned on two axes:


    - **Major version — the `/v1` path prefix.** Breaking changes ship under a new major

    (`/v2`). `/v1` never receives a breaking change. - **Minor version — the `KnoxCall-Version` header (dated, `YYYY-MM-DD`).** Send

    `KnoxCall-Version: 2026-08-05` to pin the behaviour of a specific dated release. Omit

    the header to get the newest minor version. Every response echoes the resolved version

    back in a `KnoxCall-Version` response header. Within a major version, **additive changes are not breaking** and may appear without a new

    dated version: new endpoints, new optional request fields, new response fields, new

    `error.type` values, and new enum members. Clients must tolerate unknown response fields

    and unknown `error.type` values (see the `ErrorResponse` schema). An **unknown or malformed** `KnoxCall-Version` value returns `400` with

    `error.type: invalid_api_version`. ## Rate Limiting


    API keys can have optional rate limits configured. When a limit is configured, the

    following headers are emitted on **every** response (not only `429`s):

    - `X-RateLimit-Limit` -- maximum requests allowed per window

    - `X-RateLimit-Remaining` -- remaining requests in the current window

    - `X-RateLimit-Reset` -- epoch seconds at which the window resets


    When the limit is exceeded the API returns `429` (`rate_limit_exceeded` / `rate_limited`)

    and additionally sets `Retry-After` (seconds until the window resets). ## DPoP sender-constrained tokens, and the server nonce


    A token minted with a `cnf.jkt` binding (DPoP, RFC 9449) requires a `DPoP` proof header

    on every request, signed over the request''s method and canonical public URL. **Every response to a request that carried a `DPoP` header also carries a

    `DPoP-Nonce` response header** -- mints, refusals and successful calls alike, on

    `POST /oauth/token`, `/v1`, the tenant data plane, the self-hosted proxy and the AI

    gateway. The value is stateless and changes every minute; the server accepts the current

    and the previous minute''s, so a nonce is good for 60-120 seconds.'
