title: KnoxCall Client Management Opportunities 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.'
