# API reference

> The Visceral backend HTTP API.

The Visceral backend is served at `https://api.visceralai.dev`. Requests are
authenticated with your workspace API key.

The endpoints in this section are grouped by area:

* **Auth** (`/v1/auth/*`) — signup, login, token refresh, and the device-authorization
  flow used by the [CLI](/cli/overview).
* **Workspaces & keys** (`/v1/workspaces`, `/v1/keys`) — manage workspaces and the
  API keys the [SDK](/sdk/installation) uses.
* **Ingestion** (`/v1/otlp/v1/traces`) — the OTLP endpoint the SDK reports events to.
* **Health** (`/healthz`, `/readyz`) — liveness and readiness probes.

<Note>
  The endpoint pages below are generated from the backend's OpenAPI specification
  (`api-reference/openapi.json`). Run `scripts/sync-openapi.sh` to refresh it from a
  running backend — see the repo README.
