# API Reference

The current FastAPI application uses:

```text theme={null}
/api/v1
```

as its default API prefix.

## Major route groups

```text theme={null}
/auth
/admin
/connectors
/credentials
/sources
/streams
/connectors-registry
/audit-logs
/backup
/mappings
/enrichments
/destinations
/routes
/logs
/runtime
/ingest
/retention
/delivery
/validation
/governance
```

Safe-change and Test Before Apply endpoints are mounted under `/runtime`. Environment-promotion endpoints are mounted under `/backup`.

## Health

```http theme={null}
GET /health
```

returns API health plus a delivery-log index probe when PostgreSQL is reachable.

## Authentication

Most production API calls require a bearer access JWT from:

```http theme={null}
POST /api/v1/auth/login
```

## OpenAPI

FastAPI generates an OpenAPI schema from the running implementation. Treat the OpenAPI output of the exact version you operate as the authoritative endpoint/field reference.

<Note>
  Historical AI modules exist in the repository, but the current application entry point explicitly does not mount AI Gateway HTTP routers as part of the Data Relay OSS product surface.
