## Create a relay

**post** `/accounts/{account_id}/moq/relays`

Provisions a new MoQ relay instance. Auto-creates a publish+subscribe
token and a subscribe-only token. Token values are included in the
response (shown once). Config is set to defaults (lingering subscribe
enabled, 30s ceiling, origin fallback off). Use PUT to modify.

### Path Parameters

- `account_id: string`

  Cloudflare account identifier.

### Body Parameters

- `name: string`

  Human-readable name for the relay.

### Returns

- `errors: array of object { code, message }`

  - `code: optional number`

  - `message: optional string`

- `messages: array of object { code, message }`

  - `code: optional number`

  - `message: optional string`

- `success: boolean`

- `result: optional object { config, created, modified, 4 more }`

  Relay with auto-generated tokens (shown once).

  - `config: object { lingering_subscribe, origin_fallback }`

    origin_fallback and lingering_subscribe are mutually exclusive.

    - `lingering_subscribe: optional object { enabled, max_timeout_ms }`

      - `enabled: optional boolean`

      - `max_timeout_ms: optional number`

        Relay-level ceiling on lingering subscribe timeout (ms). Default 30000.

    - `origin_fallback: optional object { enabled, origins }`

      - `enabled: optional boolean`

      - `origins: optional array of object { url }`

        Ordered list of upstream origin relays. Each entry is an object
        (not a bare string) so per-origin configuration can be added in
        the future without another breaking change.

        - `url: optional string`

          Upstream origin relay URL.

  - `created: string`

  - `modified: string`

  - `name: string`

  - `token_publish_subscribe: string`

    Full access token (publish + subscribe). Treat as sensitive.

  - `token_subscribe: string`

    Subscribe-only token. Treat as sensitive.

  - `uid: string`

    Server-generated unique identifier (32 hex chars).
