Relayer is organized into Kits. Each Kit covers a distinct domain and exposes a set of REST endpoints under the /v1 prefix. This page shows how the Kits relate to each other and to your application.

Request Flow

Every API request follows the same pattern:

​
Authentication Model

Every request authenticates with an API key in the Authorization header:
The API key identifies the integrator (your workspace) and determines which Kits and resources are accessible based on the workspace’s active modules and the caller’s role. Some surfaces also accept a session JWT (Authorization: Bearer <jwt>) for browser-side callers from the Relayer dashboard, and the Agent Kit accepts an HMAC-signed X-Agent-Auth header for runtime calls from the agent SDK. See Authentication for the full matrix.

​
Environments

All Kit endpoints and authentication patterns are identical across environments.
