Build ATH agents and gateways using our official SDKs. The ATH protocol is language-agnostic — any HTTP client that can sign JWTs can implement an ATH client.

Getting Started

Each SDK provides the agent lifecycle methods that implement the ATH trusted handshake:
  • discover() — Learn what providers are available
  • register() — Register your agent, get approved for specific scopes
  • authorize() — Get a URL for the user to approve OAuth access
  • exchangeToken() — After user approves, get an ATH token with scope intersection
  • proxy() — Call the service API through the ATH gateway
Visit the SDK repository for your chosen language to find installation instructions, API documentation, and examples.

​
Building Your Own SDK

Want to build an SDK for a new language? You need to implement:
  1. JWT signing — ES256 agent attestation tokens
  2. HTTP client — Calls to the ATH API endpoints
  3. PKCE support — The gateway handles PKCE server-side, but your SDK should handle the authorization flow
See the API Specification for the complete endpoint reference.
