Chatley AI

Chatley Developer API

The Chatley Developer API lets you create chat sessions with your Chatley agents and send them messages from your own application (POST /api/developer/chat/sessions, POST /api/developer/chat/messages), authenticated with a Chatley API key sent as a Bearer token. Chatley publishes no machine-readable contract for it; the OpenAPI here is generated from the documentation pages.
