Welcome

The Delphi API can be used to build interactive, AI data applications for your customers. All functions that use large language models (LLMs) are grouped under Delphi (Natural Language). Note that settings and configuration should generally be handled via our platform UI, not API.

​
Authentication

All API endpoints are authenticated using two request headers: X-CLIENT-ID and X-API-KEY. Your API key is considered a secret, so it should only be used from the backend; you should not call these routes directly from your frontend. The exception is the Delphi (Natural Language) Chat Workflow endpoint, which is meant to be called from the frontend. See its page for more information.
