Step-by-step guides to integrate Bear Lumen. Start with the quickstart, then wire up the SDK or the REST API.

Getting Started

New to Bear Lumen? Start here and pick your integration path: SDK or REST API.

Install the SDK, track your first AI call, and attribute it, in five minutes.

Complete reference for the Node.js and Python SDKs, with a language toggle.

Handle SDK errors gracefully with typed error classes and retry strategies.

Use the Bear Lumen REST API directly with cURL or any HTTP client.

Every model we price, by provider. Set custom rates for models we do not list yet.
