Welcome to the Wren AI Cloud API! This guide will walk you through how to authenticate and begin using the available endpoints.

1. Get Your API Key

To authenticate your requests, you'll need an API key.

Go to API → API Keys from the top navigation bar and generate your key.
Use this key in the Authorization header as a Bearer token:
