Introduction

Welcome to the Fern API Reference.
View as Markdown

The Fern AI API allows you to manage your Ask Fern configuration using Fern’s public RESTful API. You can use the API to:

  • Build your own support integrations that leverage Ask Fern’s AI-powered search
  • Add custom context and FAQs to your documentation
  • Source usage and analytics data from your Ask Fern instances

Authentication

Fern API requests require an API key for authentication. Use the CLI command fern token or the API keys page in the Dashboard to generate an API key. API keys don’t expire.

Only organization Admins can generate API keys. If you have the Editor or Viewer role, ask an Admin to generate a key for you. Once you have a key, calling the API doesn’t require any additional role.
