Endpoint overview

Overview

FHRouter uses one account and one API key across Claude, GPT, and Gemini model families.

The shared endpoint host is:

https://api.fhrouter.com

Different client families attach different protocol paths to that same host.

Which path should I use?

Client	Base URL
Claude Code and Anthropic-native clients	https://api.fhrouter.com
Codex CLI and OpenAI-compatible clients	https://api.fhrouter.com/v1
Gemini CLI and Gemini-native clients	https://api.fhrouter.com/v1beta

What you need before setup

• an FHRouter account
• wallet balance
• an FHRouter API key
• the exact model id you want to call
• the matching client guide

Common path mistakes

1. using the root host with an OpenAI-compatible app that actually needs /v1
2. using /v1 for Claude Code instead of the root host
3. using /v1 instead of /v1beta for Gemini-native tools
