AI Tool Setup

Claude Code

Configure Claude Code to route Anthropic-compatible model calls through Felo API Platform.

Use this guide when you want Claude Code to use Felo API Platform instead of calling the model vendor directly. Claude Code uses an Anthropic-compatible Messages endpoint.

Before You Start

You need one Felo API Platform key. The same key works across model protocols, agent clients, Search, Web Fetch, PPT, Mindmap, LiveDocs, X Search, YouTube Subtitling, Landing Page, and SuperAgent APIs.

export FELO_API_KEY="YOUR_API_KEY"

Recommended Setup

Item	Value
Best for	repo editing, coding agents, long-context research, and terminal-first development
Protocol	Anthropic-compatible Messages API
Base URL	`https://openapi.felo.ai/api`
Model example	`claude-sonnet-4-6`
API key	Your `FELO_API_KEY`

Configure Claude Code

Set the environment variables first:

export FELO_API_KEY="YOUR_API_KEY"
export ANTHROPIC_API_KEY="$FELO_API_KEY"
export ANTHROPIC_BASE_URL="https://openapi.felo.ai/api"
export ANTHROPIC_MODEL="claude-sonnet-4-6"

Optional settings file

Use a settings file when you want the base URL and model to apply every time Claude Code starts. Keep the API key in your shell or secret manager.

{
  "env": {
    "ANTHROPIC_BASE_URL": "https://openapi.felo.ai/api",
    "ANTHROPIC_MODEL": "claude-sonnet-4-6"
  }
}

You can also choose a model for one session:

claude --model claude-sonnet-5

Verify the Setup

Run a small task after saving the configuration:

claude

If the tool starts and answers with the selected model, the provider setup is ready.

Troubleshooting

Issue	What to check
Authentication fails	Confirm the key is copied correctly and exported as `FELO_API_KEY`
Tool calls the wrong provider	Check that the Felo provider is selected for the current workspace or session
Base URL error	Use `https://openapi.felo.ai/api/v1` for OpenAI-compatible clients and `https://openapi.felo.ai/api` for Anthropic-compatible clients
Model not found	Choose a model that appears in your Felo model list
The tool ignores local config	Move provider settings to the user-level config if the client requires it
