-Continue / Cursor / IDE Extensions - -In your configuration file (e.g., `config.json`): - -```json -{ - "models": [ - { - "title": "Gemini via Proxy", - "provider": "openai", - "model": "gemini/gemini-2.5-flash", - "apiBase": "http://127.0.0.1:8000/v1", - "apiKey": "your-proxy-api-key" - } - ] -} -``` - -
- -
-Claude Code - -Claude Code natively supports custom Anthropic API endpoints. The recommended setup is to edit your Claude Code `settings.json`: - -```json -{ - "env": { - "ANTHROPIC_AUTH_TOKEN": "your-proxy-api-key", - "ANTHROPIC_BASE_URL": "http://127.0.0.1:8000", - "ANTHROPIC_DEFAULT_OPUS_MODEL": "gemini/gemini-3-pro", - "ANTHROPIC_DEFAULT_SONNET_MODEL": "gemini/gemini-3-flash", - "ANTHROPIC_DEFAULT_HAIKU_MODEL": "openai/gpt-5-mini" - } -} -``` - -Now you can use Claude Code with Gemini, OpenAI, or any other configured provider. - -

-Anthropic Python SDK - -```python -from anthropic import Anthropic - -client = Anthropic( - base_url="http://127.0.0.1:8000", - api_key="your-proxy-api-key" -) - -# Use any provider through Anthropic's API format -response = client.messages.create( - model="gemini/gemini-3-flash", # provider/model format - max_tokens=1024, - messages=[{"role": "user", "content": "Hello!"}] -) -print(response.content[0].text) -``` - -
