Developer console →

Protect your keys

Create an API key in the console and check model permissions, quotas and credit. Read keys from server-side environment variables, never from frontend code or public repositories.

2Your first request

Save your key as LLMAPI_API_KEY. Use /v1/models to find an authorized chat model and replace YOUR_MODEL_ID. Run these examples on the server; real calls consume usage.
