AI Gateway

Access 340+ AI models (OpenAI, Anthropic, Google, Meta, Mistral, DeepSeek, and more) through the Agnic AI Gateway. Costs are deducted from your USDC balance per token. Free models available for development.

Authentication

Run npx agnic@latest status --json to verify. If not authenticated:

• Headless (CI/server/agent): Set AGNIC_TOKEN env var or pass --token <token>
• Interactive (has browser): Run npx agnic@latest auth login

See the authenticate-wallet skill for details.
