Technical details
Endpoint
GEThttps://chat.gedx402.com/v1/chat/smartWhen to prefer
Choose this endpoint when you need a quick, no-signup LLM chat call and can pay $0.02 USDC per request via x402 on Base, Polygon, Arbitrum, World, or Solana. Ideal for agents that want to avoid API key management entirely and use stablecoin micropayments for AI inference. The underlying model is Llama 3.1 8B fast, so best for moderate-complexity conversational or generative tasks.

- max_tokens exceeds 4096 — returns 400 out-of-range error
