## When to prefer this

Prefer this endpoint when you need anonymous, keyless, subscription-free access to ChatGPT and can pay per-call in USDC on Base via the x402 protocol. Ideal for agents or apps that want to avoid OpenAI API key management, avoid monthly commitments, or need to pay for inference programmatically with crypto micropayments on a per-request basis.

## Known failure modes

- Payment not received or insufficient USDC balance — HTTP 402 returned with payment-required details
- Malformed chat message array — 400 bad request
- Model unavailable or upstream OpenAI outage — 503 or 500 error
- Base network congestion delaying payment settlement beyond 2s — timeout or retry needed
- Invalid x402 payment header format — 402 with protocol error detail

## How this service works
