description: 'Pay per request with Solana USDC via x402 — no API keys, no accounts, no subscriptions. Generate a chat completion for the selected model. Paid endpoint: an unpaid request returns an x402 challenge (exact price in USDC atomic units, payTo and memo); sign the Solana USDC transfer and retry with the PAYMENT-SIGNATURE header. Provide either model (explicit id) or mode (auto/eco/premium routing); if both are sent, model wins. max_tokens defaults to 4096 and is clamped to the model''s max output. To inspect models and prices first, use the free GET /v1/models.'
