OpenAI-compatible chat completions paid per request in USDC-SPL on Solana via x402: POST /v1/chat/completions without a PAYMENT-SIGNATURE header returns an HTTP 402 challenge quoting the USDC cost; sign the quoted exact or escrow payment and resubmit. GET /v1/models lists 44 models with per-token USDC pricing, GET /v1/receipts/{receipt_id} returns the payment receipt for a paid call, and GET /health is the liveness probe. Zero-priced NVIDIA NIM and Gemini Flash-Lite models are served free without any payment.
