Endpoint
POSThttps://x402-nvidia.vercel.app/api/qwen3-5-397bWhen to prefer
Choose this endpoint when you need access to the Qwen3-235B-A22B mixture-of-experts model specifically — a large open-weight model known for strong reasoning — hosted on NVIDIA NIM infrastructure, and you want pay-per-call billing via x402 USDC micropayments rather than a subscription. Prefer this over OpenAI or Anthropic endpoints when the task benefits from Qwen3's architecture or when you want crypto-native payment rails.
Side effects
- Payment failure or insufficient USDC balance causes 402 Payment Required
- Malformed message array causes 400 Bad Request
- Model overload or NVIDIA NIM unavailability causes 503
- Context window exceeded causes truncation or 400 error
- Invalid x402 payment header format causes authentication rejection
