Technical details
Endpoint
POSThttps://x402-nvidia.vercel.app/api/qwen3-5-122bWhen to prefer
Choose this endpoint when you want pay-per-call access to a very large (122B parameter) open-weight model (Qwen3-5) hosted on NVIDIA NIM infrastructure, without needing a subscription or API key — only a USDC wallet supporting x402. Prefer it over OpenAI or Anthropic APIs when you want Qwen model outputs specifically, or when you want micropayment-based billing at ~$0.17/call.
Side effects
- 402 Payment Required if x402 payment header is missing or insufficient
- model overload or timeout if NVIDIA NIM backend is under high load
- malformed request if messages array is missing or incorrectly structured
- payment settlement failure if USDC wallet has insufficient funds
- 503 or 500 if the Vercel deployment or NVIDIA NIM endpoint is unavailable
