Example use cases
Real-time customer support chatbot
“I need you to handle a customer question about our product warranty. Call an NVIDIA NIM model to draft a helpful response, stream it back to me, and charge only for what we use via x402 micropayments.”
Content moderation for user uploads
“Check if this user-submitted comment is safe and appropriate. Use an NVIDIA safety model through x402 to analyze it, stream back the safety assessment, and we'll pay only per check.”
Multi-language customer feedback analysis
“We got feedback in three different languages. Run each through an NVIDIA NIM translation model via x402 to convert them to English, stream the results back, and bill us per translation only.”

Endpoint
POSThttps://x402-nvidia.vercel.app/api/streampetrWhen to prefer
Choose this endpoint when you need on-demand, pay-per-call access to NVIDIA NIM AI models (including vision, safety, and translation models) without managing subscriptions or API keys — ideal for agents that need cost-controlled, per-inference billing via x402 USDC micropayments and require streaming completions from NVIDIA-hosted models.
Side effects
- Payment not included or insufficient USDC causes 402 Payment Required response
- Invalid or malformed choices array in request body causes 400 Bad Request
- Requested NVIDIA NIM model unavailable or quota exceeded causes 503 or 429 error
- Network timeout if streaming response takes too long
- Missing required message fields causes parsing error
