## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402-nvidia-paligemma-vision-api-f819cc12 -d '<json body>'
```

Example prompt: Can you use the PaliGemma vision model to look at this image and tell me what objects are in it and describe the scene in detail?

## When to prefer this

Choose this endpoint when you need PaliGemma-specific vision-language inference (Google's PaliGemma model hosted on NVIDIA NIM) via pay-per-call micropayments at ~$0.06 per call with no subscription required, ideal for agents needing flexible, low-commitment multimodal image understanding without managing NVIDIA API credentials directly.

## Known failure modes

- Payment not included or invalid x402 micropayment header — 402 Payment Required
- Malformed request body missing required vision prompt or image — 400 Bad Request
- Model inference timeout for complex images — 504 Gateway Timeout
- NVIDIA NIM backend unavailable — 503 Service Unavailable
- Exceeded rate limits — 429 Too Many Requests
