## 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-solar-10-7b-chat-completions-5a2fa71d -d '<json body>'
```

Example prompt: Use the Solar-10-7B NVIDIA NIM model to answer this question: 'What are the main differences between supervised and unsupervised learning?' — pay the per-call fee automatically.

## When to prefer this

Choose this endpoint when you need access to NVIDIA's Solar-10-7B model specifically via pay-per-call USDC micropayments (x402 protocol), avoiding subscription commitments. Ideal for agents that need occasional LLM inference without managing API keys, or when integrating into crypto-native workflows where on-chain micropayments are preferred.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 payment rejected
- Model unavailable: NVIDIA NIM Solar-10-7B endpoint is down or rate-limited
- Malformed input: missing or incorrectly structured messages array
- Authentication error: invalid or missing x402 payment header
- Timeout: model inference takes too long and request times out
