## 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 agent-hub-mistral-small-3-1-24b-chat-completions-246f7386
```

Example prompt: Ask Mistral Small 3.1 24B: 'Summarize the key risks in this product roadmap and suggest three mitigations' — pay per call, no API key needed, up to 2048 tokens in the response.

## When to prefer this

Choose this endpoint when you want Mistral Small 3.1 24B specifically — a capable 24B model with strong reasoning, vision, and tool-calling — and prefer pay-per-call x402 micropayments over monthly API subscriptions. Ideal for agent workflows that need occasional LLM calls without managing API keys, or when testing Mistral's capabilities at low cost per invocation.

## Known failure modes

- Payment failure or insufficient USDC balance returns 402 with x402 payment-required details
- Prompt exceeding context window returns a 400 or truncated response
- Invalid tool schema causes tool-call parsing errors
- Image input format not supported returns an error or ignored image
- Rate limiting or server overload may return 429 or 503
