## 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 gedx402-mistral-small-3-1-24b-instruct-llm-09ae0bf6
```

Example prompt: Chat with the Mistral Small 3.1 24B model and answer this question — no API key, just pay per call in USDC: 'Explain the difference between supervised and unsupervised learning in three sentences.' Limit the reply to 300 tokens.

## When to prefer this

Choose this endpoint when you need a capable mid-size open instruction-following model (24B parameters) without API key registration, want to pay programmatically per-call in USDC on Base, Polygon, Arbitrum, World, or Solana via x402, and are building agents that require permissionless LLM access billed on-chain.

## Known failure modes

- Insufficient USDC balance or failed x402 payment — returns 402 Payment Required
- Invalid message role (not system/user/assistant) — schema validation error
- max_tokens exceeds 4096 — rejected by schema validation
- Empty or malformed messages array — likely 400 Bad Request
- Network timeout or Cloudflare Workers AI upstream unavailability — 5xx error
