```sh
zero fetch --capability gedx402-mistral-7b-instruct-llm-x402-usdc-ef60e2c1
```

## When to prefer this

Choose this endpoint when you need Mistral-7B-Instruct inference without managing API keys or subscriptions, and you can pay per-call in USDC via the x402 protocol on Base, Polygon, Arbitrum, World, or Solana. Ideal for agentic workflows that need autonomous LLM calls billed directly on-chain.

## Known failure modes

- Insufficient USDC balance or failed on-chain payment — HTTP 402 with payment required details
- Invalid messages array (missing role or content fields) — HTTP 400 validation error
- max_tokens out of range (less than 1 or greater than 4096) — HTTP 400
- Model inference timeout or upstream Workers AI error — HTTP 500
- Unsupported blockchain network for payment — payment not accepted
