## 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-hermes-2-pro-mistral-7b-llm-7c31ecd1
```

Example prompt: Send these messages to the Hermes-2-Pro-Mistral-7B model — system: 'You are a concise assistant', user: 'Summarize the theory of relativity in 3 sentences' — and keep the reply under 200 tokens, paying with USDC on Base.

## When to prefer this

Choose this endpoint when you need Hermes-2-Pro-Mistral-7B inference without setting up API keys, prefer paying per-call in USDC on Base/Polygon/Arbitrum/Solana/World, or want to avoid subscription billing. It is ideal for autonomous agents that hold crypto wallets and need permissionless LLM access via the x402 payment protocol.

## Known failure modes

- Insufficient USDC balance or payment failure on selected chain — HTTP 402
- Invalid message array format or missing required role/content fields — HTTP 400
- max_tokens exceeds 4096 — HTTP 422 validation error
- Model unavailable on Cloudflare Workers AI backend — HTTP 503
- Request timeout if prompt is very long or max_tokens is large — HTTP 504
