## 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-chat-ca25d464
```

Example prompt: Chat with the Hermes-2-Pro-Mistral-7B model: system prompt 'You are a helpful assistant', user message 'Explain the concept of zero-knowledge proofs in simple terms', and limit the response to 512 tokens.

## When to prefer this

Choose this endpoint when you need LLM chat completions without API key management, prefer paying per-call in USDC on EVM-compatible chains or Solana, or want to use the NousResearch Hermes-2-Pro-Mistral-7B model specifically via Cloudflare Workers AI infrastructure. Ideal for agents operating in crypto-native environments where x402 micropayments are already supported.

## Known failure modes

- Payment not received or insufficient USDC balance — HTTP 402 returned, no inference performed
- Invalid message format (missing role or content fields) — request rejected with schema validation error
- max_tokens exceeds 4096 — request rejected
- Worker timeout if prompt is very long or model is slow to respond
- Unsupported blockchain network specified for payment — payment fails
