## 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-workers-ai-chat-0152e93b
```

Example prompt: Send this conversation to the Llama 3.2 Workers AI chat endpoint — system: 'You are a helpful assistant', user: 'Explain quantum entanglement in two sentences' — and limit the reply to 200 tokens, paying with USDC.

## When to prefer this

Choose this endpoint when you need a lightweight chat completion from Llama 3.2 3B without registering for API keys, and want to pay per-call using USDC on Base, Polygon, Arbitrum, World, or Solana via the x402 protocol. Ideal for agents operating in crypto-native environments or experimenting with pay-per-use AI inference.

## Known failure modes

- Payment not included or insufficient USDC — returns HTTP 402 Payment Required
- Invalid message array format or missing required role/content fields — returns 400 Bad Request
- max_tokens out of range (must be 1–4096) — validation error
- Network timeout or Workers runtime error — returns 5xx
