## 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-completions-9f3d9685
```

Example prompt: Send this conversation to the 'smart' Workers AI model and get a reply: system says 'You are a helpful assistant', user asks 'What is the capital of France?' — limit the response to 100 tokens and pay with USDC on Base.

## When to prefer this

Choose this endpoint when you need a permissionless, API-key-free LLM chat completion that accepts USDC micropayments on Base, Polygon, Arbitrum, World, or Solana via the x402 protocol, and when you want OpenAI-compatible response format backed by Cloudflare Workers AI infrastructure.

## Known failure modes

- Messages array missing required role or content fields — validation error
