## 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 openweb-ninja-copilot-ai-chat-x402-eb29bc28 -d '<json body>'
```

Example prompt: Ask Copilot in REASONING mode: 'What are the main differences between supervised and unsupervised machine learning?' and return the answer in markdown format.

## When to prefer this

Choose this endpoint when you need to access Microsoft Copilot (including REASONING or GPT-5/SMART modes) on a per-call basis without setting up an API key or account — ideal for agents making occasional AI queries with USDC micropayments via x402, or when you specifically want Copilot's Bing-grounded responses rather than a raw OpenAI API call.

## Known failure modes

- Payment failure if x402 USDC transaction is not completed or insufficient balance
- Invalid or expired conversation_id causing loss of conversation context
- Unsupported mode value causing a bad request error
- Empty or missing message field resulting in an error response
- Rate limiting or upstream Copilot service unavailability causing 5xx errors
- Malformed response if Copilot service is temporarily degraded
