## 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 api-the402-ai-c06e94f7 -d '<json body>'
```

Example prompt: Can you summarize this article for me — https://example.com/long-article — I just want the key points in a few sentences?

## When to prefer this

Use this endpoint when an AI agent needs to quickly condense a URL or block of text into a summary and is operating within an x402 micropayment-enabled environment; ideal for agents that need lightweight, pay-per-use summarization without a subscription commitment

## Known failure modes

- Text input exceeds maximum length — request rejected
- Payment of 0.011 USDC not completed or x402 header missing — 402 Payment Required returned
