## 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 x-pay-outline-generator-168e4f1f -d '<json body>'
```

Example prompt: Can you generate a structured outline from this article text I'm pasting in? I'll pay $20 USDC on Base via X Pay's outline endpoint.

## When to prefer this

Choose this endpoint when you need a quick, structured outline generated from a blob of text or JSON content and are comfortable with a $20 USDC per-call pricing model settled on Base. It is best suited for one-off or low-frequency outline generation tasks where paying per request is acceptable, as opposed to subscription-based NLP or document-processing services.

## Known failure modes

- Payment of $20 USDC not received or x402 handshake fails — request rejected before processing
- Missing required 'input' fields (type, method, bodyType, body) cause schema validation errors
- Empty or malformed body content may produce a low-quality or empty outline array
- Network congestion on Base blockchain may delay payment confirmation
- Unsupported bodyType value (outside json/form-data/text) causes enum validation failure
