## 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-text-rewrite-api-a9cff849 -d '<json body>'
```

Example prompt: Rewrite this text to sound more polished and professional using the X Pay text rewrite API: 'our product is good and people like it a lot and you should buy it today'.

## When to prefer this

Choose this endpoint when you need lightweight, pay-per-use text rewriting without a subscription, especially in autonomous agent workflows that already handle x402/USDC micropayments on Base. Ideal when you want to avoid API key management and pay only for what you use.

## Known failure modes

- Payment not received or insufficient USDC balance — 402 error returned
- Missing required fields (type, method, bodyType, body) — validation error
- Invalid bodyType enum value — request rejected
- Empty or malformed body object — unclear rewrite output
- Network congestion on Base causing payment settlement delay
