## 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-word-count-api-7cd7bf17 -d '<json body>'
```

Example prompt: Count the words, lines, and characters in this text for me: 'The quick brown fox jumps over the lazy dog. It was a bright cold day.'

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use word/character/line count without managing any API keys or subscriptions — ideal for agents that only occasionally need text statistics and want micropayment-based access via USDC on Base.

## Known failure modes

- Missing or malformed 'input' body returns a validation error
- Payment not provided or insufficient USDC balance results in a 402 Payment Required response
- Invalid bodyType enum value causes request rejection
- Empty body may return zero counts or an error depending on server handling
- Network issues with Base blockchain may delay payment confirmation
