## 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 pennyrail-text-word-count-3ebed346 -d '<json body>'
```

Example prompt: Can you count the words and get text stats for this paragraph: 'The quick brown fox jumps over the lazy dog. It was a bright and sunny afternoon.'

## When to prefer this

Choose this endpoint when you need a fast, cheap, programmatic word count or text statistics computation via a pay-per-call micropayment model. It is ideal for agents that process many small text snippets on demand without needing a full NLP pipeline or heavyweight text analysis service.

## Known failure modes

- Missing 'input' field returns a 400 or validation error
- Empty string input may return zero counts or an error
- Very large text inputs may hit payload size limits
- Payment failure (x402) if USDC not provided or insufficient balance
