## 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 primeapi-word-count-106de97b -d '<json body>'
```

Example prompt: Can you count the words in this paragraph for me: 'The quick brown fox jumps over the lazy dog and then runs away into the forest'?

## When to prefer this

Use this endpoint when you need a simple, reliable word count for a text string and want a pay-per-call approach with no API key setup. Suitable for one-off word count checks or lightweight integrations where a full NLP library is overkill.

## Known failure modes

- Empty input string returns zero or an error
- Non-string input may cause a validation error
- Very large text inputs may time out or be truncated
- Payment of 0.16305 USDC on Base must succeed before the call is processed; insufficient funds returns a 402 error
