## 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 agent402-tools-text-counter-1d68afda -d '<json body>'
```

Example prompt: Can you count the characters, words, and lines in this text, and also tell me how many times the word 'cloud' appears: 'The cloud is a powerful tool. Many companies rely on the cloud for storage. The cloud continues to grow.'

## When to prefer this

Use this endpoint when you need a quick, reliable computation of basic text statistics — character count, word count, line count — and optionally a substring frequency count, without needing NLP, sentiment, or semantic analysis. Ideal for content editors, writing assistants, or any agent verifying text length or keyword density.

## Known failure modes

- Missing 'text' field in request body returns a validation error
- Empty string input may return zero counts for all metrics
- Very large text inputs may time out or exceed payload limits
- Malformed JSON body returns a 400 error

## How this service works

Count characters, words, lines, and (optionally) occurrences of a substring in text.

## Output

Returns a breakdown of the text including total character count, word count, line count, and if a 'find' substring was provided, the number of times that substring appears in the text.
