## 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 nexusapi-character-count-674e7347 -d '<json body>'
```

Example prompt: How many characters are in this text: 'The quick brown fox jumps over the lazy dog'?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call character count without setting up API keys or running local string-length logic. Ideal for AI agents validating text against character limits (SMS, Twitter, form fields) in automated workflows where a remote computation step is acceptable.

## Known failure modes

- Empty input string returns zero or an error
- Very long strings may be truncated or rejected
- Non-string input types may cause a validation error
- Network or payment failure returns a 402 or 5xx response
