## 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-ce51722f -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 simple, pay-per-call character count without managing API keys, particularly useful in automated workflows where text length validation is needed and USDC micropayments on Base are acceptable

## Known failure modes

- Empty or missing query parameter returns an error or zero count
- Non-string input may cause a 400 bad request
- Service unavailable if payment fails (402 payment required)
- Extremely long strings may hit payload size limits

## How this service works
