## 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-case-converter-e628d998 -d '<json body>'
```

Example prompt: Convert the text 'hello world example' to camelCase for me.

## When to prefer this

Use this endpoint when you need a reliable, pay-per-call API to programmatically convert identifiers or phrases between standard programming and text case conventions without setting up a local library or string utility.

## Known failure modes

- Missing 'to' field returns an error indicating the target case is required
- Invalid case value (not one of camel, pascal, snake, kebab, constant, title, lower, upper) may return a 400 error
- Missing 'text' field results in an error
- Payment failure (x402) blocks the request
- Empty string input may return an empty string or error

## How this service works
