## 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 tanod-utilpeek-case-conversion-39b3cdff -d '<json body>'
```

Example prompt: Convert this text to snake_case: 'My Variable Name Is Too Long'

## When to prefer this

Use this endpoint when you need deterministic, server-side case conversion for any of the 11 supported formats (including uncommon ones like dot, alternating, and constant) without writing custom regex or utility code. Ideal for agent pipelines normalizing user-supplied strings, code generators, or content formatters that need reliable multi-format support in a single API call.

## Known failure modes

- Invalid or missing 'to' enum value returns an error
- Text exceeding 200,000 characters is rejected
- Empty text string is rejected (minLength: 1)
- Malformed JSON body causes a bad request error
- Payment failure (x402) results in a 402 response before processing
