## 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 24k-labs-case-converter-api-9ad94c4c -d '<json body>'
```

Example prompt: Can you convert 'hello world from my app' to camelCase?

## When to prefer this

Use this endpoint when an agent needs to programmatically reformat text identifiers or display strings into a specific casing convention — especially for code generation, database schema work, API field normalization, or UI content formatting. Prefer this over manual string manipulation when multiple target formats are needed or when the source format is unknown.

## Known failure modes

- Missing or empty input text returns an error
- Unsupported case format name returns an error
- Very long strings may be truncated or rejected
- Non-ASCII or special characters may produce unexpected results in some case formats
