## 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 agenttools-text-case-converter-8df027a8
```

Example prompt: Can you convert the text 'hello world example' to camelCase for me?

## When to prefer this

Use this endpoint when an agent needs programmatic, reliable text case conversion across all nine common conventions — especially when automatic camelCase boundary splitting is needed. Prefer this over regex-based in-agent logic when determinism and coverage across all nine styles is required.

## Known failure modes

- Missing required 'text' query parameter returns an error
- Invalid 'style' enum value returns a validation error
- Empty string input may return an empty string or error
- Very long strings may be truncated or time out

## How this service works

Convert text between nine letter cases: UPPER, lower, Title, Sentence, camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE. camelCase boundaries are split automatically. Use this when an agent needs to camelCase, snake_case, kebab-case and more.

## Output

The API returns the input text reformatted in the requested case style (e.g. 'helloWorld', 'hello_world', 'HELLO_WORLD'). camelCase and PascalCase conversions automatically detect word boundaries even in already-cased input.
