## 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 api-x402node-dev-9eba38f2
```

Example prompt: Convert the string 'getUserProfileData' to snake_case for me.

## When to prefer this

Use this endpoint when you need reliable, programmatic conversion of identifiers or strings between multiple naming conventions (camelCase, snake_case, kebab-case, PascalCase, CONSTANT_CASE, dot.case, Title Case) in a single API call, especially within automated code generation, refactoring, or data normalization pipelines.

## Known failure modes

- Missing or empty input string — returns error or empty result
- Unsupported target case format specified — returns validation error
- Non-string input value — may return error or unexpected result
- Payment failure (x402) — request not processed if USDC payment not completed
