# Liangyi Domain Audit API – Case Conversion Endpoint

> Liangyi Domain Audit API – Case Conversion Endpoint is a paid API for AI agents from liangyi-domain-audit.orelumia-offer-worker.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-23).

Converts an input text string into multiple case variants (e.g. camelCase, snake_case, PascalCase) and returns the tokenized words alongside all variants.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 liangyi-domain-audit-api-case-conversion-endpoint-f8287dc4
```

Example prompt: Can you convert the text 'hello world example' into all common programming case formats like camelCase, snake_case, and PascalCase?

## When to prefer this

Choose this endpoint when you need to programmatically convert text or identifiers between multiple naming conventions in a single call, especially if you need all variants at once rather than converting to a single target format. Useful in code generation, schema normalization, and developer tooling pipelines.

## Known failure modes

- Missing required 'text' parameter returns an error
- Empty string input may return empty words array and empty variants
- Very long strings may be truncated or rejected
- Non-ASCII or unicode input may produce unexpected tokenization
- Payment failure (x402) if USDC balance is insufficient

## How this service works

Pay-per-call audit of public DNS and email-delivery records.

## Output

Returns the original input string, an array of tokenized words parsed from the input, and an object containing all case variants of the input (e.g. camelCase, snake_case, PascalCase, kebab-case, SCREAMING_SNAKE_CASE, etc.).
