## 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 x402-toolbox-case-convert-eee25ff4
```

Example prompt: Can you convert the string 'myVariableName' to snake_case using the case-convert tool?

## When to prefer this

Choose this endpoint when you need a quick, stateless, pay-per-call text case conversion without signing up for an API key or managing credentials. Ideal for AI agents that need to normalize identifiers, field names, or slugs on the fly as part of an automated workflow, especially when integrated with the x402 micropayment protocol.

## Known failure modes

- Invalid or missing 'schema' parameter returns an error indicating unsupported case style
- Empty string input may return an empty result or validation error
- Payment failure on Base network causes a 402 response before conversion is attempted
- Unrecognized case style name returns an error or defaults unexpectedly

## How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

## Output

Returns a JSON object with 'ok: true' and 'paid: true' along with the case-converted output string after a $0.001 USDC micropayment is confirmed on Base.
