## 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-client-code-generator-python-javascript-178dea86 -d '<json body>'
```

Example prompt: Generate Python and JavaScript x402 v2 client code from my OpenAPI spec at https://api.myservice.com/openapi.json so I can start making x402-enabled API calls right away.

## When to prefer this

Choose this endpoint when you need to quickly scaffold x402 v2-compatible client code in Python or JavaScript directly from an existing OpenAPI spec, avoiding manual implementation of the x402 payment handshake. It is especially useful for developers integrating with x402-enabled APIs who want auto-generated, protocol-correct client libraries rather than writing boilerplate payment handling code themselves.

## Known failure modes

- Invalid or unparseable OpenAPI spec returns an error
- Neither spec object nor spec_url provided causes a validation error
- Unreachable spec_url results in a fetch/timeout error
- Malformed spec_url (not a valid URI) causes rejection
- Spec missing required OpenAPI fields may produce incomplete client code
- Payment not fulfilled (402) if x402 payment header is missing or invalid
