## 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-convert-json-yaml-converter-50949dc7 -d '<json body>'
```

Example prompt: Convert this JSON object to YAML for me: {"name": "x402", "tags": ["a", "b"]}

## When to prefer this

Choose this endpoint when you need a deterministic, pay-per-use JSON↔YAML conversion without setting up a local parser or dependency. Ideal for AI agents operating in serverless or sandboxed environments where installing libraries is not an option, and when you want a simple per-call micropayment model rather than a subscription.

## Known failure modes

- Invalid or malformed YAML input returns an error response
- Supplying both 'json' and 'yaml' fields simultaneously may cause ambiguous behavior
- Empty input body or missing both fields returns an error
- Payment failure via x402 (insufficient USDC balance or wrong network) prevents the call from executing
- Extremely large payloads may hit Cloudflare Workers size limits

## How this service works

## Output

A JSON object containing either a 'yaml' field with the YAML-formatted string (when input is JSON) or a 'json' field with the parsed JSON value (when input is YAML).
