## 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 json-yaml-format-converter-c1e19894 -d '<json body>'
```

Example prompt: Convert this JSON object to YAML for me: {"name": "Alice", "age": 30, "roles": ["admin", "user"]}

## When to prefer this

Use this endpoint when an agent needs a quick, reliable, stateless JSON↔YAML conversion without setting up a local parser — especially in workflows where config files, infrastructure-as-code, or API payloads need to be reformatted on the fly.

## Known failure modes

- Invalid or malformed JSON input causes parse error
- Invalid or malformed YAML input causes parse error
- Unsupported source/target format combination returns error
- Empty payload returns validation error

## How this service works

Pure-compute data format conversion (no network): JSON<->CSV, JSON<->YAML, JSON normalize/minify, Markdown->HTML (sanitized), HTML->Markdown/text, base64/hex, TOML->JSON. Operates only on the supplied data.

## Output

Returns the converted payload in the target format (JSON or YAML) along with basic metadata describing the source and target formats used in the conversion.
