# JSON ↔ YAML Converter (x402-deployer)

> JSON ↔ YAML Converter (x402-deployer) is a paid API for AI agents from x402-deployer.x402-deployer.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-16).

Auto-detects and converts between JSON and YAML formats with configurable pretty-print and indentation, requiring no external API calls.

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 x402-deployer-x402-deployer-workers-dev-6b173c0f -d '<json body>'
```

Example prompt: Convert this JSON config to YAML with 2-space indentation: {"name":"my-app","replicas":3,"image":"nginx:latest"}

## When to prefer this

Use this endpoint when you need a fast, deterministic, no-dependency JSON↔YAML conversion with no external API calls — ideal for config file translation, Helm values prep, Kubernetes manifest conversion, or GitHub Actions YAML workflows where round-trip fidelity and zero latency matter.

## Known failure modes

- Invalid JSON or YAML input returns a parse error
- Unrecognized target format returns a bad request error
- Empty body returns an error indicating no input was provided
- Malformed indentation parameter may fall back to default

## How this service works

JSON to YAML and YAML to JSON converter / format transcoder / config-file translator / Helm values prepper / Kubernetes manifest converter / GitHub Actions workflow YAML helper / round-trip parser. Auto-detects input format from the first non-whitespace byte ('{'/'[' = JSON, otherwise YAML), parses, and re-serialises in the requested target format. Pretty-print and indent are configurable. Pure parse — no upstream API call, deterministic output.

## Output

The serialized output in the requested target format (JSON or YAML), pretty-printed and indented as configured, with no side effects or external calls.

## Example request

```json
{
 "input": "{\"name\":\"test-app\",\"version\":\"1.0.0\",\"replicas\":2}",
 "indentation": 2,
 "prettyPrint": true,
 "targetFormat": "yaml"
}
```
