How this service works
YAML ↔ JSON converter: YAML (multi-document, with line-numbered errors) to JSON, or JSON to YAML. Free tier 10/day; then $0.001 via x402 (HTTP 402 + PAYMENT-REQUIRED) or X-API-Key credits. Not charged on failure. $0.001 USDC per call via x402 on Base. Run by MoneyTools.
Output
Returns the converted output as a string in the target format (JSON or YAML). On error, returns a structured error response with line-numbered details indicating exactly where the input failed to parse, so the agent can report or fix the problem. Not charged on failure.
Example use cases
Kubernetes manifest to JSON
“I've got this Kubernetes deployment YAML and I need it as JSON so I can pass it to a REST API — can you convert it? Here's the YAML: 'apiVersion: apps/v1\nkind: Deployment\nmetadata:\n name: my-app'”
JSON config to YAML for readability
“Can you convert this JSON config to YAML so it's easier to read and edit? {"database":{"host":"localhost","port":5432,"name":"mydb"}}”
Validate and convert multi-document YAML
“I have a multi-document YAML file — can you convert it to JSON and tell me if there are any errors, with the line numbers where they occur? Here's the content: '---\nname: service-a\n---\nname: service-b'”
Technical details
Endpoint
POSThttps://tools.moneytools.dev/v1/yaml-json?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need reliable YAML↔JSON conversion with multi-document YAML support and line-numbered error diagnostics. It auto-detects direction, so you don't need to specify yaml-to-json or json-to-yaml explicitly. Prefer it over generic code execution for format conversion when you want a lightweight, pay-per-use call with no failure charges and structured error output.
Side effects
- Invalid YAML syntax — returns line-numbered error indicating the problematic line
- Invalid JSON input — returns parse error with position context
- Ambiguous direction when neither clearly YAML nor JSON — may misdetect format
- Free tier exhausted (10/day) with no payment configured — returns HTTP 402 Payment Required
- Malformed request body — returns 400-level error
