How this service works
200 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.
Output
A JSON object containing a 'data' field with the converted JSON representation of the input YAML, plus metadata fields like 'live' (boolean), 'name' (service name), and 'price' (cost per call).
Example use cases
Config file format migration
“I have this Kubernetes deployment YAML and I need it as JSON so I can feed it into a REST API that only accepts JSON — can you convert it? Here's the YAML: 'apiVersion: apps/v1\nkind: Deployment\nmetadata:\n name: my-app'”
OpenAPI spec format switch
“My OpenAPI spec is in YAML but the tool I'm integrating with only reads JSON. Can you convert this YAML snippet to JSON? 'openapi: 3.0.0\ninfo:\n title: My API\n version: 1.0.0'”
CI pipeline data transformation
“I'm getting YAML output from a GitHub Actions workflow and need to pass it as JSON to a downstream service. Convert this YAML for me: 'status: success\nbranch: main\ncommit: abc123'”
