How this service works
Quality-scored paid utility APIs for AI agents over x402 on Base USDC.
Output
Returns a JSON object with a `result.formatted` field containing the input JSON re-serialized with standard 2-space indentation and newlines, making nested structures human-readable.
Example use cases
Readable API response logging
“This API response came back as one long minified line — can you format it with proper indentation so I can read through the structure? Here it is: {"user":{"id":123,"name":"Alice","roles":["admin","editor"]},"status":"active"}”
Debugging compact config file
“I have this compact JSON config and I need to read it carefully to spot a bug — can you pretty-print it for me? {"server":{"host":"localhost","port":8080},"db":{"url":"postgres://localhost/mydb","pool":5}}”
Presenting JSON output in a report
“I need to paste some JSON into a document for my team and it needs to be properly formatted and readable — can you pretty-print this for me: {"results":[{"id":1,"score":0.98},{"id":2,"score":0.75}],"total":2}”
Technical details
Endpoint
POSThttps://agent-utility-network.frosty-sound-4560.workers.dev/v1/paid/json-prettyWhen to prefer
Choose this endpoint when you have a valid but compact or minified JSON string and need it formatted for readability — for display, logging, debugging, or documentation purposes. If your JSON is malformed or broken, use the sibling JSON-repair endpoint first. This endpoint is purpose-built for formatting only and is ideal for agents that need to present structured data in a human-friendly way.
Side effects
- Invalid or malformed JSON input returns an error (for malformed JSON, consider the sibling JSON-repair endpoint first)
- Input exceeding 100,000 characters is rejected
- Empty string input is rejected (minLength: 1)
- Payment failure via x402/Base USDC causes request to be denied
