How this service works
Pretty-print JSON. Call before showing configs to humans or attaching readable debug dumps. Returns indented JSON text; invalid JSON returns a structured error. $0.001 USDC per successful call via x402 on Base—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.
Output
Returns the input JSON reformatted with standard indentation and newlines, making it human-readable. If the input is not valid JSON, returns a structured error object describing the parse failure rather than throwing an exception.
Example use cases
Display config to end user
“I need to show this config JSON to the user in a readable way — can you pretty-print it before rendering it in the UI? Here's the raw string: {"host":"localhost","port":5432,"db":"myapp"}”
Attach readable debug dump
“Before I attach this API response to the debug log, can you reformat it with proper indentation so engineers can read it? The JSON is: {"status":"ok","data":{"id":42,"items":[1,2,3]}}”
Validate and inspect unknown JSON
“I got this JSON blob from a webhook and I'm not sure if it's valid — can you pretty-print it so I can inspect the structure? Here it is: {"event":"purchase","amount":99.99,"currency":"USD"}”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/json-prettyWhen to prefer
Choose this endpoint when you need a deterministic, first-party JSON formatter with no API key or subscription requirements, billed only on success via x402 micropayment. Ideal for agents that need to pretty-print configs, API responses, or debug dumps before presenting them to humans, especially in pipelines where a lightweight pay-per-use formatter is preferable to bundling a local JSON library.
Side effects
- Invalid JSON input returns a structured error response (not an HTTP error), with details about the parse failure
- Malformed or empty json_text field may return a validation error
- Network or payment failure via x402 may prevent the call from completing
