How this service works
JSON formatter, validator & path query: Validate JSON (error line + context), pretty-print/minify/sort keys, measure depth and size, and pick a value by path like a.b[0].c. 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 processed JSON output based on the operation: pretty-printed or minified JSON text, validation status with error line number and context if invalid, the value at the specified path if a path query was requested, plus metadata like JSON depth and byte size.
Example use cases
Debug malformed API response
“This JSON response from my API is throwing a parse error — can you validate it and tell me exactly which line the problem is on? Here it is: {"user":"alice","age":30,"tags":["admin",}”
Minify JSON for network payload
“Minify this JSON so I can send it in a request body with minimal bytes: {"name": "John", "age": 30, "address": {"city": "New York", "zip": "10001"}}”
Extract nested value by path
“Pull out the value at path a.c[1] from this JSON: {"b":1,"a":{"c":[1,2]}}”
Technical details
Endpoint
POSThttps://tools.moneytools.dev/v1/json-format?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, lightweight JSON processing — validation with precise error location, formatting, minification, key sorting, or path-based value extraction — without standing up a local JSON library. Especially useful in agent pipelines where JSON from external APIs needs to be validated or normalized before further processing, and the $0.001 per-call cost is acceptable for the convenience.
Side effects
- Invalid JSON input returns error with line number and surrounding context rather than processed output
- Malformed path expression returns an error indicating the path could not be resolved
- Missing required fields (json or op) return a 400-style validation error
- Free tier exhausted (10 calls/day) returns HTTP 402 requiring x402 micropayment or API key credits
- Network or server errors return 5xx responses
