How this service works
Check whether text is strict JSON: send a string and get valid true/false, the value type, and parse diagnostics when it fails. Use it as a cheap gate before storing or forwarding JSON. $0.001 USDC per call on Base.
Output
Returns deterministic parse diagnostics: whether the input is valid strict JSON, and if not, details about the specific parse error including position, line number, and a description of what went wrong.
Example use cases
Debug malformed API payload
“I'm getting a JSON parse error when submitting this payload — can you validate it and tell me exactly which line or position has the problem: '{"user":{"id":42,"email":"test@example.com","roles":["admin","editor"]}'?”
Pre-flight check before database insert
“Before I store this config blob, can you confirm it's valid strict JSON? Here it is: '{"timeout":5000,"retries":3,"endpoints":["https://a.example.com","https://b.example.com"]}'”
Validate user-submitted JSON in automation
“A user just submitted this JSON form response — check if it parses correctly as strict JSON and give me any error diagnostics: '{"firstName":"Jane","lastName":"Doe","preferences":{"theme":"dark","notifications":true,}}'”
Technical details
Endpoint
POSThttps://api.avedaris.com/v1/paid/json-validate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need deterministic, exact parse diagnostics for a JSON string — especially when debugging malformed JSON, validating user-submitted payloads before processing, or building automated pipelines that need precise error positions. Prefer this over client-side JSON.parse() when you need structured, machine-readable diagnostics with consistent error reporting regardless of runtime environment.
Side effects
- Empty input string rejected (minLength:1 constraint)
- Input exceeding 100,000 characters rejected (maxLength constraint)
- Non-string body field causes schema validation failure
- Malformed request body returns 4xx error
- Transient network or server error returns 5xx
