How this service works

x402-paid inference + audit endpoints

Output

Returns a JSON object indicating whether the submitted payload is valid JSON, along with error details such as position and description of any syntax issues if validation fails

Example use cases

Pre-flight API payload check

“Before I send this config object to the database API, can you validate that it's actually valid JSON? Here it is: '{"host":"db.example.com","port":5432,"ssl":true}'”

Debugging malformed webhook data

“I'm getting errors processing incoming webhooks — can you check if this payload is valid JSON and tell me where the syntax problem is: '{"event":"purchase","amount":99.99,"user_id":42,}'”

User-submitted form data validation

“A user submitted this as JSON configuration in our app — can you validate it's well-formed before we store it? The string is: '{"theme":"dark","notifications":true,"language":"en"}'”

Endpoint

GEThttps://apex-edge.pearceshrader.workers.dev/api/v1/util/json-validate?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need a lightweight, pay-per-call JSON syntax validation check without standing up your own parser or validator, especially within an x402-payment-enabled agentic workflow where micro-cost API calls are acceptable

Side effects

Empty body submitted — returns validation error or 400
Non-JSON content type mismatch causing parse failure before validation
Oversized payload exceeding worker request limits — returns 413 or timeout
Payment not included or insufficient — returns 402 Payment Required
Malformed request envelope (not the JSON being tested) — may return 400
