How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
Returns a JSON object with a 'valid' boolean field indicating whether the submitted text is syntactically valid JSON (e.g. {"valid": true} or {"valid": false}).
Example use cases
Pre-flight API payload check
“Before I send this config payload to the server, can you verify it's actually valid JSON? Here it is: '{"host":"db.prod.internal","port":9200,"tls":true}'”
Debugging malformed API response
“I got this response back from a third-party API and my parser is choking on it — can you tell me if it's even valid JSON? Here's the raw text: '{"status":"ok","data":[1,2,3,}'”
Validating user-submitted configuration
“A user just submitted this JSON config in our form — can you confirm it's properly formatted before I save it to the database? Text: '{"theme":"dark","notifications":true,"timeout":60}'”
Technical details
Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/json/validate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, low-cost ($0.001 USDC) programmatic check of JSON validity at runtime — particularly when integrating untrusted or user-submitted JSON, debugging API responses, or gating downstream processing on format correctness. It is well-suited for agents that handle dynamic text inputs and need a cheap validation step before passing data to stricter systems.
Side effects
- Text exceeds 12,000 character limit — request rejected
- Empty or missing 'text' field — validation cannot proceed
- Payment not provided or insufficient — x402 payment required error returned
- Service quota exhausted — bounded execution limit reached
