How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

Output

Returns a JSON object with an 'ok' boolean indicating success and a 'paid' boolean confirming the x402 micropayment was accepted, along with the formatted or validated JSON output.

Example use cases

Pretty-print minified JSON schema

“I have this compact JSON schema and I need it formatted cleanly — can you pretty-print it? Here it is: '{"type":"object","properties":{"age":{"type":"integer"},"email":{"type":"string"}}}'”

Validate JSON schema before API submission

“Before I submit this JSON schema to my API, can you check if it's valid and properly formatted? Schema: '{"type":"array","items":{"type":"string"}}'”

Normalize JSON for code review

“Can you normalize and reformat this raw JSON string so my team can review it more easily? Here's the input: '{"id":1,"data":{"x":true,"y":null}}'”

When to prefer

Side effects

Invalid or malformed JSON schema string returns a parse error
Missing 'schema' parameter may return a bad request or empty response
x402 payment failure results in 402 Payment Required with no data returned
Extremely large schema strings may time out on the Cloudflare Worker edge
