POST /repair-json

unprobed

Repair malformed JSON (trailing commas, single quotes, unquoted keys, code fences, truncated output) and optionally validate the result against a supplied JSON Schema. Returns the parsed value, the canonical text, a change log and validation errors.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

curl -si -X POST 'https://x402.fenixfoundry.com/repair-json' -H 'accept: application/json' -H 'content-type: application/json' --data '{}'

The catalog declares POST. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
