Repair malformed JSON from model or tool output using deterministic CPU rules
Repair malformed JSON from model or tool output using deterministic CPU rules. Returns parsed value, repaired JSON text and a changed flag. Send JSON {text:string}. Paid calls require a fresh secret random 32-byte base64url Idempotency-Key; reuse it only for retries of the same input. Maximum request body: 128 KiB. Repair may change meaning; validate the result.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
