POST /v1/rescue

method-gated

Safely repair JSON payloads that fail a known schema. Deterministic repairs only. No semantic guessing. Returns exact change manifest and verifiable receipt. Refuses ambiguous repairs.

Verdict: not verified by an unpaid GET. 405/400: the 402 sits behind the declared method. This says nothing about whether the route works when called as declared.

Try it (unpaid: shows the 402)

curl -si -X POST 'https://ao-payload-rescue-production.up.railway.app/v1/rescue' -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.
