POST /v1/transcode

live

Decode a base64 byte buffer from one character set and re-encode it into another (utf-8, utf-16le, utf-16be, latin1, ascii). Characters that the target set cannot represent, or bytes invalid for the source set, are clean 400s.

Verdict: live. The unpaid GET reached a valid 402 (confirmed by the re-probe of 2026-10-01).

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.
