answers 402

Cross-Verify (CDP-settled mirror) — a neutral check of a public protocol claim (e.g. litcoin, regen) against its own on-chain / API source. Fixed hosts, no redirect follow: we cannot be pointed at an arbitrary target.

We sent a real POST request to this endpoint and it answered 402 with payment requirements we could parse.
