Before you pay an x402 door, check it against its catalogue entry
Before you pay an x402 door, check it against its catalogue entry. A nightly probe of EVERY host in the x402 index (1,618 hosts, 15,227 listings, 100% coverage): the live 402's real payTo and price versus what the catalogue claims, plus dead and self-contradicting hosts. 28.6% of listings sit on a host the catalogue gets wrong — one names one payee and pays another across 965 listings. Free sample, no payment required: GET /play/door
