pulsefeed.devThe full MCP supply-chain drift series in one call: every recorded change since 2026-07-30 across the whole registry — ownership swapped, install script added in a later version, repository removed, package unpublished, a removed name republished by someone else. An event exists only because a snapshot from before it does, so this series cannot be rebuilt after the fact. Free feed: last 7 days.

pulsefeed.devIs this x402 endpoint safe to pay? Vet an unknown seller BEFORE paying: pay/avoid verdict, 0-100 trust score, live 402 probe, scam flags (payTo hijack, bait-and-switch pricing, honeypot, wrong asset) and an on-chain check of the receiver on Base. Reads x402 v1 (body) AND v2 (PAYMENT-REQUIRED header) — body-only checkers call live v2 services dead. ?endpoint=url; omit for a trust-ranked catalog.
