Why this matters — an x402 endpoint that agents paid yesterday can be dead, hijacked (payTo swapped), or quietly repriced today. PulseFeed publishes a dated, anchored record of these changes over time.

For agents — verify before you pay: GET /trust?endpoint=<url> → live validity, on-chain receiver profile, scam flags & a pay/avoid verdict.
Machine-readable feed: /changes.json

Events are derived from PulseFeed's own time-series: every tracked endpoint is probed regularly and we record payTo/price/liveness changes as they happen — data that can't be reconstructed after the fact. High-severity payTo swaps on established receivers may indicate a hijack; rotating receivers (by-design) are marked low. Feed window: 7 days · 2726 total events · generated 2026-09-22T07:30:30.489Z.
