Shares a payout wallet with 178 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Compare two supplied HTML snapshots and separate markup churn from a content change. Reports markup that changed while the readable content did not, which is a template or build change; the readable lines added and removed; and changes to the title, canonical, robots directive, meta values and declared structured-data types. Content is compared by line presence rather than position, so a reflowed paragraph is not reported as wholly rewritten. Nothing is fetched.

This payout wallet is shared: figures cover all 179 endpoints paid at it, since payments cannot be attributed to one of them. Only payments settled on chains and facilitators we index.
