Seller Monitoring

Weekly payTo-drift reports for x402 sellers.
We don't just list endpoints. We verify who actually receives the money.

The problem we found first

~91.5% of the paid x402 economy fails to settle and deliver (RobotsShop paid verification sweep, in index as of 2026-08-23). The failure buyers can't see at all: wallet drift — an endpoint whose directory listing advertises one payment wallet while its live 402 response demands payment at another.

Case in point, from our public index data:

Two wallet rotations across 965 endpoints in ~7 days while the directory kept advertising the original address. Full case study with probe-level evidence: demo case study #1.

Counts are "in index as of" their snapshot dates. A missing snapshot day is not evidence of no-drift. That's the standard we hold ourselves to.
