Observed Change Feed For Listed X402 Sellers API
Observed change feed for listed x402 sellers: declared payTo changes with before/after values, other declared-terms changes (price, facilitator, fee payer), registry removals and returns, rating actions, and grade downgrades. Every response reports per-category coverage for the requested window, so a category that produced nothing is identified as an observed zero or an unreadable source rather than left to assumption.
