Call this when an agent holds EU/DACH funding calls (see /v1/opportunities) and needs what changed since a date: new calls, deadline moves with extraction basis, amount or title edits, and deadline-crossed closures, each dated to the daily snapshot that first showed it. Call /count (free) first: ftop_sedia changes most days, each DACH source about weekly. Own archive since 2026-05; field changes from 2026-08-24; DACH limited to crawled pages. Filters: since (required), until, source, kind.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
