KYB at onboarding only tells you what a counterparty looked like on signup day. Prometiam adds continuous post-onboarding monitoring: a daily query of official-gazette feeds — BORME (Spain), BODACC (France) and UK Companies House — normalized into one typed-event schema across countries. One cron, one endpoint, predictable cost, versus annual batch-FTP subscriptions from legacy vendors.
Two endpoints power the flow, and both are company-scoped: /company-events/search returns events for a named counterparty since a given date, and /company-events/timeline pulls that company's full lifecycle. There is no un-scoped whole-gazette query, so the operational shape is a daily cron that walks your own watchlist, passing each counterparty plus date_from set to your last sweep. For a version you do not schedule yourself, POST /monitor subscribes a company and pushes signed webhooks instead.
Each event carries previous and new values where applicable, plus a link to the original gazette PDF for audit.
BORME and BODACC are ingested within hours of publication; UK is monthly bulk plus daily delta. Webhooks are live: POST /monitor with a webhook_url and alerts arrive HMAC-SHA256 signed (X-Prometiam-Signature) for Spain, Ireland and Poland. For the other countries the pattern is daily cron plus diff. A 1,000-counterparty portfolio fits the Starter tier; 5,000 fits Professional, with sanctions screening (6 sources, 44,000+ active entities) included.
