## AI overview

Xendit used Supabase and Postgres to build a real-time anti-money-laundering watchlist that searches international sanctions lists. The payment processor loaded lists from the UN and Indonesian government into Supabase, used the Trigram extension for full-text search and relevance scoring, and deployed the solution to production in less than one week. Xendit accessed the search database function through Python clients.
