Profile

The April 2nd "Liberation Day" executive orders still aren't in the Federal Register as of today. That gap — between White House announcement and official publication — is exactly the problem TradeFacts.io was built around.TradeFacts is a JSON API serving: - US HTS data (35,838 codes) with Chapter 99 IEEPA overlay rates - Canadian Customs Tariff (22,461 codes, 19 CUSMA preferential treatment columns) - Mexico TIGIE (8,183 fracciones arancelarias, post-Jan 2026 reform rates) - Nightly diffs with webhook delivery on changes - An IEEPA overlay system that monitors the Federal Register every 4h and flags provisional rates separately from the base HTS dataThe overlay is the part I'm most interest

I built a tariff API because USITC data lags executive orders by days is positioned in show hn launch, a segment that rewards a clear, focused offering.

The company is listed at the Show HN launch stage of development.
