Show HN: Tradefacts.io – JSON API for US/Canada tariff data as trade war heats

I built this because I kept seeing the same problem: customs brokerage and trade compliance software teams maintaining scrapers against USITC or downloading CSV dumps manually — then scrambling every time the tariff schedule changed.
The US HTS schedule has 32,295 records. Canada's Customs Tariff has 22,461. Both are updated on an ongoing basis from official sources (USITC REST API and CBSA releases). With Section 232 actions accelerating and US-Canada tariffs actively moving right now, "we'll update it next sprint" is no longer an option for teams whose customers care about duty rates.
TradeFacts ingests both schedules nightly, diffs every record, and serves it as clean JSON. Three endpoints: lookup by code, keyword search, and changes since last update. Auth is one header. No scraping, no schema surprises.
$199/mo. 30-day free trial, no credit card. Happy to answer questions about the data pipeline or the USITC API quirks — there are a few.
What are the sharp edges if someone wanted to do this themselves? I assume there are official sources for this data but it's not trivial to "throw my agent at it".
