Trimtab US Trade Ledger
ABD ithalatçılarının tarifelerde fiilen ödedikleri — 2017'den bu yana ürün ve menşe bazında aylık resmi gümrük vergisi makbuzları, ayrıca Federal Register atıfları, CBP kararları ve ABD ticaret verileriyle birlikte HTS kural kitabı. Uzaktan erişim, API anahtarı gerekmez.
Dokümantasyon
Give your AI eyes on the physical economy
AI assistants make claims about trade every day — on data they cannot see or verify. Connecting the ledger gives yours the record itself: every US import origin, commodity, gateway and month, and what each of them actually paid at the border, from official receipts. Every number is cross-checked against recorded ship movements and the US Treasury’s own totals, and every number ships with a citation and the test that would prove it wrong. No key, no account, no charge. Your AI does the reasoning; the ledger supplies the record.

What your AI can do once connected
“What did toys from China actually pay in tariffs last year?”→ tariff_burden: monthly duty collected, 2017→now, any origin, any chapter
“What’s the tariff on an upholstered chair from Vietnam?”→ tariff_lookup: statutory rate, every measure in force with its Federal Register citation, and what was actually collected — side by side, disagreeing out loud where they disagree
“What HS code is an electric standing desk?”→ hs_search: candidate codes with hierarchy, rates and CBP ruling counts
“Has CBP ever ruled on a product like mine?”→ rulings_search: classification case law with precedent links
“Show me US furniture imports from Vietnam, monthly.”→ trade_query: the full trade cube — and the ledger tells your AI how to draw it, so the chart looks like this site
13 tools (plus 8 registry/archive sub-tools via the ledger_meta router); every response carries citations, caveats and pointers to the next tool. Tariff answers are records and measurements, not customs or legal advice — duty liability is determined at entry.
