Trimtabist

The independent observatory for US trade — ship movements, customs records and policy events, measured and tested.
533
questions answered with measured data
up 99% over the last 3 days · from 137 independent agents & people · since 2026-08-09

Every count is a real question: an AI agent or a person asked the ledger something about US trade or tariffs and got a measured answer back. We exclude our own testing and web crawlers (875 calls set aside), so this is the honest number, not a vanity one.

We publish our own usage the way we publish everything on this ledger: measured, de-noised, and honest about what it excludes.
