API access

What would actually be sold: every response carries a published error band — a duty range with its national-line spread stated — plus per-number source, licence and observation date. No duty-rate API we have verified publishes either.

6-digit ceiling. Responses stop at the HS6 heading. The 8–10 digit national line — the legally binding layer — is customs business for a licensed broker, and this API will never emit it.
Ranges, never points. You get a duty range with the spread stated, never a single figure pretending to be exact.

If either limitation is a dealbreaker, the honest answer to the question below is “No” — and that answer is just as useful to us.

Would you use it — at that price?
