How this service works
[3-LEG] Tariff and customs measure chain, one trade measure (?entity=sec301-china-list1): leading review pipeline stage -> current current legal force -> realized lifecycle from imposed to expired or rescinded (confirmation gate). A chain, not one reading: confidence = how many legs are lit, in order. Sources: USTR, Federal Register, USITC. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. $0.25 per call.
Output
A JSON object containing three sequential chain legs: (1) leading review pipeline stage indicating early-warning signals, (2) current legal force status of the tariff measure, and (3) realized lifecycle status (imposed, expired, or rescinded). Also includes a confidence score reflecting how many legs returned valid data, sourced from USTR, Federal Register, and USITC. Returns 422 with no charge if no data is available for the requested entity.
Example use cases
Import compliance tariff status check
“I'm importing steel from a non-exempt country — can you check the current legal force status and lifecycle stage of the Section 232 steel tariff so I know if it's still active?”
EV manufacturer trade policy monitoring
“We make EVs and need to know if the Section 301 EV tariff modifications are still in the review pipeline or have been finalized — can you pull the full 3-leg chain for sec301-ev-modifications?”
Trade analyst tariff lifecycle audit
“I'm writing a report on U.S.-China trade actions — can you get me the full measure chain for Section 301 China List 3, including leading review signals, current legal status, and whether it's been rescinded or is still imposed?”
Technical details
Endpoint
GEThttps://api.truthbear.co/gauge/tariff-regionWhen to prefer
Choose this endpoint when you need a structured, multi-stage status view of a specific U.S. tariff or trade measure — specifically its review pipeline position, active legal force, and historical lifecycle. It is best suited for compliance checks, trade policy monitoring, and regulatory research involving USTR Section 301 or Section 232 actions. Prefer it over generic news or search APIs when you need authoritative, source-attributed (USTR/Federal Register/USITC) chain-of-status data for a known, catalogued trade measure entity.
Side effects
- 422 no_charge — no data available for the requested entity ID; not billed
- Invalid or unrecognized entity ID — may return empty or error response
- Entity ID not in the supported set of 22 monitored objects — use GET /gauge/catalog to verify
- Partial confidence — one or more legs may have no current data, lowering the confidence score
