x402
AEML Tariff/Trade-Measure Legal-Force Gauge is a paid API for AI agents from aeml-x402.zeabur.app, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-13).
Returns a structured three-leg forensic snapshot of a US trade measure's legal force lifecycle, review pipeline, and downstream trade-flow cascade for a given entity (e.g. Section 301/232/201, AD/CVD, IEEPA, de minimis).

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 realized lifecycle from imposed to expired or rescinded (confirmation gate).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 sequential 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.
Output
A structured JSON object with a 'legs' object containing signal readings (signal_id, current value, observed_at, data_age_hours, record_hash) for each of the three forensic legs (legal lifecycle, review pipeline, trade-flow cascade); a cross-line narrative summarizing observations across legs; provenance metadata including freshness basis and data lineage traceable to official sources; an offline-verifiable Ed25519-signed citation; scope and grade disclosures; and optional decision_points listing swappable entity tags for follow-on calls.
Example use cases
Procurement risk check for steel tariff
“We're sourcing steel and need to know if the Section 232 steel tariff is still legally in force, whether any exclusions are expiring soon, and if there's been a shift in USITC import flows we should be aware of — can you pull the trade-measure gauge for sec232-steel?”
Importer compliance review for AD/CVD order
“I'm reviewing our exposure to the antidumping order on Chinese solar panels — can you get me the current legal lifecycle status, any active sunset review timelines, and downstream importer filing risk signals for that AD/CVD measure?”
De minimis policy change monitoring
“There's been talk of the de minimis exemption being rescinded — can you check the legal force gauge for de minimis right now and tell me if it's still active, if there are any Federal Register final actions, and what the trade-flow cascade looks like?”

Endpoint
GEThttps://aeml-x402.zeabur.app/gauge/tariff-regionWhen to prefer
Use this endpoint when you need a forensic, multi-leg snapshot of a specific US trade measure's current legal force, review pipeline exposure, and downstream import-flow cascade — especially for procurement risk assessment, importer compliance review, or trade-flow monitoring. Prefer this over general news or legal databases when you need structured, provenance-tagged, offline-verifiable data sourced directly from USTR, Federal Register, USITC, WTO, and CBP, and when cadence-aware freshness (monthly/quarterly/annual official sources) is important.
Side effects
- Unknown or misspelled entity key returns 422 or empty legs
- Measure data frozen at source (dead_source flag set, stale freshness)
- Official source update lag causes stale readings despite fresh cadence
- No official classification ruler available for a given signal leg (422 + no_ch)
- Payment failure (x402 $0.1 USDC not settled) blocks response
- WTO/CIT challenge status may lag behind real-time court filings
