TRADE EVIDENCE · PAY PER CALL
Get tariff and counterparty evidence in a structured response for your purchasing workflow. No sales call, email handoff, or manual report delivery.
ONE SUPPLIER · ONE TARIFF CODE
Before accepting a supplier quote: compare its General base tariff rate with available USITC evidence, review sanctions-name matches and legal-entity candidates, and keep unresolved checks visible.
Provide the supplier name, HTS code and goods origin. Add customs value and the quoted base rate for an illustrative difference in dollars.
ONE SHIPMENT · COST COMPONENTS
When freight or a quote changes: combine import evidence with the customs value, freight, insurance and fees you supply. Compare a seller quote with the identified cost floor.
This is not a final all-in landed cost. Missing duty evidence stays unresolved. This combined call includes the import evidence; do not buy both for the same task unnecessarily.
One public RDAP check, $0.001 USDC per authorized x402 call. Domain age alone is not proof of legitimacy.
Need more than a domain age? TELAGO Vendor Risk Before Payment combines legal identity candidates, sanctions-name evidence, export-control checks and optional domain context. $0.005 USDC per authorized x402 call. It returns REVIEW when evidence is unresolved; it is not a compliance clearance or proof of supplier identity.
For technical agents that need one quick look-up instead of an import report, TELAGO also offers narrowly priced tools. Use them only when the result is relevant to your task; there is no need to pay for unchanged data again.
The external marketplace paid for one test lookup and observed a response. This is marketplace verification, not evidence of repeat customer purchases. EBEZ operates the TELAGO API; PayAPI Market provides discovery and its own listing verification. Review the live 402 amount and destination in your own x402 client before approving any payment.
A separate existing API checks an invoice against your dated rate card and shipment proofs before payment. $0.05 USDC per authorized audit. Open a free fictional invoice and its review output first. No OCR, automatic invoice approval or promised recovery.
This example is an unpaid request, not a purchase or a verified shipment.

The purchase adapter requires Node.js 22+ and your own configured signer. It is not a browser checkout. Its published instructions distinguish mocked tests from live payment verification. Never share keys or recovery phrases. Reconcile an uncertain payment before retrying.
Call for a new purchase order, supplier, tariff code, origin or revised cost quote. Reuse still-valid evidence when appropriate instead of repeatedly paying for an unchanged request.
