Search official US government surplus auction listings -- equipment, vehicles, machinery, scientific equipment, electronics, aircraft, vessels, and other surplus assets -- via the live GSA Auctions API.

GSA Auctions API responses are US federal government works, public domain under 17 U.S.C. Section 105.

Check whether an address already matches its EIP-55 checksum form — call when verifying an address already matches EIP-55 form. Use for chain input hygiene without live RPC—adjacent to OneSource-class small chain reads, but static/local only so rights and margin stay clear. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web se…

Search official product safety recalls and alerts by product or brand keyword, across US FDA (food/drug) and UK OPSS (general product safety) -- the same already-cleared sources composed inside merchant-trust-check-v1, exposed here as a standalone product for use outside a merchant-domain context (e.g. checking a specific product name). EU Safety Gate non-food product alert data is licensed for inclusion (CC BY 4.0) but not yet technically integrated pending a documented access path.

Live Legal Entity Identifier (LEI) lookup via GLEIF's public API: legal name, entity status, jurisdiction, and registration status. GLEIF LEI reference data is published under CC0 1.0 Universal -- commercial reuse, including paid API resale, is explicitly permitted with no attribution requirement.

Checks whether a domain appears technically configured for email delivery, from direct public DNS records only: MX presence, SPF presence, DMARC presence and policy, and an optional DKIM selector check. Queries DNS over HTTPS against a public resolver -- no test emails sent, no mailbox existence verification, no personal data, no leaked-email databases, no proprietary deliverability dataset.

Search live drug and medicine metadata from the U.S. FDA's openFDA API: brand/generic name, active ingredients with strength, dosage form, route, manufacturer/labeler, product type, marketing status, and NDC codes -- plus an optional short (~400 character) label excerpt (purpose or indications only) and an optional recall/enforcement flag. Composed entirely from openFDA's NDC Directory, Drug Label, and Drug Enforcement APIs, all public domain (CC0 1.0 Universal). Never returns full label section

Cross-references a UK haulage operator's DVSA-declared licence holder name against that company's real, live Companies House officers and persons with significant control (PSC) -- flagging a mismatch, or a recent director/PSC change, the real pattern seen in distressed-acquisition cargo-theft fraud where a haulier's licence still shows the old, legitimate operator while control of the company has quietly changed hands.

Compare a bounded passage in the public-domain BSB and WEB without blending or interpreting the source texts.

Search live UK/EU public procurement tenders and US federal grant opportunities in one call: UK Contracts Finder, UK Find a Tender Service, EU TED (Tenders Electronic Daily), and Grants.gov. Returns source-linked metadata only -- title, buyer/funder, deadline, value, region, category codes, and a link to the original notice -- never full tender documents, specifications, or application forms. Grants.gov is queried live per-request and is never bulk-cached or resold as a stored dataset.
