Pay-per-call compliance data: OFAC sanctions, merchant check, LEI, SEC, WHOIS, FX. x402 in USDC/XRP
Scored across 17 tools
Several tools are near-duplicates: domain_facts and whois both return registrar, creation/expiry, DNS records and SPF/DMARC/DKIM posture, and fx_convert largely duplicates fx_reference_rates (which already supports amount conversion). The KYB cluster is also tangled — counterparty_check and merchant_check bundle overlapping sanctions/LEI/domain facts, while sanctions_screen and sanctions_address are superset/subset of the same check — so an agent can easily pick the wrong bundle versus the single-purpose call.
All names use uniform snake_case and are descriptive resource or action labels (sanctions_screen, lei_lookup, sec_company_facts, us_rates_macro). There is no verb_noun discipline — a few are verbs (verify_receipt, fx_convert) while most are nouns (whois, catalog, health) — but the casing and style are consistent enough to be predictable.
17 tools is on the heavy side for a read-only facts API, and three are free meta tools (catalog, health, verify_receipt) which are justified. However, the overlap between whois/domain_facts and fx_convert/fx_reference_rates means at least two tools do not clearly earn a separate place in the set.
Coverage is broad for a due-diligence/finance data service: FX, macro rates, business days, sanctions (entity and wallet), LEI, SEC fundamentals, domain facts, page rendering, recalls, plus receipts and catalog. Gaps are real but workaroundable: entities-only screening (no individuals), no non-US company registry beyond GLEIF/SEC, and nothing on-chain despite the 'Stablecoin Gateways' name — no chain or stablecoin balance/transaction data.
Business days and public holidays: check if a date is a business day, add or subtract N business days, count business days between dates, or list holidays, for 250 countries, 630 subdivisions (e.g. US-NY, GB-ENG) and 31 stock exchanges, 2025-2030. Use for payment due dates, T+N settlement, delivery estimates and SLAs. Data: python-holidays (MIT). Signed receipt. Price: $0.001 per call via x402 (USDC on Base or XRP on XRPL). The response includes a provenance block (sg-provenance/1): each fact carries its source, source URL, retrieval time and limits; evidence only, no score, rating or verdict. Example arguments: {"calendar":"US-NY","op":"add","date":"2026-12-23","days":"3"}.

Counterparty check (KYB preflight) in one call: give any of a company name, domain, LEI or crypto wallet address (plus an optional EU VAT number), get neutral sourced facts for vendor onboarding and supplier due diligence: sanctions screen of the name on OFAC, EU and UK lists with UN designations flagged, US federal exclusions (SAM.gov debarments and suspensions of firms, by name or UEI), OFAC wallet check, GLEIF LEI match and status, domain age, registrar and email-auth, and an EU VAT number format check. A name screen needs fresh OFAC, EU and UK lists (48 hours each) and returns 503 before payment if any of those is stale. Domain-only, address-only and UEI-only checks do not require the EU or UK lists. No risk score or verdict. Signed receipt. Price: $0.01 per call via x402 (USDC on Base or XRP on XRPL).
