Every agent-payable API.

Screen a person or company name against the OFAC SDN and UN Security Council consolidated sanctions lists: fuzzy matching with similarity scores, matched programs, entity type and country. Lists refreshed daily from official sources; screening runs locally — deterministic and fast. A match requires human review; not legal advice.

OFAC SDN sanctions screening for a crypto address or a person/company name. Covers all 963 digital-currency addresses OFAC lists across 19 chains (BTC, ETH, TRX, USDT, SOL, XMR and more) plus 19k sanctioned entities and their aliases. Straight from the US Treasury's own list, refreshed daily.

Checks one crypto address against the OFAC SDN list published by the US Treasury, across 16 currencies including Ethereum, Bitcoin, Tron and USDT. A hit returns the actual list entry - sanctioned entity, its type and its sanctions programmes - not a risk score. Exact matching only, never fuzzy. Every answer carries the publication date of the list snapshot. No API key, no account.

Screen a crypto wallet address against the OFAC SDN sanctions list (US Treasury Specially Designated Nationals) before transacting. Multi-chain across ~20 assets (BTC, ETH, USDT, TRX, XMR and more); EVM 0x addresses match case-insensitively. Returns whether the address is sanctioned plus the listed entity, asset and list publish date. Clean address returns `sanctioned:false`. Public-domain OFAC data.

Sanctions screening of a name against OFAC SDN and Non-SDN, the UN consolidated list, the EU Financial Sanctions File, the UK Sanctions List and Australia's DFAT list. Relevant before transacting with a party, and wherever a sanctions check must be evidenced. Returns listed, mismatch, not_found or unknown, with the matched entry's reference and each list's dates. A near name is never the same party; a list not consulted is named as not consulted. Not advice, not a legal determination.

Sanctions check on who you are about to pay: give the x402 endpoint URL, we read its own 402 quote, pull every payTo (all networks) and screen each against OFAC, UN, EU and UK lists. Signed per-payee and overall verdict: deny on an OFAC match, review on a UN/EU/UK match or an unavailable list, clean otherwise. $0.01 in USDC on Base or Solana. A bad or non-x402 URL returns 400 with charged:false; you are never charged for an error. Free preview: GET /screen-url/preview

Sanctions screening for a person or company: OFAC, EU, UN, UK OFSI, SECO, BIS, World Bank + 125 national lists. Named-source match evidence.

Screen a person or company name against OFAC SDN, UN, EU and UK sanctions lists in one call (fuzzy, aliases). Returns matches with score, list, programs, countries.

Screen a person or company name against the official OFAC SDN list (with aliases), the EU consolidated financial sanctions list and the UN Security Council consolidated list. Fuzzy, word-order independent matching with scores, list, program and aliases. Lists refresh every 12 hours. A screening aid, not a legal determination. Params: name (required), type ('individual' or 'entity', optional), threshold (0.5 to 1, default 0.85), limit (default 10).

Sanctions screening: a name checked against the OFAC SDN and EU FSF lists. Informational signal, not legal advice.

Sanctions screening (AML/KYC) against three official lists in one call: EU (Commission FSF), UN Security Council and UK (HM Treasury OFSI) - 12,000+ entities, 50,000+ name variants, re-indexed daily, fuzzy matching. Each hit states its list, programme, reference and the list date. Optional lists=eu,un,uk.

OFAC sanctions screen for a crypto wallet before you pay it: checks an address (BTC, ETH, USDT, TRX and more) or a person or company name against the US Treasury SDN list, aliases included. Returns a verdict (block on a listed address, review on a name match, pass), each match with SDN ID, programs and match strength, and the list date. A screening aid, not legal advice. Use before paying; full verdict with wallet risk: check_counterparty.

Is this blockchain address on the OFAC SDN list? Screens any address against every Digital Currency Address OFAC publishes (Bitcoin, Ethereum, Tron, USDT, USDC, Monero, Litecoin and more). A match names the sanctioned entity and its SDN id. A miss is reported as 'not on the lists checked, as of this date' and is never a clearance - the answer carries that caveat in the payload. Deterministic: a cached copy of the published list, no model in the path.

Screen a person or company name against the OFAC SDN list. Returns exact and substring matches with the SDN entry id and type, so every hit can be checked against the published list itself. Matching is exact and substring only - never a fuzzy similarity score, because a confident near-miss on a common surname is a liability rather than an answer. A miss is 'not on the lists checked, as of this date', never a clearance.

Screen a person, company, vessel or entity against the EU consolidated financial sanctions list and the US OFAC SDN list, with fuzzy matching of names and aliases, program, type, countries and reference. For KYC/AML before paying or onboarding.

Santorini Sunset — Iconic beauty for reference library and peak aesthetic experience.

Treats cells at or above a caller threshold as foreground, labels four-neighbor connected components, and reports area, bounding box, peak, and mean value. It does not ingest imagery, calibrate backscatter, remove speckle, geolocate pixels, classify objects, or infer real-world meaning.

Before/after satellite comparison of the same area on two dates from NASA GIBS true-color imagery (MODIS or VIIRS, about 250 m per pixel): one side-by-side JPEG with date labels plus pixel-based change metrics (share of changed pixels, brightness change) and a cloud, haze and snow estimate for each date, with a plain-language reading that says whether the change is likely real or just weather.

Daily true-color satellite image of any area from NASA GIBS (MODIS Terra/Aqua or VIIRS, about 250 m per pixel, coastlines overlaid) as base64 JPEG. Useful to see clouds, smoke, snow, floods or fires on a given day. Params: bbox [min_lat, min_lon, max_lat, max_lon] or lat + lon + radius_km (5 to 500, default 50), date (YYYY-MM-DD, default yesterday), layer (modis_terra default, modis_aqua, viirs_snpp, viirs_noaa20), width (64 to 1024, default 512), height (default from aspect).

Satellite Image of Any Place (NASA, daily, true color). Daily NASA satellite image of any place (true color VIIRS/MODIS, or false color), 20-2000 km wide, for any date: verified image URL plus alternate layers. Good for smoke, fires, snow, floods and clouds.

Propagates a circular two-body orbit from altitude, inclination, RAAN, and initial orbital phase; rotates Earth at a fixed sidereal rate; and samples ground-station elevation. It ignores eccentricity, perturbations, epoch-dependent Greenwich angle, refraction, ellipsoid shape, terrain, and antenna masks, so it is a planning estimate rather than operational ephemeris.

The weekly agent-economy series behind Sato Hub's free current-week counts: one row per venue, chain, stage and week, measured from public chain reads. Rows are never summed across venues, chains or stages; null means unknown, never zero. The current week stays free at /api/export/adoption.json.

Daily Sato Score history for one Sato Hub listing: score, tier components, GitHub stars, status and verification state per day, with the dates the score moved (genuine changes vs our own method revisions marked). Captured daily since 2026-06-12; not reconstructable. The current catalog and the daily score line stay free.
