Validate a US bank ABA routing number with the Federal Reserve weighted mod-10 checksum (3-7-1) — not just a 9-digit regex. Returns {valid, routingNumber, district (routing-symbol class), reason}. Catches transposed digits in ACH/wire setup that a length check misses. Structure + checksum only; not a bank-directory existence lookup.

List near-Earth asteroid/comet close approaches to Earth within a date window and maximum distance, from NASA JPL's Close-Approach Data API. Filter by dateMin / dateMax (YYYY-MM-DD) and distMaxAu (max approach distance in AU; default 0.05 AU ≈ 19.5 lunar distances). Each approach: object designation, close-approach date (UTC), nominal + minimum distance in AU and lunar distances, relative velocity (km/s), and absolute magnitude H (a size proxy). Sorted nearest-first. Planetary-defense, observation planning, and "what's passing by this month" queries. Public-domain NASA/JPL data; for full physical/orbital params of a listed object see /api/space/body.

Look up any asteroid or comet in NASA JPL's Small-Body Database by designation, number, or name (e.g. "433", "Eros", "433 Eros", "1P/Halley", "2024 YR4"). Returns full name + kind + orbit class (e.g. Amor, Apollo, Jupiter-family comet), NEO and potentially-hazardous-asteroid flags, physical params (absolute magnitude H, diameter, extent, rotation period, albedo, density, spectral type), and orbital elements (eccentricity, semi-major axis, perihelion/aphelion, inclination, period, Earth MOID, observation arc). Astronomy, planetary-defense, and mission-planning research. Public-domain NASA/JPL data; for a body's near-Earth close approaches see /api/space/close-approaches.

TLD registry intelligence and public-suffix analysis. Mode 1 (tld=io): IANA root-zone metadata — type (generic / country-code / sponsored), managing organization, unicode form for IDN TLDs. Mode 2 (domain=shop.example.co.uk): full Public Suffix List algorithm — the effective public suffix (co.uk), the registrable domain (example.co.uk), the subdomain part, the matched PSL rule, and whether the suffix is ICANN (registry) or private (corporate, e.g. github.io / s3.amazonaws.com) — plus the root-zone metadata for its TLD. Correctly handles wildcard and exception rules and IDN/punycode input. Use for cookie scoping, per-registrant rate limiting, URL dedup, and abuse/phishing analysis. Data: IANA root zone + Mozilla PSL, refreshed weekly.

Normalize and verify drug names against RxNorm, the canonical US drug vocabulary from the NIH. Two modes: term ("tylenol 500mg", brand or generic, typos tolerated) returns ranked RxCUI candidates with normalized names and match scores; rxcui returns the canonical concept (name, term type like IN=ingredient / SBD=branded drug / SCD=clinical drug, suppression flag) plus related concepts — active ingredients, brand names, and available dose forms. Use before writing prescriptions data, drug interactions queries, or pharmacy integrations: verify the drug exists and get its stable identifier instead of trusting model memory. Sibling: /api/medical/icd10 (diagnosis codes). Public-domain NIH data.

Look up or list international treaties transmitted to the US Senate for advice and consent via Congress.gov. Pass congress + number (optionally + suffix for partitioned treaties) to fetch a single treaty with parties, topic, transmittal date, and consideration status. Or list by congress. Returns the congress the treaty was received in, the congress that considered it (if any), partial-treaty suffix, topic, transmitted date, and count of parties.

Stream the latest US Congressional bill summaries via Congress.gov. Each row is a CRS-authored summary attached to a specific version of a bill (Introduced, Reported to House, Engrossed in Senate, Public Law, etc.). Filter by congress + bill type. Returns the underlying bill metadata + summary text + version code + action date. Use this for change-detection on bills you care about, or to power agent-side "what did Congress just pass" feeds.

Resolve any organism by scientific or common name to the GBIF taxonomic backbone — the canonical free reference for life on Earth. Returns the accepted scientific name + canonical name, taxonomic rank and status, the match type/confidence, the full classification (kingdom → phylum → class → order → family → genus → species), up to 8 English vernacular (common) names, the count of recorded occurrences worldwide, and the GBIF species URL. Biodiversity, ecology, education, and as a taxonomy normalizer for other pipelines. Fuzzy-matches misspellings. CC-BY GBIF data.

Validate a European Union VAT number against the official VIES (VAT Information Exchange System) register in real time. Confirms whether the VAT identifier is currently registered for intra-EU trade and, when the member state discloses them, returns the registered business name and address. Covers the 27 EU member states (Greece as EL) plus Northern Ireland (XI); Great Britain (GB) is not in VIES. Pass either a full identifier (vat=DE811569869) or country + number. Returns {valid, countryCode, vatNumber, name, address, requestDate, reason}. When a member-state register is temporarily down, returns a retryable 503 rather than a false negative. Data from the European Commission VIES service.

Sweep a person's name across five US public registries in one call: FINRA securities brokers, federal-court attorneys (CourtListener), federal inmates (BOP), Texas trade licenses (TDLR), and Texas real-estate licenses (TREC). Returns one block per registry with found/error status, match count, and the matching records — name-matched CANDIDATES, deliberately not merged into one identity (same name does not mean same person; verify with each registry's identifier before acting). Due-diligence, KYC screening triage, and background-research staple. Each registry is also a standalone endpoint (/api/license/broker, /api/law/attorney-lookup, /api/gov/inmate-locator, /api/license/trades, /api/license/real-estate) for follow-up by identifier.

Compute the current position of any cataloged Earth-orbiting satellite by NORAD catalog number (e.g. 25544 = ISS, 20580 = Hubble), using fresh Celestrak orbital elements propagated with SGP4. Returns sub-point latitude/longitude, altitude (km), and speed (km/s) for the requested instant (default: now; pass `at` as an ISO timestamp for any time within a few days of the elements' epoch). Supply observer `lat`/`lon` (and optional altKm) to also get look angles — azimuth, elevation, slant range, and whether the satellite is above your horizon — for visual/antenna pointing. Satellite tracking, pass prediction, ground-station planning. Public-domain orbital data; physical/mission metadata is not included.
