Fetch the authoritative current text of any United States Code section by title and section number — for example title 17, section 107 returns the fair-use statute. Returns the canonical citation, heading, hierarchy context (title/chapter), full statutory plain text, the Statutes-at-Large source credit, and a link to the official OLRC page; set includeNotes=true to also get editorial notes (amendment history, effective dates). Hyphenated and lettered sections like 1395w-4 or 78j work. Data from the Office of the Law Revision Counsel current ("prelim") edition, public domain — verify statutory citations against the authoritative source instead of relying on model memory. For federal regulations see /api/law/cfr-section; for case law see /api/law/case-verify.

FINRA BrokerCheck lookup — every US registered broker / investment advisor (~620k current + former). Search by free-text query (name + firm) or by CRD number for a direct individual record.

US Coast Guard activity / port-state-control case history for a vessel, by USCG vessel id (from maritime.vessel). Returns cases newest-first with the activity id, start date, type (Boarding, Inspection, Investigation, etc.), and process status. Keyless, public-domain. The compliance/inspection record behind a vessel — use for safety and counterparty due diligence.

Look up world ports and terminals in the NGA World Port Index (Pub 150, ~2,950 ports) by port name (partial match) and/or country (full country name, e.g. "Japan"). Returns matching ports with location (lat/lon, country, region), UN/LOCODE, harbor size/type and shelter, max vessel length/draft (meters), channel/anchorage/cargo-pier depths, tidal range, and chart number. Keyless, public-domain (NGA). Physical-port reference data an LLM cannot reliably recall; complements maritime.vessel (USCG vessel registry) and maritime.cases (port-state-control inspections).

Look up vessels in the US Coast Guard PSIX registry by name (partial match), call sign, official number, hull number (HIN), flag country, service type, or build year. Returns matching vessels with the USCG vessel id, name, call sign, service type, build year, status, official number, HIN, and flag. Keyless, public-domain. Covers US-flagged vessels (and foreign vessels with US port-state-control activity). Pair the returned vesselId with maritime.cases for the inspection record. (Cross-references trade.locode for ports.)

Stock-exchange holiday calendar. Pass exchange (default US); returns the list of upcoming market holidays with the date, holiday name, whether the session is a full close or an early close, and the trading hours when partial. Use it to plan around non-trading days. Data by Finnhub.

Is a stock exchange open right now? Pass exchange (default US); returns whether trading is open, the current session (pre-market, regular, post-market, or closed), whether today is a market holiday, the exchange timezone, and the server timestamp. Use it to gate time-sensitive logic to market hours. Data by Finnhub.

FDA 510(k) premarket clearances — the record of medical devices cleared for US marketing by demonstrating substantial equivalence to a predicate device. Search by device name, applicant (manufacturer), or FDA product code, and get back each clearance with its K-number, device name, applicant, decision date and decision description, clearance type (traditional/special/abbreviated), product code, advisory committee, and date received — newest decision first. Free, public-domain US government data. Authoritative regulatory-status data for medical-device diligence; point-in-time public records, not regulatory advice.

FDA medical device classification — the regulatory class and controls for a device type. Search by device name or FDA product code and get back the device class (I/II/III, mapping to regulatory risk and controls), CFR regulation number, medical specialty/review panel, the official definition, and flags for life-sustaining/supporting, implant, GMP-exempt, and third-party-review eligibility. Free, public-domain US government data. The authoritative answer to "what FDA class is this device and what regulation governs it" — for regulatory and medical-device diligence; point-in-time public records, not regulatory advice.

FDA GUDID (Global Unique Device Identification Database) lookup — identify a marketed medical device from its UDI or by brand/company. Search by UDI/device identifier, brand name, or company name and get back the device description, version/model number, prescription vs OTC, single-use/kit/combination-product flags, MRI safety, sterilization, commercial-distribution status, publish date, the device identifiers (with issuing agency — GS1/HIBCC/ICCBBA), FDA product codes, and GMDN terms. Free, public-domain US government data. The canonical "what device is this UDI" lookup for supply-chain, clinical, and recall-matching agents; point-in-time public records.

FDA drug approval history from Drugs@FDA — the official record of FDA-approved drug applications. Give a drug name (brand or generic), an FDA application number (e.g. NDA021436), or a sponsor name, and get back each application with its products (brand name, active ingredients + strengths, dosage form, route, marketing status, therapeutic-equivalence code, reference-drug flag) and its full submission history (original approvals, supplements, status + status date, review priority). Free, public-domain US government data. The authoritative "is this drug FDA-approved, by whom, when, and in what formulations" record — point-in-time public records, not medical advice.

Authoritative FDA drug label (Structured Product Labeling). Give a drug name (brand, generic, or substance), or an exact NDC, RxCUI, or SPL set_id, and get back the FDA-approved label split into the sections agents need: boxed warning, indications and usage, dosage and administration, contraindications, warnings, adverse reactions, drug interactions, use in specific populations, pregnancy, mechanism of action, and active/inactive ingredients. Each record also carries identity metadata (brand/generic names, manufacturer, NDCs, RxCUIs, route, DEA schedule, OTC vs prescription) plus a hasBoxedWarning flag. Free, public-domain US government data. Point-in-time public records, not medical advice. Use for prescribing-support, pharmacy, and clinical agents that must read the real label rather than guess it.

Look up US drug pricing from CMS NADAC (National Average Drug Acquisition Cost) — the benchmark per-unit acquisition cost CMS surveys from retail pharmacies and publishes weekly. Pass ndc (11-digit National Drug Code) for an exact product, or name (drug name/description keyword, e.g. 'atorvastatin 10 mg') to search. Returns rows with the NDC, description, nadacPerUnit (USD per pricing unit), pricingUnit (EA/ML/GM), effectiveDate, OTC flag, and brand/generic classification — most recent effective date first. Real surveyed acquisition costs instead of model-guessed prices. Public domain; the current-year dataset is resolved automatically. NADAC is an acquisition-cost benchmark, not a retail or insured price.

One-call drug situational awareness. Give a drug name (resolved to a canonical RxCUI via NIH RxNorm), or an exact rxcui or ndc you already hold, and get back: whether it is currently in FDA shortage, any open or recent FDA recalls, and FDA NDC-directory metadata (labeler, DEA schedule, pharmaceutical class, marketing status). Returns a resolved identity block plus hasCurrentShortage / hasOpenRecall booleans and one found/error block per source (shortages, ndc, recalls). Composition of NIH RxNorm + OpenFDA drug-shortages, NDC directory, and recall enforcement — all free, public-domain US government data; each source degrades independently. Point-in-time public records, not medical advice. Use for pharmacy/supply-chain triage, prescribing-support agents, and verifying a drug is real, scheduled, and available before acting.

MedlinePlus Genetics (US National Library of Medicine) reference on a genetic condition or gene. Give a term (e.g. "cystic fibrosis", "BRCA1", "sickle cell") and get back the authoritative NLM record: the condition/gene name, a plain-language summary, the full set of sections (description, causes, frequency, inheritance, treatment), the inheritance pattern(s), related genes (with links), synonyms, and cross-references to other databases (OMIM, GTR, ICD-10-CM, …). Free, public-domain (NLM). Authoritative genetics reference an LLM cannot recite reliably — for clinical, patient-education, and research agents. Educational reference, not medical advice.

Verify and search ICD-10-CM diagnosis codes against the official US code set (FY2026, ~98k entries). Pass code (with or without the dot, e.g. E11.9 or E119) to confirm the code exists and list its more-specific child codes, or q to keyword-search code descriptions (e.g. "type 2 diabetes neuropathy"). Optional billable_only=true restricts results to codes valid for claim submission; limit caps results (1-50, default 10). Returns a verified flag, the exact match if any, and matched codes with billable status plus short and long descriptions. Data: CMS/NCHS ICD-10-CM (public domain), refreshed each US fiscal year. Use to confirm diagnosis codes are real and current before placing them in claims, prior authorizations, or clinical documents.

Look up US healthcare providers in the CMS NPPES registry — the authoritative directory of National Provider Identifiers (NPIs). Give an exact 10-digit NPI, or search by provider last name (+ optional first name), or organization name, optionally narrowed by state and taxonomy/specialty. Returns each provider with NPI, entity type (individual vs organization), status, name/credential/gender or organization name, sole-proprietor flag, enumeration + last-updated dates, primary taxonomy, the full taxonomy list (code, description, primary flag, state license), and practice/mailing addresses with phone. Free, public-domain (CMS). The canonical "who is this NPI / find this provider" lookup for healthcare, claims, and credentialing agents.

Resolve a 10-digit NPI to the provider identity plus a fully decoded specialty profile in one call: entity type, name/organization, status, the primary specialty (NUCC grouping + classification + display name), and every taxonomy on the record decoded the same way -- with primary flag, practice state, and license. Combines the NPPES lookup (medical.npi) with the NUCC specialty decode (medical.taxonomy-specialty) so a claims, credentialing, or referral agent gets "who is this NPI and what do they actually do" without a second call. Data: CMS NPPES + NUCC (US public domain). Note: the facility CCN (CMS Certification Number) requires a separate CMS enrollment crosswalk and is returned null (DEFERRED) rather than guessed.

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.

Resolve a NUCC Health Care Provider Taxonomy code -- the specialty code returned by medical.npi and printed on every NPPES record -- into its human specialty: grouping (top level, e.g. "Allopathic & Osteopathic Physicians"), classification (e.g. "Anesthesiology"), specialization, the official display name, and the section (Individual vs Non-Individual). The decode step every claims, credentialing, and provider-directory agent needs to turn an opaque 10-char taxonomy code into a readable specialty. Data: NUCC code set (public domain), bundled and version-pinned. Note: the CMS Medicare 2-char physician-specialty crosswalk is published only as a PDF, so medicareSpecialty is returned null (DEFERRED) rather than guessed.

Resolve a music artist from MusicBrainz (CC0). Pass a name (or free-text/Lucene query). Returns ranked artists with MusicBrainz ID (MBID), name, sort name, type (Person/Group), country, gender, life span (begin/end/ended), and disambiguation. Keyless, public-domain core data. Use to canonicalize an artist to its MBID.

Resolve a song/recording from MusicBrainz (the open, CC0 music encyclopedia). Pass artist + title, or a free-text query (Lucene supported). Returns ranked recordings with MusicBrainz ID (MBID), title, primary artist, length (ms), first-release date, and disambiguation. Keyless, public-domain core data. Use to canonicalize a track to its MBID or cross-reference identity.

Resolve an album/release from MusicBrainz (CC0). Pass a barcode (UPC/EAN), or artist + album, or a free-text query. Returns ranked releases with MusicBrainz ID (MBID), title, primary artist, release date, country, barcode, status, track count, label, and catalog number. Keyless, public-domain core data. Barcode → album is the differentiated lookup (resolve a physical product to its metadata).

Look up an Autonomous System (BGP) by AS number. Pass asn as AS3333 or 3333. Returns the AS holder/operator name, the IANA/RIR allocation block it falls in, whether it is currently announced, and a live routing-status block: first/last seen prefixes, announced IPv4/IPv6 prefix + address counts, RIS peer visibility, and observed BGP neighbour count. Data: RIPEstat (RIPE NCC), free and public. Distinct from geo.ip (host geolocation) and dns/whois (name lookups) — this is who-owns-and-routes-this-AS, observed live from the global routing table. For network forensics, abuse/security triage, and infrastructure mapping.

Resolve a single IPv4/IPv6 address to its full network identity in one call: the Autonomous System number, the authoritative AS holder/operator (RIPEstat), the ISP + organization, whether the AS is currently announced, the RIR/IANA allocation block the AS sits in, and country/region/city + coordinates + timezone. One join that turns an IP into "who runs this network and where" -- the lookup network-forensics, abuse triage, and fraud agents otherwise stitch together from a geo API plus a separate BGP source. Composes geo IP data + RIPEstat (RIPE NCC, CC BY 4.0); the routing/holder block degrades independently, with per-source status returned. Distinct from net.asn (AS-number first) and geo.ip (geo only): this is IP-first and joins both.

Resolve a MAC address (or bare OUI prefix) to its IEEE-registered hardware vendor. Accepts any common format — FC:FB:FB:01:02:03, fc-fb-fb-01-02-03, fcfb.fb01.0203, fcfbfb, or a 9-hex MA-S prefix. Uses longest-prefix matching across the IEEE MA-L (24-bit), MA-M (28-bit) and MA-S (36-bit) registries so blocks IEEE has subdivided resolve to the actual manufacturer. Returns the vendor name, the matched OUI prefix and which registry it came from, plus decoded address bits: whether the address is multicast/group, locally administered, or a randomized (privacy) MAC — for which no vendor exists by design. Authoritative bundled IEEE data.

RPKI Route Origin Validation for a (BGP origin AS, prefix) pair — answers whether an AS is legitimately authorized to originate a prefix. Pass asn (e.g. AS15169) and prefix (CIDR, e.g. 8.8.8.0/24). Returns status (valid = a ROA authorizes it; invalid = a ROA exists but does NOT authorize this origin — a possible hijack/route-leak that RPKI-enforcing networks will drop; unknown = no covering ROA), a hijackSignal boolean, the validating ROAs (origin, prefix, maxLength), and a plain-English description. Live RIR/RPKI data via RIPEstat (keyless) — un-derivable by an LLM. The core BGP-security check; complements net.asn.

Supports count (1-20), offset, country (2-letter), and freshness (pd=past day, pw=past week, pm=past month, py=past year). Use for current events, market-moving developments, monitoring, and "what happened with X" questions. For general web results see /api/search/web; for Hacker News specifically see /api/news/hn-top.

Look up US 501(c) nonprofits and screen each result against the OFAC sanctions list in one call. Pass q (organization name) or ein; each matched organization returns its registry record (EIN, name, location, NTEE code, subsection) plus a sanctions block — flagged status, match count, and the matching SDN entries with confidence scores. Grant-making due diligence, donation compliance, and charity-fraud triage. Components also standalone: /api/nonprofit/search (registry only) and /api/law/sanctions-check (screen any name). Same composition family as /api/business/entity-screen.

US 501(c) nonprofit organization search. Lookup by 9-digit EIN (with or without hyphen), free-text name, 2-letter state, NTEE category code (e.g. 'B99' for education), or IRS subsection code (3 = 501(c)(3), 4 = 501(c)(4), etc.). Each record includes EIN, name, city/state, NTEE code, subsection code + human-readable subsection description (e.g. '501(c)(3) Charitable / Religious / Educational'), and relevance score. Sourced from ProPublica Nonprofit Explorer, which aggregates IRS Form 990 + BMF data; underlying IRS data is public domain.

USDA FoodData Central nutrition lookup. Two modes: search (query=cheddar cheese) returns matching foods with fdcId, description, data type, category, and brand; detail (fdcId=328637) returns the full analyzed nutrient profile — energy, protein, fats, carbohydrates, vitamins, minerals — with USDA nutrient numbers, amounts, and units (per 100 g/ml unless serving fields indicate otherwise), plus ingredients for branded foods. Filter search by dataType: Foundation and SR Legacy are lab-analyzed generic foods, Branded is the packaged-food label corpus, Survey (FNDDS) is as-consumed dishes. Authoritative USDA data covering ~400k foods — use real analyzed values instead of model-estimated nutrition facts.

Full occupation dossier from O*NET (US DOL) by SOC / O*NET-SOC code (e.g. 15-1252 or 15-1252.00). Returns title, description, bright-outlook flag, sample reported job titles, and the top skills, knowledge areas, abilities, work tasks, and technology skills/tools.

Returns a flat array of papers with stable schema: source, sourceId, doi, title, authors, abstract, year, publishedAt, citationCount, url, pdfUrl. Partial failures surface in the errors array rather than failing the whole call. Optional filters: since (YYYY-MM-DD), sources (subset), limit (max 20 per source).

Unified read API over US National Park Service developer.nps.gov. Pick a resource: parks (every NPS unit — historical parks, monuments, seashores, etc.), alerts (closures, dangers, info), campgrounds (NPS-operated campgrounds with reservation links), events (talks, walks, ranger programs), newsreleases (park news), thingstodo (activities by park), visitorcenters. Filter by parkCode (CSV — e.g. "acad,yose,grca"), state, or free-text query. Returns the upstream NPS payload verbatim (rich nested objects with images, addresses, operating hours, etc.).

Full US patent application file-wrapper detail by application number.
