INPADOC legal-status events for a patent publication via EPO OPS: the timeline of procedural events (examination, grant, designations, national-phase entries, lapses, withdrawals) each with an event code, description, and date. For tracking whether a patent is in force, granted, or lapsed. Net-new.

Search currently-active FARA (Foreign Agents Registration Act) registrants by name. Pass a company or person name; returns whether the entity is a registered foreign agent (isRegisteredForeignAgent), a single KYB-safe bestMatch (null below medium confidence — no false positives), and scored candidate matches with registration number, registration date, city/state, and a 0-1 match score + confidence (high/medium/low). FARA registration is a US disclosure status (an agent acting for a foreign principal), not wrongdoing. Authoritative DOJ FARA eFile data, free and keyless — the foreign-agent check a compliance or procurement agent cannot derive from training.

List every document in the file wrapper for a US patent application. Returns each document with its USPTO code (e.g. CTNF non-final OA, CTFR final OA, IDS, WCLM claims worksheet, NOA notice of allowance), human-readable description, official date, direction (INTERNAL/INCOMING/OUTGOING), and available formats with page counts. Includes patentCenterUrl pointing at the public USPTO Patent Center documents page for direct PDF download. Application number is the 6-10 digit USPTO ID.

Look up entities registered to do business with the US federal government in SAM.gov. Search by ueiSAM (12-char Unique Entity ID), cageCode, or legalBusinessName (provide at least one); page with limit (1-100). Returns each entity with its UEI, CAGE code, legal and DBA name, SAM registration status and dates (registration, expiration, last update), purpose of registration, an active-exclusion flag, physical address, and business types — plus a total match count. Data: SAM.gov entity management, free and public-domain (registration core data; sensitive FOUO sections are not returned). The canonical federal counterparty identity key — pair with /api/gov/exclusions (debarment) and /api/law/sanctions-check (OFAC) for full counterparty due diligence.

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.

Search US patent applications and grants via the USPTO Open Data Portal. Query: q (required, 2+ chars), yearFrom / yearTo (optional filing-year bounds), applicationType (optional: Utility|Design|Plant|Reissue), limit (1-100, default 10), offset (0-based, default 0). Returns { total, returned, offset, limit, hits[{ applicationNumber, title, applicationType, firstInventor, inventors[], applicants[], filingDate, effectiveFilingDate, status:{ code, description, updatedAt }, cpcSymbols[], uspcSymbol, url }] }. URLs link to USPTO Patent Center for the public file wrapper.

Official US EPA/DOE fuel-economy, fuel-cost, and emissions data for a vehicle by year + make + model. Because a model-year often has several powertrain configurations (engine/transmission), this returns one entry per configuration, each with: MPG city/highway/combined (or MPGe for EVs), CO2 tailpipe grams/mile, estimated annual fuel cost (USD), annual petroleum use (barrels), EPA greenhouse-gas score (1-10), 5-year savings vs the average new vehicle, plus transmission, drivetrain, cylinders, displacement, fuel type, EPA size class, and electric range for EV/PHEV. Authoritative EPA test figures — the real ratings an agent should not estimate. Keyless, public-domain (FuelEconomy.gov), covers model years 1984+.

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.

Search US federal biomedical research grants via NIH RePORTER. Filter by term (free-text over project title, terms, and abstract), org (funded institution name), pi (principal-investigator name), and/or fiscalYear; page with limit (1-50) and offset. Returns each award with project number, title, fiscal year, award amount (USD), contact PI, organization (name, city, state, country, department), funding agency/institute, and project start/end dates — newest fiscal year first, with a total match count. Data: NIH RePORTER, free and public-domain. Fresh post-training award data agents cannot know; pair with /api/research/org (ROR) and /api/research/author (ORCID). Use for funding landscape research, competitor/lab tracking, and grant-opportunity context.

Grade a domain's email-authentication and DNS-security posture from live DNS in one call: SPF, DMARC (policy + alignment), DKIM (for the supplied or common selectors), MTA-STS, TLS-RPT, DNSSEC, CAA, and BIMI. Pass domain (and optional dkimSelector). Returns an overall letter grade, a summary (spf/dmarcPolicy/dkim/mtaSts/dnssec/caa/bimi + spoofingProtected), and a per-mechanism block with the raw record, parsed tags, and specific issues (e.g. 'DMARC p=none — monitor only', 'SPF ~all soft-fail', 'no MTA-STS'). Sourced from live public DNS via DNS-over-HTTPS — an LLM cannot know a domain's current records. For deliverability/anti-spoofing audits, vendor security review, and phishing-resistance checks. DKIM is selector-based (selectors aren't enumerable), so 'not found' only means none of the checked selectors resolved.

FEMA National Risk Index for a US county — the authoritative natural-hazard risk profile. Look up by countyFips (5-digit STCOFIPS), by state + county name, or by a lat/lon point. Returns the composite Risk Index score/rating/national-percentile (an 18-hazard model combining Expected Annual Loss × Social Vulnerability ÷ Community Resilience), each component (expected annual loss in dollars, social vulnerability, community resilience) with its rating, and per-hazard risk ratings + expected-annual-loss for all 18 natural hazards (wildfire, earthquake, hurricane, riverine & coastal flooding, tornado, heat/cold wave, drought, etc.). The structural natural-hazard risk picture an LLM can't recall — for siting, insurance, and resilience planning. Free, public-domain. Complements geo.flood-zone (which is flood SFHA only).

Fetch the authoritative text of any section of the US Code of Federal Regulations by title and section number — for example title 12, section 1026.43 returns Regulation Z’s ability-to-repay standards. Returns the canonical citation, section heading, full plain text, Federal Register source credit, the as-of date, and a link to the official eCFR page. An optional date parameter (YYYY-MM-DD) retrieves the historical text in force on that date, back to 2017. Data from the Electronic Code of Federal Regulations (US GPO / Office of the Federal Register), public domain, updated daily — verify regulatory citations against the authoritative source instead of relying on model memory.

SEC Form 144 filings — notices of PROPOSED insider stock sales (intent to sell restricted/control shares), newest first, via EDGAR full-text search. Market-wide by default, or filter by ticker/company/keyword (q). Each: filer + issuer names, filing date, accession, CIKs, and a filing URL. The heads-up before a Form 4 confirms the sale. Complements finance.insider-trades.

Verify a US trademark by USPTO serial number (8 digits) or registration number. Returns the word mark, LIVE/DEAD status with the detailed status description and date, filing and registration dates, current owner (name, entity type, citizenship), mark type (trademark / service mark / certification mark), standard-character flag, abandonment date when applicable, and the international classes covered with their descriptions. Authoritative real-time USPTO data — confirm a mark exists and is active before relying on it for clearance, licensing, or due-diligence work. Lookup is by number only (no text search); siblings: /api/patents/search, /api/law/case-verify.

Resolve a US street address to its congressional district (119th Congress), state, and county, via the US Census Bureau geocoder. Returns the matched/normalized address, latitude/longitude, state (name + 2-letter abbreviation), county, and the district number within the state (null for at-large or non-voting delegate districts). The point-in-polygon district lookup is something an agent can't do from a sandbox. Pair it with the gov/congress.* endpoints to find the representatives once you have the state + district. Public domain, keyless.

Decode an EVM smart contract. Pass chain (ethereum, base, polygon, arbitrum, optimism, bsc, avalanche) + address; returns whether the contract is source-verified (Sourcify), its name/compiler/language, whether it is a proxy and its implementation address, and human-readable function and event signatures from the ABI. Optionally pass selector (a 0x 4-byte function selector) to decode what it calls — resolved from the contract's own ABI when verified, otherwise from the public 4byte directory. Pairs with crypto.tx (which gives a `to` address + calldata): turn an opaque contract + selector into "what is this and what does it do." Free, keyless.

Latest daily stock quote for a US-listed ticker. Returns the most recent completed trading session: open, high, low, close, volume, VWAP, and trade count, plus the change and percent change versus the prior session, and company reference data (name, primary exchange, security type, currency, market cap). NOTE: this plan tier serves end-of-day / delayed data (the response flags delayed=true), suitable for daily snapshots, fundamentals context, and post-close analysis rather than real-time trading. Pass ticker as a US symbol (e.g. AAPL, MSFT, BRK.B). Market data by Massive (formerly Polygon.io).

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.

DeFi total-value-locked (TVL) metrics via DefiLlama. With no params, returns the top protocols by TVL (name, slug, category, TVL, 1-day and 7-day % change, chains) plus total DeFi TVL across all chains. Pass protocol=<slug> (e.g. lido, aave, uniswap) for a single protocol's TVL, category, momentum, and chains; or chain=<name> (e.g. ethereum, solana, arbitrum) for that chain's TVL. Distinct from crypto.markets/token-price (spot prices) — this is protocol- and chain-level capital locked in DeFi, which an agent can't know from training. Free, keyless.

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.

CFTC Commitments of Traders (COT) — weekly futures positioning for a market (free/keyless). Match a market by name (e.g. 'E-MINI S&P', 'GOLD', 'CRUDE OIL', 'BITCOIN'). Each weekly report: open interest, large speculators (non-commercial) long/short/spread, commercials (hedgers) long/short, small (non-reportable) traders, and week-over-week changes. For positioning/sentiment analysis.
