CVE change feed — the CVE records MODIFIED within a time window, so an agent can incrementally maintain a vulnerability view instead of re-scanning. Pass since (YYYY-MM-DD or ISO datetime); until defaults to now (window must be ≤ 120 days, the NVD limit). Optionally narrow by keyword (product/text) or cpe (exact CPE). Returns each changed CVE with its id, published + lastModified timestamps, current vulnStatus (e.g. Modified, Analyzed, Rejected), best-available CVSS score/severity, description, and kevListed — whether it is now on the CISA Known-Exploited Vulnerabilities catalog (the high-signal flag for a poller). Newest modification first. Sourced live from NVD (NIST) + CISA KEV, free/keyless. Pair with security.cve for full per-CVE detail.

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 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.

Retail electricity price and sales for a US state by customer sector (residential, commercial, industrial, transportation, all), monthly, newest first, from EIA. Returns average price (cents/kWh), sales (MWh), revenue ($M), and customer count per month. Public-domain, live-wrap. More granular than energy.prices (which is the national all-sector benchmark only).

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.

Ground-truth soil profile for any US latitude/longitude from the USDA-NRCS SSURGO survey (Soil Data Access). Returns the soil map unit plus its component soil types ranked by composition percent, each with taxonomic order/class, drainage class, hydrologic group, and representative slope. Keyless, public-domain. Use for agronomy, land assessment, hydrology, septic/foundation suitability, and crop-fit reasoning. Coordinates over water or outside surveyed areas return an empty component list.

US Drought Monitor severity for a county (5-digit FIPS) or state (2-letter code). Returns the weekly percent of area in each drought category — None, D0 (Abnormally Dry), D1 (Moderate), D2 (Severe), D3 (Extreme), D4 (Exceptional) — newest week first, plus the worst category present each week. Keyless, public-domain (NDMC/USDA/NOAA). This is the official metric behind USDA disaster-program eligibility; use for crop-risk, water, and insurance reasoning.

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).

Electricity generation mix by fuel type for a US state (2-letter) or "US", from EIA — the most recent monthly net generation (thousand MWh) broken out by fuel (natural gas, coal, nuclear, solar, wind, hydro, etc.) with each fuel's percent share and the all-fuels total. Public-domain, live-wrap. Use for grid carbon-intensity, decarbonization, and energy-policy reasoning. (For benchmark energy prices use energy.prices; for retail electricity rates by state/sector use energy.electricity-rates.)

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.)

UK Food Standards Agency food hygiene ratings (FHRS) for an establishment. Search by business name and/or postcode and get matching establishments with their hygiene rating (0-5 in England/Wales/NI; Pass / Improvement Required in Scotland), rating date, the three component scores (hygiene, structural, confidence in management — lower is better), business type, local authority, full address + postcode, and geocode. Free, Open Government Licence (commercial use permitted). Authoritative inspection data an LLM cannot recall — for food, hospitality, and consumer-safety agents.

Active in-flight weather hazard advisories (SIGMETs and AIRMETs) from the NOAA Aviation Weather Center. Returns current advisories over a lookback window (1-24h), optionally filtered by hazard (CONVECTIVE, TURB turbulence, ICE icing, IFR, MTN OBSCN mountain obscuration, ASH volcanic ash). Each advisory carries the issuing office, type (SIGMET/AIRMET/OUTLOOK), hazard, severity, valid-from/to times, affected altitude band (feet MSL), movement (direction/speed), and the raw text bulletin. Keyless, public-domain (NOAA). The active-hazard layer aviation agents need — distinct from aviation.metar (station conditions) and aviation.taf (forecasts). Not for navigation.

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.

US federal campaign finance from the FEC (openFEC). Two modes: pass name to search candidates (returns FEC candidate id, party, office, state, district, incumbent/challenger, status, and election cycles); or pass candidateId (e.g. P80000722) to get that candidate's aggregate financial totals — total receipts, disbursements, cash on hand, and individual / PAC / party / self contributions in USD for the newest cycle, alongside identity. Free, public-domain (FEC). Search by name first, then pass a returned candidateId back in for the money. For donor/spend diligence, political research, and disclosure lookups.
