Search the UK Companies House register by name or keyword and return matching companies with company number, register status and a derived is_active, type, incorporation and cessation dates and the register's one-line address snippet. Use this first when you only have a name, then call the per-company capabilities with the returned company_number. Ordering is the register's own, echoed as match_rank — a position, not a relevance score. Use when: Look up a UK company by name.

Turn a company-name fragment or stock ticker into the SEC EDGAR identifiers. Searches the SEC listed-security index and returns ranked matches with the 10-digit CIK, ticker, registered name and listing exchange. Deterministic ranking: ticker exact, then name exact, then name prefix, then name contains. Use it for names — the other company.us.* capabilities take a ticker directly. Use when: Which SEC filer and CIK does the company name "Apple" belong to?

Find Legal Entity Identifiers by company name in the global GLEIF register, optionally narrowed to one country. Returns the LEI, legal name, registration and entity status, jurisdiction, legal address and the local registry the entity is registered at — the identifier bridge between national company registers worldwide. Use when: What is the LEI for this company?

European Central Bank euro foreign exchange reference rate for a pair - the official daily fix used for accounting, invoicing and reporting - latest or any date in the last 90 days. The ECB publishes EUR/XXX only, so inverse and cross rates are computed from the same fix and named in rate_derivation. One fix per TARGET working day, not a tradable market rate. Use when: Convert or report an amount at an official daily rate both sides of a contract can verify against the ECB.

Convert a one-line US street address into coordinates using the US Census Bureau Geocoder. Returns the standardised matched address, latitude and longitude to 6 decimal places, the TIGER/Line segment and parsed address components. Coordinates are interpolated along street address ranges, not rooftop or parcel positions. No match is a normal answer, not an error. Use when: Convert this US street address to latitude and longitude.

Return the US Census Bureau geographies containing a latitude/longitude — state, county, census tract, block group, census block, incorporated place, congressional district and ZIP Code Tabulation Area — each with its FIPS or GEOID. The standard way to attach official US statistical geography to a point. Use when: Which county and census tract is this coordinate in?

Identify which carrier issued a tracking number using a deterministic, versioned signature set - prefixes, lengths, carrier check digits and UPU S10 structure - returning the carrier, how distinctive the match is, every ranked candidate with typed evidence, and the parsed S10 details. No upstream call and no carrier account required. Use when: Which carrier is this tracking number from?

Active National Weather Service watches, warnings and advisories for a US coordinate or a two-letter state or marine area code - event, severity, certainty, urgency, headline, affected areas and zone codes, and effective/onset/expiry times in UTC. Read at request time, so an empty list means nothing is active. The 5 newest come back by default; detail=full adds the NWS narrative. Use when: Decide whether an active US weather warning affects a location before dispatching or travelling.

Latest surface observation from the nearest National Weather Service station to a US coordinate, with the station identity, the observation time (observed_at), its age in seconds and an is_stale flag. Station observations are reported roughly every 20-60 minutes, so this is the most recent measurement, not a real-time reading. Readings that fail the station's quality control are returned as null. Use when: What was the most recently observed temperature at these US coordinates?
