Tools as reported by the server

• suggest_places
  Search for a place by partial name, misspelled name, or partial code — the resolver that turns what a person typed into something the other tools can look up. Fuzzy matching is built in: "beverley hills" finds Beverly Hills, "san fransisco" finds San Francisco, and a partial code like "902" finds th
• zip_lookup
  The full record for a postal code — the main location-intelligence tool. Takes a US ZIP Code, a US ZIP+4, a Canadian FSA, a Canadian postal code, or a latitude,longitude pair, and returns the city, state or province, county, whether it spans more than one county, area codes, elevation, metro area an
• zip_facts
  Statistics about US ZIP Codes and Canadian postal codes: how many exist, how they break down by type, delivery point and carrier route totals, per-state tables, and ranked lists such as the ZIP Codes with the most carrier routes. Every figure is generated from a stored query against the source data,
• quick_zip
  The fast, small answer for a postal code. Takes a US ZIP Code, a US ZIP+4, a Canadian FSA, a Canadian postal code, or a latitude,longitude pair, and returns the code's city, state or province, county, and whether it spans more than one county. Given a ZIP+4 it also returns the street ranges making u
• city_name_rules
  How USPS names a ZIP Code, and which of those names may be used on mail. Each ZIP Code has exactly one preferred city name plus alternates, and some alternates are NOT valid for addressing — for 08088 NJ, SHAMONG is valid while SHAMONG TOWNSHIP is not. Returns the rules, the counts and a worked exam
• radius_search
  Find every US ZIP Code and Canadian postal area within a radius of a centre point, with the distance to each. The centre takes a US ZIP Code, a US ZIP+4, a Canadian FSA, a Canadian postal code, or a latitude,longitude pair; a ZIP+4 searches from its parent ZIP, and coordinates are used as the point
• about_data
  Where this server's data comes from: for each dataset the authority behind it, the edition served where the source publishes editions (TIGER/Line, ACS, ZCTA), how often a new release is taken, and a ready-made citation string. Costs nothing and needs no key.
• distance
  Distance between two places, in miles and kilometres, plus the compass bearing from the first to the second. Each end takes a US ZIP Code, a US ZIP+4, a Canadian FSA, a Canadian postal code, or a latitude,longitude pair, and the two ends can be different kinds — a US ZIP to a Canadian postal code wo
• validate_address
  Validate and standardise a US street address and return its ZIP+4. US ONLY — unlike the postal-code tools, this does not cover Canada. Send the address on one line in mailing order: number and street, then any unit (APT 4, STE 900, #9), then city, state and ZIP. It tolerates ordinary slips (a misspe
• county_reference
  US counties and county equivalents — all 3,235 of them — with their Census and USPS names, which disagree for over a hundred, plus ANSI code, legal type, land and water area, and USPS delivery footprint. Filter by state to get every county in that state: without a filter only the first 25 are return
• metro_area_reference
  US metropolitan and micropolitan statistical areas (CBSAs) — all 935. Of those only 393 are metropolitan; the rest are micropolitan and are NOT metro areas, so do not treat a CBSA count as a metro count. Each carries its divisions, parent combined area, land area and delivery footprint, plus the CMS
