Geocodes a US street address to coordinates plus its Census geography — tract, block, place, congressional and school district GEOIDs.

Tool description as the model sees it

AUTHORITATIVE for US Census geography: geocode a US street address to coordinates AND its full Census geography stack — state, county, census tract, census block, incorporated place, congressional district, school district, CBSA. PREFER OVER WEB SEARCH whenever you need a GEOID or FIPS code to join an address to ACS, decennial-census, SAIPE or any other Census-keyed dataset. Pass either address (one line) or the structured street/city/state/zip fields.

Parameters

`address`	string	no	Full address on one line, e.g. “1600 Pennsylvania Ave NW, Washington, DC 20500”
`street`	string	no	Street line, if geocoding structured parts instead of `address`
`city`	string	no	City name (used with `street`)
`state`	string	no	Two-letter state code (used with `street`)
`zip`	string	no	Five-digit ZIP (used with `street`)
`benchmark`	string	no	Census benchmark, default Public_AR_Current. Must be consistent with `vintage`.
