COORDINATES_TO_US_GEOGRAPHIES @ 1.0.0

US geographies for a point (state, county, tract; FIPS)

The US state, county, census tract, block group and 2020 census block containing a US latitude/longitude, with FIPS codes, GEOIDs and names. This product uses the Census Bureau Data API but is not endorsed or certified by the Census Bureau. Completion budget: 20 s p95, 180 s at most from payment to the record, plus the chain's settlement time; while the Census Geocoder is unavailable Arbiter refuses the quote instead of taking payment. Read from the US Census Bureau Geocoder (vintage Current_Current) after payment and cited to Arbiter's archived copy; a point on a boundary also lists the other side. Example request: {"latitude":38.8451,"longitude":-76.9283}.
