Geocode the address '1600 Pennsylvania Ave NW, Washington, DC 20500' using the Public_AR_Current benchmark.

I've geocoded the address. The coordinates are Longitude: -77.03636, Latitude: 38.89715. This was matched using the Public_AR_Current benchmark.

What census tract and block are located at coordinates -76.9274, 38.8459?

Checking census geographies... Those coordinates correspond to Census Tract 8007, Block 1004 in Prince George's County, Maryland (using the Current vintage).

List all available geocoding benchmarks.

I've retrieved the available benchmarks. You can use 'Public_AR_Current' (ID: 4), 'Public_AR_Census2020' (ID: 2020), or 'Public_AR_Census2010' (ID: 10) for your queries.

Yes! Use the `geocode_oneline` tool with `returntype` set to 'geographies'. Provide the address and a benchmark (like 'Public_AR_Current') to receive full geographic metadata.
