Address or place to coordinates (US Census with FIPS, OpenStreetMap worldwide) (pay per call in USDC via x402, no key)

geocoder-style result: { ok, provider, address, lat, lng, latlng, housenumber, street, city, state, postal, country, county, fips { state, county, tract, block } }. US addresses go to the US Census Geocoder (public domain); others, or country=xx, to OpenStreetMap Nominatim (ODbL, attribution included).

Pay per call with x402: $0.002 per call in USDC on Base. No key, no account: an unpaid call returns 402 with the payment requirements; retry with the X-PAYMENT (x402 v1) or PAYMENT-SIGNATURE (v2) header.
