## Spaw

Verification API that bills per answered lookup across six signals on one key and one balance: Email verification, Phone intelligence, IP intelligence, Address verification, Business verification against open registers, and Cross-signal consistency, which runs any subset of the first four in one call and names where they agree and where they do not. The address side reads a written address against its own country's format, names the kind of delivery point behind it, checks the postcode against the national directory and follows the building into that country's own address register where one is installed.

## Geoapify

Geoapify is a location platform (maps, routing, places and geocoding) whose Geocoding API is also sold for address validation: an address is matched against open datasets such as OpenStreetMap and OpenAddresses and returned with coordinates and confidence scores for the city, the street and the building.
