US geocoding you can keep the results from: forward and reverse geocoding, batch of up to 10,000, honest accuracy types (rooftop, range interpolation, street, place, ZIP), and appends from public data: Census tract and block group, congressional and state legislative districts, school districts, time zone. Built on the National Address Database and TIGER/Line, so results may be stored forever on every plan. One key, JSON only, with an MCP server for agents. Operated by APIDirectory.
