sthan.io
A set of REST APIs for US addresses and IP location, made for developers. Verify a US address (corrected address, ZIP+4, county and a deliverability status), parse one line of freeform text into house number, street, unit, city, state and ZIP, autocomplete addresses as a user types, geocode addresses to latitude/longitude and back, and look up the location and network (ASN, ISP, mobile/proxy/hosting flags) of any IPv4 or IPv6 address. India PIN code, city and locality autocomplete too. Inputs can be messy: typos, abbreviations and parts out of order are fine. Every product has a free monthly tier, no credit card is needed to start, address verification starts at $12 a month for 10,000 requests (other products have their own plans), and every price is listed on the site. Annual billing costs less than monthly on every plan. Docs, OpenAPI spec, Postman collection, an MCP server and a CLI are in the documentation.
