Enhanced Address Finder
Enhanced Address Finder is an API that retrieves, verifies, and auto-completes UK addresses in real time. It integrates into web forms and shopping carts to reduce input errors and ensure accurate, standardised address data. It also provides property valuation insights linked to each address.
The code inserted at your end has a few lines of code. When users enter a post code into your form, you catch this and send it to us and we send back a list of addresses for that post code, or inform you if the post code is not valid.
Additionally, you may also send us an exact address and we can send back the property valuation, and other property details such as council tax band, number of bedrooms, etc.

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.
