I want to use an postcode checker. Here I will put post an postcode in textbox. then it automatically filter all UK addresses related to that postcode. From where will I get this api? Is it payable or free? And also provide how to use this api. Please give me the details information of this api. I am working in php.
May I need to buy this api? From where will I buy this api? Please help me ...
Thanks, Ripa Saha
