Is there an API that I could use to check a few hundred thousand bitcoin and dogecoin addresses to see if any have CLAMS that can be claimed?
Thanks.
you should download and sync the CLAM wallet, make sure your addresses are empty and there is a process to check all the addresses, it should be here in the thread, someone will answer with more specifical info or you could ask for help on the clam IRC #clams on freenode.
Eitherway you should start downloading the wallet and sync it as first step.
