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.
It can be as simple as placing the wallet.dat file holding the addresses in the data folder.
You can also use the file->import wallet command and browse to the wallet.
Finally, if the debug file shows some missed keys on importing that way you can try with the -salvagewallet flag.
