I've been messing about writing a script which will catch ccTLD domains (mainly .io tlds). I've started by using an api which sends lots of requests to purchase a domain just before it expires but not had any luck so far. Do I just need more registrars and send lots of requests to these in parallel or are there other options. I'm not competing with the likes of Namejet or Pool as they don't catch .io domains. There are some smaller sites that do this so don't believe they have anything special I wouldn't be able todo.
