free API vs Enom,Dynadot,Pool and others API
Anyone try free API and have any success to catch dropped domains?
I think to try Enom API (200$ year)for my domain software but want your suggestion opinions what you think.
Or first implement free API and test?
As i know ENOM support all tlds for check while dynadot have some limits for net and com or i'm wrong

I've heard that Enom is not letting Api users submit registration attempts during drop period hours. So it would be worthless. Contact them first.
