Ask HN: Domain registrar with API and no shady fees?

[cuchoperl]

I want to offer domain name registration for mini-sites inside my app.

Is there any registrar where I can programmatically register domains and assign DNS parameters on behalf of other people?

Hopefully this registrar will not have shady fees like $250 "restore fees" (eNom) or $120 "redemption fees" (name.com).
