I have probably about a dozen domain names (mine, not $work's) altogether. I think three are at Gandi, the remainder at Namecheap. I believe that every one of the domains that I actually use (some are old and now unused but I still want to keep them), I'm running the DNS via AWS Route 53. I don't actually use their API as my RRs pretty much never change, the service is just very reliable. That may change in the near future (I manage the authoritative nameservers for $work) but I can't recall a single issue I've had w/ Route 53 (or Gandi or Namecheap, for that matter).
