Which nameservers do I delegate my domain to?

Delegate your domain to dns1.int.yt and dns2.int.yt. Both names resolve to the same anycast address, so queries are answered from whichever network reaches it first.

Can I point my root domain at a hostname instead of an IP address?

Yes. Publish an ALIAS record at the apex. A CNAME is not allowed there because the apex must also carry SOA and NS records; ALIAS is.

Is the REST API available on the free plan?

Yes. Every tier gets the same API, the same record types and the same anycast infrastructure. Paid tiers only raise the domain-slot ceiling.

A CNAME cannot exist at the apex of a zone, because a zone apex must also carry SOA and NS records. ALIAS solves that: keep your SOA and NS where they belong and point the apex at any hostname, which resolves like an A record.

Rejected next to ALIAS

A
AAAA
CNAME
ALIAS (duplicate target)

Two address records at one name is ambiguous, and a CNAME there would make the zone self-referential. Both are refused at validation.

Allowed next to ALIAS

These describe something other than the address at that name, so an ALIAS alongside them is unambiguous and is accepted.

Delegate to these two

Both names resolve to the same anycast address, so a query is answered by whichever network reaches it first rather than by one far-away origin. You can confirm that yourself:
