Preview pool domains
Returns exactly N assignable domain names, or 409 with none. Provider
health is informational, so an otherwise-ready domain can be returned
even when GET /pool reports deliverability_burned. Source-order,
warmup, billing, mailbox identity, and forwarding gates still apply.
A preview does not reserve the domains. Needs a full-access key.
POST
Preview pool domains
Authorizations
Partner API key (pk_live_… or pk_test_…).
Body

Response
