Kickbox
Kickbox's open, keyless disposable-domain lookup
Kickbox exposes a free open endpoint that answers a single yes/no question: is this address on a known disposable/temporary email domain? Pass any email and get back a tiny JSON boolean. It is a subset of Kickbox's paid verification suite, but this check needs no account.
