The carrier info is all at 1,000 or 10,000 number granularity depending on
the allocation size.  The reason LNP isn't there is that I don't know of a
way to do it without a per-query fee.

Someone else pointed out tnID, which seems to be doing free LNP dips.  I'm
not sure how they're making enough money from paid reverse lookups to cover
the query fee, especially with the restrictions on caching that most (all?)
LNP providers have.  But it's great if the economics work and it's
sustainable.

Anyone with SS7 access want to allow digits to perform and cache free LNP
dips?  Happy to expose that for free too, with a client rate-limit and your
name on the result page as having sponsored it.  Assuming there's no
restriction on caching, the cached data could be reused for months.  Since
this isn't meant to be used for routing, being 3-6 months behind would be
fine.
