Determining NPC/Player from CharacterID

Problem:
I have a character ID, and I need to determine whether it is an NPC or a player character. I cannot do this via the CharacterInfo API because it returns a "bad request", and I do not desire being blacklisted.

Someone mentioned in a different post that it may be possible using the SDE, but I have explored that and only see Agent NPCs in it.

Can anyone think of a good way to do this?

Thanks!

Easiest way is definitely calling CharacterInfo.

CCP Prism X also recently added typeID's to a lot of API calls recently, more information here.

If you must insist on doing it the hard way, then the most helpful tip I can give you is this: All ID's used to be in certain ranges.
I don't have the exact ranges ready right now, but it's something like this:

1000000 - 1100000 = NPC corps
90000000 - 9xxxxxxx = characters
98000000 - 9xxxxxxx = corps

This stopped being true a while ago though, so it will not work out most of the time.
You should really be using Prism's new stuffs.

The typeIDs are great, except they're not on every API. For example, if all I have is a characterID, and I want to find the CEO of his corporation. The normal progression for this would be:
- call CharacterInfo to get CorpID
- call CorporationSheet to get CeoID
- call CharacterInfo to get Ceo's info

And the problem is when the original character is in an NPC corp, meaning his CEO is an NPC. I can't rely on using the SDE because only agent NPCs are in there.

For a large application, would calling CharacterInfo with NPC ids (getting a "bad request" response) regularly lead to blacklisting?

Not unless you do it 500 times a minute...
Generally, unless you literally have 10 threads going 24/7, you're good.

As for NPC corps, those are still in the ranges listed above. (Or heck, you could even compile a list quickly by simply copying them from Eve.)
