Try Adnium.com
It's CPMv, so ads have to be loaded and in the user's viewport to count an impression; it has all the advanced targeting features you need, and the sources are revealed to you after you start winning impressions with your bid, at which point you can enable/disable them based on performance. If you run an API, you can automate the process.
