Content vs Search CPC data?

[shorebreak]

Does anyone know if a tool or service exists that can provide Google and/or Yahoo **contextual** CPC data for large amounts of keywords (aka 1M+ keywords)?

Specifically, what I'm looking for is data on what average CPCs are - in Google & Yahoo's contextual networks - for large amounts of keywords across the top ~10 major verticals.

Thanks in advance for replies.
