I've built an ad network that supports exactly this: I give you (the publisher) a bag of JSON or XML that tags up the content, and you decide how to render it. I typically pay on click, but I have paid impressions in some cases where the publisher and I can reach a level of trust. I don't think wakatime.com would be an appropriate publisher for me, but maybe you have other sites that are more appropriate.

My original goal was avoiding ad blockers: By having the publisher render the ad themselves, it doesn't look obviously an ad, and as long as the publisher doesn't make the page itself an ad farm, users do not tend to block with custom CSS (that might end up in popular blocking tools). It seems to work okay- we've been operational for over five years at this point, and I've not seen one of the publisher domains or CSS show up in ublock.
