AdWordsAPI Advisor posted in a Google Groups thread that Google is now able to drop the prices they charge for using the AdWords API. How can they do this now? Debbie Leight, Product Marketing at Google, said because Google was able to enhance the API system to “drive greater efficiencies.” Those new efficiencies are now represented in a new lower rate.

Here is the revised rate chart:

Service Name, Former Rate (in API units), New Rate
* addAds: 125 -> 50 per item
* addCriteria: 25 -> 20 per item
* updateCriteria: 10 -> 3 per item
* getKeywordVariations: 25 -> 20
* getKeywordsFromSite: 25 -> 20
* estimateAdGroupList: 25 -> 20 per item
* estimateCampaignList: 25 -> 20 per item
* estimateKeywordList: 25 -> 20 per item
* scheduleReportJob: 1000 -> 500
