We have recently added XML API to SheerSEO. This should be useful for those of you who wish to write their own UI or for applications that want to embed SheerSEO data in their current interface.
It currently only supports showing the current SERPs and the historical SERPs search terms, but if there will be a demand we’ll add more to it.
The XML interface requires an API key that will be issued by us.
If any of you are interested in using the API please contact us.
