Thank you for your interest! I am hoping to start looking into it in the next few days, if all goes well, a full SERP API is likely to be available in a month or two. I’ll drop an update here when it’s ready.

Interested ! When do you think features will be available ? thanks

This is a fast and simple version of a SERP API - I have a full SERP (or close to it) API on my roadmap which is going to support the parameters you mentioned.

Stay tuned and thanks for the feedback!
