This issue is to track the remaining non-real values for the api/ folder. The goal of this issue is to obtain 100% real values for all of the features in api/.

Milestones Reached:

• At the end of 2020, we had reached a total of 91.16% real values, surpassing the 90% goal set for the quarter! 🎉
• Halfway through 2021, we reached the 95% mark, leaving only 5% left to go! 🎉
• At the end of September 2021, we have reached 98% real values, leaving only 2% remaining! 🎉
• At the start of November 2021, we have reached 99% real values! 🎉
• At the start of December 2021, we have reached 100% for all main eight browsers! 🎉

Below are alphabetically-sorted categories of APIs. Note that some data points may also be completed already, if so, let us know and we'll mark is as completed. (List generated via https://github.com/queengooborg/bcd-toolkit/blob/main/get_nonreal.py). We're done! No more left to go!
