We are now almost halfway through October and that time of the week has already arrived again for us to look at some key API ratings over the past seven days.
We recently launched API.expert as a simple way to provide everybody with insights into the API economay and the leading API ratings in different categories in particular.
The basic service is free and will remain free. But other, related API ratings services will be built on top of it, including your very own API.expert dashboards if you want them!
We are expanding our coverage of Open Finance APIs from around the world, so one of the major changes we made recently to these round ups has been to pull out the financial APIs. Look out for the separate report on financial APIs.
Each week, month, and year we’ll look at API ratings in a variety of sectors for their quality CASC score using our patented system (US Patent 10,644,962, if you fancy a little light bedtime reading) that allows you to see the API ratings and compare them to other ones, as well as factors like uptime and availability.
If something is missing in our API ratings that you think should be here, don’t hesitate to drop us a line!
Now, onto what the past week tells us about the state of API ratings during this insane week of an unending year.
API Performance Headlines
To compile our API ratings, we look at more than 200 APIs. Then we pull all the metrics together to give you a general feeling for API quality in a particular category.
We do see that certain providers consistently vie for top spot in their API ratings category, including GitHub and Google. Others do less well, such as Halifax and the NHS.
