We have somehow managed to find ourselves already well into 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!
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.

Something of interest
I remember when I first came across search engines like Alta Vista back in the Before Times of the 1990s. It seemed miracle they could work at all! And they are a technological marvel. It is perhaps not so surprising that they are slow given what they do.
