So, September was apparently only a month long – sounds fake, but OK – and we’re ready to give you the monthly financial API ratings.
We’ve now split out financial API ratings and the non-financial API ratings into separate weekly and monthly reports. This allows us to give you a more focused view on the different classes of APIs you care about.
In particular, we have been seeing increased adoption of and interest in APIs in the financial sector as uptake of Open Banking accelerates and APImetrics has over the last few weeks been able to add a many UK Open Banking APIs to the ones we monitor and the performance of which can be seen at our API.expert (http://api.expert) site.
Now, onto what the past week tells us about the state of the world of financial API ratings as we move further into October 2020.
API Performance Headlines
To compile our financial API ratings, we look at more than 200 APIs. Then we pull all the metrics together to give you a general feeling for financial API quality in a particular category.
We do see that certain providers consistently vie for top spot in their financial API ratings category. Read on to learn more!

Something of interest
APImetrics has recently begun monitoring a number of APIs in the Open Banking – UK – Production category. We are planning to add more in the near future. What’s good about these APIs is that they allow us to compare directly the performance of different banks with APIs that perform the same tasks.
