HSBC in Open Banking – UK – Open Data takes the overall financial API ratings title with a median latency of 86 ms, down from 84 ms last week. An important caveat: medians can be misleading! An API might have a fast median latency but produce many slow outliers. These won’t affect the median, but they mean that users can experience many calls that were unacceptably slow. So just being fast isn’t everything. You have to be reliable too if you want to have good APIs and get a high CASC score!

Something of interest

Railsbank has the fastest median latency in Open Banking – PSD2. Financial API Ratings It has the second lowest CASC score because of having the worst pass rate and the second worst number of outliers. Some improvements are clearly called for, but it is a still a fast API. Financial API Ratings As we would expect for a fast API, the DNS Lookup Time is good. In 10 out of 22 cloud regions, it is 4 ms (plus one at 5 ms), which is pretty much as good as it can be. An excellent effort by Railsbank. They might not have many users calling them from Azure Oceania, but that’s the kind of anomaly that using an active API monitoring system can flag up. It might not be perceived as mission-critical, but it’s the kind of issue that should be identified and ironed out. Imagine if that were Azure Europe. See you again in a week as we look at the State of the financial APIs as we move into the second half of October. Also look out for our monthly report for October and, of course, our weekly and monthly reports on non-financial APIs.
