Since this article was written, we've (Stadia Maps) also launched and made significant progress with our own Geocoding API: https://stadiamaps.com/products/geocoding-search/

It was originally based on Pelias, but we've since augmented with additional data sources (such as Foursquare OS Places) and significantly improved the baseline for performance and accuracy.

Happy to answer questions on the topic!
