There’s no reason you can’t do both... simply build your internal code to check against multiple sources. You can asynchronously hit your bloom filter, HIBP, DeHashed, etc. and cut short whenever there is a hit. In this way you get the best of all worlds; speed, highest degree of accuracy, and reduced dependency on a single external API.
