> They recently changed the pricing around address verification as well

And this same version of the API (the latest incarnation) is also very picky about addresses, to the point where many more addresses must be "verified" before it will let a label be generated. Sure, you can just set 'ignoreBadAddess' to TRUE, but then you're just kicking the can down the road. They knew exactly what they were doing when they released this new service with free address validation, and then did the rug pull. Fucking drug dealing dark patterns there.
