I've recently subscribed too. The huge context window is a game-changer and I can't wait for API access. Unfortunately it hallucinates a lot. It's amazing for extracting information out of large documents, altough doing so made me realize how limited current models are in terms of detecting "subtleties" that would be obvious to a human.
I have API access using AWS Bedrock which is hosted claude v2. boto3 has a client to trigger the completions but I've been practicing using just the playground in AWS console.
