How to get Anthropic API Key when "subscribing" to Pro via iOS?
The Claude Pro subscription does not include API access; it's a subscription for Claude Chat on the web or via the app of your choice. The API is charged based on usage, and you must "pre-load" funds for that usage to be charged against. You have to create a separate API account to use it, but you *can* use the same email for that account as you do for Claude Pro. The product that includes both (not exactly 1:1 comparison, but similar) is Claude Max. You may want to consider a Max subscription if you need access to both, I've seen a lot of API users saying it saves them a lot of money. A word of advice: If you don't *have* to, don't subscribe through iOS. You're paying an extra premium to Apple for literally no reason. If you subscribe directly through anthropic.com , the price is a bit lower. More on reddit.com
