TL;DR
https://api2.claudestore.store/v1, and you're coding with Claude in minutes.Why Skip the Anthropic Account?
Setting up Claude through Anthropic directly involves several steps: creating an account, waiting for API access approval (which may be denied in some regions), adding a payment method via Stripe, and navigating usage limits. For many developers, this process is a barrier.
ClaudeStore provides the same Claude models without any of those steps — instant signup, immediate key generation, and global availability.
