Anthropic's Claude Code API access differs from subscriptions

Anthropic's Claude Code API has distinct access and billing pathways that can cause confusion for developers. Unlike a simple subscription, using Claude Code may require specific credentials such as an ANTHROPIC_API_KEY or cloud provider tokens, which take precedence over a standard Claude Pro or Teams subscription. This prioritization can lead to unexpected billing or authorization errors if older API keys are present in the environment, even when a subscription is active. AI
