A Claude subscription does not cover third-party tools: an API key is required
As of 22 September 2026, a Claude subscription does not cover third-party tools: Anthropic directs them to an API key. Pro and Max work with the official Claude Code and supported IDEs. Anthropic may enable such tools for some paid subscribers through usage credits, but charges them separately from the subscription limit.

Periodic sad reminder: an Anthropic subscription still does not cover third-party tooling :(

On 9 January, Anthropic added protections against apps that impersonated Claude Code. On 3 April, developer Edd Mann reported that Pi, Jeeves, and My Own Coding Agent lost access to Max and Pro after the block.
Official Claude Code on macOS, Linux, and WSL is installed with `curl -fsSL https://claude.ai/install.sh | bash`, and the `claude` command opens authorization.
The path for an external agent. In Claude Console, open Settings, then API keys and Create key. Pass the key as `ANTHROPIC_API_KEY`: SDKs will pick up the variable automatically. According to the 22 September pricing, Sonnet 5 costs $2 per 1 million input tokens and $10 per 1 million output tokens.
Anthropic retains two tracks: a subscription for its own applications and an API for external coding agents.
