https://platform.claude.com/docs/en/agent-sdk/overview#get-s... reads to me like you have to use the public API for the Claude Agent SDK, not a Claude Code plan:

> Unless previously approved, we do not allow third party developers to offer Claude.ai login or rate limits for their products, including agents built on the Claude Agent SDK. Please use the API key authentication methods described in this document instead.
