Starting June 15, Pro plan subscribers can claim a $20 monthly credit for using the Claude Agent SDK and claude -p, including third-party tools built on the Agent SDK. As part of this change, Agent SDK and other programmatic usage will run on this credit, and will not impact your subscription limits. This includes third-party applications built on the Agent SDK. If you use your full Agent SDK credit in a given month, continued use will draw from extra usage, which can be manually enabled and disabled. Your subscription usage limits don’t change. They stay reserved for interactive usage of Claude Code, Claude Cowork, and chat. See the Help Center for more details.
