Claude Plans Add Monthly API Credits Starting June 15
Good news: starting June 15, Claude subscribers will receive a separate monthly API credit – $20, $100, or $200 depending on the plan.
These funds can be used to work with Agent SDK, run Claude in interactive mode via claude -p, GitHub Actions, and third-party apps based on Claude. At the same time, regular chats and Claude Code use separate limits and do not affect the API balance
