Yes, they sent an email about it. You can also use the Claude SDK with an OAuth token ("claude setup-token" output) and it counts against the regular limit. Maybe they were afraid of losing users dependent on ACP (Zed editor and other compatible tools), since Claude Code does not have native ACP support and integrates only through the SDK?

I can't find the page now but yes they quietly "paused" the June 15th rollout of API pricing for -p headless. Presumably to come back again one day.

I think they didn't even bother making a separate post about their backpedaling, they just slapped some disclaimers onto the existing page:

Update June 15: We're pausing the changes to Claude Agent SDK usage described below. For now, nothing has changed: Claude Agent SDK, claude -p, and third-party app usage still draw from your subscription's usage limits. The previously announced monthly credit, which would have been available to eligible claimants in connection with these changes, isn't available. We’re working to update the plan to better support how users build with Claude subscriptions. When we have an update, we'll share it before anything takes effect.
