Anthropic allows third-party agents to reconnect to the Claude subscription version, but with new independent quota limits

Anthropic announced that starting from June 15, 2026, a new billing policy for the Agent SDK will be implemented. According to the new regulations, third-party Agent tools such as OpenClaw will be allowed to access the Claude subscription version again, but they must use a separate "exclusive monthly quota," which will no longer be shared with the regular chat quota.

Previously, Anthropic had restricted third-party tools from accessing the Claude subscription quota in April of this year to prevent abuse. This adjustment is seen as the final solution to the related controversy, which is to reopen third-party access while completely isolating Agent calls from the regular chat quota.

Specifically, Pro users will receive a monthly exclusive quota of $20; Max 5x and advanced Team versions will receive $100; Max 20x and advanced Enterprise versions can receive up to $200. The relevant quotas can only be used for third-party applications, self-built Agent projects, and claude-p backend command calls, with quotas refreshing monthly, and any excess must be paid at the standard API rate.
