Anthropic Allows Third-Party Agents to Reconnect with Claude Subscription, But Adds Independent Usage Limits

Odaily reported that Anthropic announced a new Agent SDK billing policy effective June 15, 2026. Under the new rules, third-party agent tools like OpenClaw will be allowed to reconnect with the Claude subscription version, but will require a separate "dedicated monthly allowance" that is no longer shared with regular chat quotas.

Previously, in April of this year, Anthropic restricted third-party tools from using Claude subscription quotas citing abuse prevention. This adjustment is seen as the final resolution to the related controversy—reopening third-party access while completely isolating agent calls from regular chat quotas.

Specifically, Pro users will receive a $20 dedicated monthly allowance; Max 5x and advanced Team plans get $100; Max 20x and advanced Enterprise plans receive a maximum of $200. These allowances can only be used for third-party applications, self-built agent projects, and claude-p backend command calls. The allowance resets monthly, and any excess usage will be charged at standard API rates.
