Anthropic disables Claude Code OAuth tokens for OpenClaw, requiring separate billing

Anthropic's policy change for third-party Claude usage

Anthropic is implementing a significant change to how Claude subscriptions can be used with third-party tools. Starting April 4 at 12pm PT / 8pm BST, users will no longer be able to use their Claude subscription limits for third-party harnesses including OpenClaw.

The change specifically affects the ability to use Claude Code CLI tokens or long-lived OAuth tokens with OpenClaw. According to an email sent to users, these tokens will require "extra usage" billed separately from subscriptions through a pay-as-you-go option.

Technical details and enforcement

The source indicates that OpenClaw already sends Claude Code signatures for these tokens. The enforcement mechanism isn't specified, but possibilities mentioned include updating signatures or implementing more complex token refresh systems. One contributor familiar with the codebase suggests they'll attempt to work around the restriction and submit a PR fix if their tokens stop working.

Transition details and alternatives

Anthropic is offering a one-time credit for extra usage equal to the user's monthly subscription price, redeemable by April 17. They're also introducing discounts of up to 30% for pre-purchasing bundles of extra usage.

Users who prefer not to enable extra billing have the option to request a refund of their subscription. The policy applies initially to OpenClaw but will be rolled out to all third-party harnesses shortly.

According to Anthropic's email, the change is due to these tools putting "an outsized strain on our systems" and the need to prioritize customers using core products like Claude Code and Claude Cowork.
