Anthropic Ends Third-Party Tool Support for Claude Subscriptions to Manage Capacity

Claude

Apr 5, 2026 · Updated Apr 25, 2026

Starting April 4, 2026, Claude subscriptions will no longer cover usage on third-party tools like OpenClaw. This shift moves high-intensity external usage toward API-based billing or discounted bundles to protect compute capacity for direct users.

Anthropic is updating its Claude subscription terms to exclude usage through third-party tools like OpenClaw. Starting April 4, 2026, at 12pm PT, these platforms can no longer draw from standard monthly message limits. Instead, users must connect via a Claude API key or purchase new, discounted usage bundles.

This change addresses the strain that automated third-party agents place on compute resources. Standard subscriptions were built for human-speed chat, not the high-volume usage patterns typical of external tools. By decoupling these services, the company is prioritizing capacity for its own direct products and API customers.

If you use external tools to access Claude, you can transition to pay-as-you-go API billing or buy discounted usage bundles. Current subscribers will receive a one-time credit equal to their monthly plan cost. If the new policy doesn't fit your workflow, you can request a full refund via email.

OpenAI Enables ChatGPT Subscription Portability for OpenClaw Agent Workflows

OpenAI enabled ChatGPT account sign-in for OpenClaw, the multi-channel AI agent runtime, letting existing subscribers power autonomous agents with their paid plans. This move lowers the cost of running autonomous agents by bypassing usage-based API billing for Plus and Pro subscribers. It positions OpenAI as a more economical platform for developers compared to competitors restricting third-party subscription use.
