Anthropic Kills Third-Party Subscription Access — OpenClaw Is Out
As of April 4, Claude Pro/Max subscribers can no longer use OpenClaw or similar tools via OAuth. API keys still work.
Anthropic has officially cut off OAuth-based access for third-party AI harnesses like OpenClaw, NanoClaw, and others — effective today, April 4. Claude Free, Pro, and Max subscribers can no longer route workloads through these tools using their subscription tokens.
The move targets a well-known arbitrage: a $200/month Claude Max subscription was being used to run heavy agentic workflows through third-party wrappers that bypassed Anthropic's rate limits — making those plans economically unsustainable. OAuth is now restricted to Claude.ai and the official Claude Code CLI only.
Users still have options: switch to a Claude API key (pay-per-token), or buy the new discounted extra usage bundles Anthropic is rolling out alongside this change.
Why it matters: This closes the biggest loophole in Anthropic's pricing model — and signals that the era of hacking premium AI subscriptions for unlimited agentic use is over.
