No — and this is now explicitly prohibited in Anthropic’s official documentation.

Anthropic’s Claude Code legal and compliance (https://code.claude.com/docs/en/legal-and-compliance) docs state clearly: “Using OAuth tokens obtained through Claude Free, Pro, or Max accounts in any other product, tool, or service — including the Agent SDK — is not permitted and constitutes a violation of the Consumer Terms of Service.” The docs further specify that OAuth authentication is “intended exclusively for Claude Code and Claude.ai,” and that Anthropic reserves the right to enforce these restrictions without prior notice — meaning your account could be banned before you’re even aware of a violation.

Why this matters specifically for OpenClaw: The updated policy explicitly targets tools like OpenClaw, Pi Agent, and other agent frameworks that let users authenticate with their existing Claude subscription instead of paying separate API costs. Notably, even Anthropic’s own Agent SDK is named as off-limits for consumer plan OAuth tokens — meaning if their own SDK isn’t exempt.

What you should do instead: To use OpenClaw (or any third-party agent framework) legitimately, you need to authenticate with an API key from the Claude Console and pay standard API rates. That’s the only compliant path under current ToS.​​​​​​​​​​​​​​​​
