Anthropic ended free subscription usage for OpenClaw and all third-party Claude Code harnesses, forcing separate pay-as-you-go billing starting April 4.
Anthropic notified Claude Code subscribers via email that third-party tools like OpenClaw can no longer draw from subscription limits, effective April 4 at noon Pacific. Users must now pay separately via a pay-as-you-go model for any third-party harness usage. Anthropic head of Claude Code Boris Cherny cited unsustainable usage patterns as the driver. The timing coincides with OpenClaw creator Peter Steinberger announcing he's joining OpenAI, with Steinberger publicly accusing Anthropic of copying features before locking out open-source competitors.
If you're running OpenClaw or any third-party harness against Claude Code's subscription tier, your workflow is now broken or about to get expensive. Anthropic explicitly says this policy extends to ALL third-party harnesses, not just OpenClaw — so any custom tooling or orchestration layer you've built on top of Claude Code subscriptions is at risk. Pay-as-you-go API pricing at scale hits very differently than a flat subscription.
Pull your Claude Code usage logs from the last 30 days and calculate your token volume — if you're running agentic loops via any third-party harness, price it against Anthropic's API token rates to get your real monthly cost before it hits your card.
Suggested exercise · not independently tested. Access requirements and costs may vary.
Open your terminal and run: pip install anthropic then open a Python file
Paste: import anthropic; client = anthropic.Anthropic(api_key='YOUR_KEY'); print(client.beta.usage.get()) — or check your Anthropic console at console.anthropic.com/usage for a breakdown of token consumption by day
Multiply your average daily input+output tokens by the current API rate ($3/$15 per million for Claude Sonnet) to get your projected monthly bill under the new model
