dario uses your own OAuth token to access your own subscription. It doesn't bypass any limits — it ensures your requests are correctly classified under the budget you already paid for.

Without the billing tag, third-party tools get silently reclassified from your plan allocation to overage (pay-per-token) after ~1 hour. You're not getting free access — you're getting charged extra for access you already paid for.

The fingerprint injection exists because Anthropic's infrastructure uses it to route billing. If they exposed a proper API for Max subscribers, this wouldn't be necessary.
