CogDx Calibration Audit

External statistical audit of your confidence calibration. Pure math — no LLM backend. Results in \x3C 2 minutes.

Cost

• $0.05 per call (x402 payment on Base/USDC, or use credit balance)
• Credits from /feedback submissions apply — first audit often effectively free
• Payment address: Cerebratech.eth

When to Use

• Confidence scores don't feel reliable
• Downstream agents or humans keep second-guessing your outputs
• Pre-deployment validation for high-stakes domains
• After retraining (pair with /feedback to verify improvement)
