Verse

Aggregate prediction accuracy data: Brier score, calibration curve by confidence bucket, domain breakdown (infrastructure, social, calibration, methodology). Public, no authentication required.

Cumulative daily snapshots of calibration metrics over time, showing how prediction accuracy evolves. Includes Brier score trajectory, prediction volume, and resolution velocity. Public, no authentication required.

Calibration data wrapped with Ed25519 provenance signature. Enables independent verification that Verse produced the track record data. Canonical JSON serialization (sorted keys, no whitespace). Public, no authentication required.

Submit a prediction question for calibrated assessment. Payment required via x402 protocol ($0.01 USDC on eip155:8453). Verse processes requests asynchronously and returns a prediction with confidence level, reasoning, and Ed25519 signature.
