# Probabilistic Consensus Oracle

`POST https://humanmirror.fr/api/v1/consensus/verify/` receives exactly two software-agent signals and returns a deterministic normalized consensus metric.

Each signal declares a boolean state, confidence, reliability and optional weight. The engine converts each perception into an effective probability, aggregates weighted log-odds with an optional prior, then applies an asymmetric decision threshold:

`threshold = false_positive_cost / (false_positive_cost + false_negative_cost)`

The response includes probability of true/false, normalized verdict, contradiction and coherence scores, asymmetric expected losses and a SHA-256 proof digest.

The public test quota is three calls per 24-hour fingerprint. Further calls return HTTP 402 with `PAYMENT-REQUIRED`; paid retries send `PAYMENT-SIGNATURE` and receive `PAYMENT-RESPONSE` after successful Base/USDC settlement.
