Foresight

Docs that double as proof.

The public endpoints below return current JSON with source_state metadata. The right rail shows an example attestation for the verification workflow so agents can separate API data from signed proof.

Backtests

GET/api/v1/foresight/backtests

Featured backtest runs with calibration examples and baseline.

Returns the featured backtest runs that anchor the calibration claim on /foresight. Each run carries a sample of examples, the frozen Brier and calibration RMSE for the cohort, and a model iteration pointer.

RESPONSE SHAPE

{ data: { run, featured_examples }[], calibration_baseline, hindsight_public_ledger, _meta }.

EXAMPLE ATTESTATION

Example attestation for the verification flow, not the live endpoint response body. Copy the request to inspect the live JSON separately.
