API · JUN 2026

Public proof layer API.

Read the proof layer behind Crene thesis review objects as JSON. Public endpoints expose the resolved-event corpus, current active forecasts, thesis maps, factors, scenarios, model leaderboard, category coverage, and calibration metrics. The write endpoint for arbitrary forward-looking questions is available through private review access.
Quick start

The Probability endpoint, write access for arbitrary forward-looking questions, is available through private review access. Teams can request access below.

Authentication

The Probability endpoint requires a key passed as the X-API-Key header. Read endpoints over the Crene corpus remain public.

Resolved outcomes are tied to named sources, including government data, central banks, SEC filings, primary financial reporting, and authoritative secondary reporting where appropriate. Full provenance is stored per event. How resolution works
