Crene API — Developer Documentation

API ReferenceREST

Prediction intelligence via REST API. Real-time forecasts from 4 frontier AI models across macro, earnings, crypto, and policy events. Every prediction Brier scored and resolved against authoritative sources. Public endpoints for exploration, authenticated for bulk export.

Quick start
# Public — no auth needed
curl "https://api-get.crene.com/api/predictions/accuracy/"

# Divergence signals
curl "https://api-get.crene.com/api/predictions/edges/?min_edge=15"

# Prediction lifecycle + taxonomy
curl "https://api-get.crene.com/api/predictions/lifecycle/{question_id}/"

# Authenticated — bulk export
curl -H "X-API-Key: crn_..." \
  "https://api-get.crene.com/api/export/predictions/?output=csv&limit=500"
Authentication

Most endpoints are public with generous rate limits. For bulk exports and higher throughput, pass your key via the X-API-Key header.
