Overview
The Research API provides public access to aggregated data modeled from LouieAuto's AI simulation engine and public industry sources. LouieAuto is pre-launch — the Louie Network has zero dealers today, so this is not live dealer network data.
No authentication required. All endpoints are public and rate-limited to 100 requests/hour per IP.
