Likely Buyers
This page is a product preview for comparing likely buyers, source coverage, and first API shapes.

Initial Data Scope
The first buyer-ready workflow should keep the source coverage narrow.
- One-source NHTSA complaints cache by make, model, model year, component, filing date, and incident date first.
- Daily complaint trend snapshots before broader VIN, recall, warranty, or marketplace integrations.
- No safety defect determination, vehicle-history report, repair advice, legal advice, insurance underwriting decision, or recall-completion workflow.
