SignHunter API

Real-time contractor activity data for platforms and distributors.

Our API exposes contractor sign sightings across metro areas. Every sign is a contractor actively working a job site — actively purchasing materials, actively servicing a neighborhood. Query by zip code, category, or radius. Get activity summaries, contractor directories, and real-time webhooks when new signs appear in your target areas.
