StoreSignal

The problem

Every Shopify store leaves a public footprint. The apps it runs. The payment stack at checkout. The CDN and security headers. The products it sells.

Researching that by hand across hundreds of stores is tedious, and brittle scraping scripts break the moment a theme changes.

What StoreSignal is

A developer API that returns clean, structured profiles for any Shopify store, derived from publicly accessible data. No login required. No private data accessed. Indexed across 19,647 stores with a 278-app catalog.

What you get back

• → Installed apps and theme, from the store's public footprint
• → Payment stack, CDN, and security headers
• → AI-classified industry and growth stage
• → Revenue estimates and product catalog summaries
• → Head-to-head store comparison
