How this service works
Fetch a public website with private-network blocking and report transparent heuristic technology signatures from markup and headers.
Output
A JSON object containing the queried domain, categorized arrays of detected technologies (frontend, backend, hosting, analytics, marketing), any additional technology categories found, and a numeric confidence score (0–1) indicating how reliable the detection is.
Example use cases
Competitor tech due diligence
“I'm evaluating a competitor — can you pull the full technology stack for shopify.com? I want to know their frontend framework, backend, hosting, and any analytics or marketing tools they use.”
Sales prospecting tech profiling
“Before my sales call, can you check what tech stack notion.so is running on, especially what CRM or marketing tools they use? I want to tailor my pitch.”
Startup investment research
“I'm researching a startup at linear.app before investing — can you detect what technologies they use for their frontend, backend, and hosting, and give me a confidence score on the findings?”
Technical details
Endpoint
GEThttps://ai-data-marketplace-1042299154756.us-central1.run.app/api/v1/tech_stack_lookupWhen to prefer
Use this endpoint when you need a structured, categorized breakdown of a website's technology stack — including frontend, backend, hosting, analytics, and marketing layers — with a confidence score. Prefer it for competitive intelligence, sales prospecting enrichment, or due diligence workflows where you need machine-readable tech profiles per domain. It is distinct from raw web scraping because it interprets detected signals into named technology categories rather than returning raw HTML or headers.
Side effects
- Unknown or very new domain returns empty technology arrays with low confidence score
- Private or obscured tech stacks (e.g. behind Cloudflare proxies) may yield incomplete or inaccurate results
- Invalid domain format returns an input validation error
- Domain with no public web presence returns minimal data
- Payment failure via x402 returns HTTP 402 and the call is not processed
