Sales prospecting tech qualification

“I need to know if hubspot.com is running Salesforce or any CRM-related technologies on their site. Can you check their tech stack and show me only live technologies?”

When to prefer

Choose this endpoint when you need authoritative, comprehensive technology stack data for a specific domain backed by BuiltWith's database of 100M+ websites. It is ideal when you need structured, filterable technology profiles including historical detection dates, and when you are willing to pay per-lookup via the x402 micropayment protocol. Prefer this over scraping or manual inspection when you need reliable, categorized tech stack intelligence for competitive analysis, sales prospecting, or market research.

Side effects

Invalid or unresolvable domain returns empty or error data
Domain not indexed in BuiltWith database returns no technology results
Malformed FDRANGE or LDRANGE date format causes filter failure
Payment failure via x402 protocol results in request not being processed
Rate limiting or quota exhaustion on the underlying BuiltWith API
