How this service works

Full technology profile for a domain — tech stack, metadata, spend history, social links, company info, and detection dates across all subdomains and paths.

Output

A detailed breakdown of technologies detected on the queried domain, including technology names, categories, first/last detected dates, and optional attributes and metadata. The response can be filtered to live-only technologies, exclude PII such as emails and phone numbers, and hide dead links or text descriptions.

Example use cases

Example prompt

“Look up the full technology stack for stripe.com using BuiltWith — only show me live technologies and leave out any PII.”

When to prefer

Use this endpoint when you need a comprehensive, detailed technology profile of a specific domain — including historical detection data, technology attributes, and metadata. Prefer this over the Free Summary endpoint when you need full detail rather than a quick overview, and over the Lists endpoint when you want all technologies on one domain rather than all domains using one technology.

Side effects

Invalid or non-existent domain returns empty or error response
Domain with no BuiltWith data returns minimal or empty technology list
Malformed LOOKUP parameter causes API error
Invalid date format in FDRANGE or LDRANGE causes filtering failure
Rate limiting or quota exceeded returns HTTP 429 or similar error

Input
