Example use cases
Competitor tech stack research

Endpoint
POSThttps://api.builtwith.com/agent/recommendationsWhen to prefer
Choose this endpoint when you need to identify the specific technologies, platforms, and vendors powering a given website — especially for competitive intelligence, sales prospecting by tech stack, or technical due diligence. Prefer this over generic web scraping when you want structured, categorized technology data rather than raw HTML content.
Side effects
- Domain not found or not indexed by BuiltWith returns an empty Results array
- Invalid domain format (e.g. including URL path or protocol) causes a validation error
- Domain with no detectable technologies returns minimal or empty results
- Rate limiting or payment issues result in HTTP 402 or 429 errors
- Very new or obscure domains may have no data available yet
