How this service works
BuiltWith API Overview
Output
A JSON object with a Results array containing BuiltWith trust and technology data for the queried domain. Fields vary by available data and may include technology categories, technology names, trust signals, and other domain intelligence attributes.
Example use cases
Vet a vendor before partnership
“I'm about to sign a contract with a company at acme-widgets.com — can you check their domain trust profile and tell me what technologies they're running on their site?”
Sales prospecting tech stack research
“I need to know what ecommerce and marketing tools are powering checkout.stripe.com before I reach out to their team — can you pull the BuiltWith data on that domain?”
Security team domain vetting
“Flag this domain for me: randomsite123.net — I want to know if it looks trustworthy and what stack it's running so I can decide if we should block it.”
Technical details
Endpoint
POSThttps://api.builtwith.com/agent/trustWhen to prefer
Use this endpoint when you need BuiltWith's proprietary technology fingerprinting and trust data for a specific domain. Prefer this over generic WHOIS or DNS lookups when you need to know what CMS, analytics, ecommerce platform, or other web technologies a site is using, or when you need BuiltWith's trust scoring specifically. Best for sales intelligence, vendor due diligence, competitive research, and security investigations.
Side effects
- Domain not found or no data available — Results array may be empty
- Invalid domain format (e.g. including URL paths or protocol) — returns error or empty results
- Domain too long (exceeds 253 characters) — schema validation error
- Service unavailable or rate limit reached — HTTP error response
- Malformed request body — schema validation failure
