Example use cases
GTM prospect tech stack research
“Before my sales call tomorrow, can you enrich linear.app and tell me what CRM, analytics tools, and marketing stack they're using, plus any contact emails you can find?”
B2B lead enrichment for outreach
“I have a list starting with notion.so — can you pull verified emails, LinkedIn and Twitter links, and a company summary so I can kick off an outreach campaign?”
Competitive technology intelligence
“Can you check what tech stack and pricing tiers are publicly detectable on figma.com? I want to understand their infrastructure and tooling for a competitive analysis report.”

Choose this endpoint when you need comprehensive B2B company enrichment from a single domain lookup, including tech stack detection, contact discovery, and firmographic summary in one call. Ideal for GTM agents, sales automation pipelines, and competitive research workflows that require more than just basic WHOIS or LinkedIn data. Best when you need 40+ technology signals alongside verified contact information without stitching together multiple data sources.
Side effects
- Domain not found or unresolvable — may return empty or partial data
- Private or parked domains with no detectable tech stack return minimal signals
- Rate limiting or payment failure (HTTP 402) if micropayment is not properly handled
- Malformed domain input may result in validation error
- Some email addresses may be unverifiable if domain has strict privacy protections
