Example use cases

“We just got a signup from someone at linear.app — can you enrich their company domain and give me their tech stack, pricing tier, and any contact emails you can find so I can prioritize outreach?”
Competitive tech stack research
“I want to know what technologies Notion.so is running under the hood — can you pull their full tech stack breakdown along with a company summary and social links?”

Endpoint
GEThttps://preflight.agentdiet.dev/v1/enterprise-firmographics-api?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need comprehensive B2B company intelligence from a single domain lookup — particularly when you need tech stack signals alongside contact and firmographic data in one call. Prefer this over generic web scrapers when you want structured, agent-ready output with verified emails and social links without building your own extraction pipeline.
Side effects
- Unknown or unresolvable domain returns empty or partial results
- Private/internal domains with no public web presence may yield minimal data
- Rate limiting or payment failure (HTTP 402) if x402 micropayment is not properly handled
- Stale tech stack data if the company recently changed their stack
- Domains with heavy JavaScript rendering may reduce signal coverage
