Extracts verified emails, social links, 40+ tech stack signals, pricing tiers, and company summary for GTM & research agents. (Live x402 v2, IETF MPP & MCP endpoint at https://mcp-security.agentdiet.dev/v1/enterprise-firmographics-api)

Returns a structured object containing verified email addresses, social profile links, 40+ detected tech stack signals (e.g. analytics, CRM, CDN, frameworks), pricing tier indicators, and a company summary — all derived from the provided domain.
Example use cases
Pre-call sales research on a prospect
“Before my call with the Notion team tomorrow, can you enrich notion.so and tell me what tools they're running in their stack, who I might be able to email, and what their pricing looks like?”
GTM agent lead qualification pipeline
“I have a list of company domains from inbound signups — start with linear.app and give me their tech stack signals, verified emails, and a company summary so I can score and route the lead.”
Competitive tech stack intelligence
“Can you look up figma.com and tell me every major technology, framework, or SaaS tool they're using, along with any public contact info or social profiles you can find?”

Endpoint
GEThttps://mcp-security.agentdiet.dev/v1/enterprise-firmographics-api?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single-call enrichment of a B2B company domain that combines firmographics, tech stack detection, and contact data in one response. It is particularly well-suited for GTM agents, sales automation pipelines, and research agents that need to qualify leads without stitching together multiple specialized APIs. Prefer it over generic web scrapers when you need structured, signal-rich company intelligence including 40+ tech stack categories.
Side effects
- Unknown or unresolvable domain returns empty or minimal results
- Private/parked domains with no detectable web presence may yield no tech signals
- Rate limiting or payment failure (HTTP 402) if x402 USDC micropayment is not properly handled
- Malformed domain input (e.g. missing TLD) may cause a validation error
- Some fields (e.g. verified emails) may be absent for companies with strong privacy posture
