How this service works
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://x402-audit.agentdiet.dev/v1/enterprise-firmographics-api)
Output
Returns a structured object containing verified contact emails, social profile links, a curated list of 40+ detected tech stack signals, pricing tier details, and a company summary — all derived from the provided domain.
Example use cases
GTM outbound lead research
“I'm building an outbound list — can you enrich these domains for me, starting with hubspot.com? I need verified emails, their tech stack, and a company summary so my reps know what tools they're already using.”
Competitive tech stack analysis
“What tech stack is figma.com running? I want to know their infrastructure, analytics tools, and any third-party integrations — pull the full 40-signal tech breakdown.”
SaaS pricing intelligence
“Can you look up the pricing tiers and company summary for linear.app? I'm trying to understand how they structure their plans before pitching them a partnership.”

Endpoint
GEThttps://x402-audit.agentdiet.dev/v1/enterprise-firmographics-api?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a broad, all-in-one B2B company enrichment covering contacts, tech stack, social presence, and pricing in a single call — especially useful for GTM agents, sales automation pipelines, or competitive research workflows where breadth of signal per domain matters more than deep specialization in any one category.
Side effects
- Domain not found or invalid — returns empty or error object
- Domain exists but has no detectable tech stack — partial results returned
- Email verification fails for private/obscured domains
- Rate limit or payment authorization failure via x402 protocol
- Newly registered domains may return minimal firmographic data
