Example use cases
GTM research on a sales prospect
“I'm preparing for an outbound call to linear.app — can you pull their firmographic profile, what technologies they're using, any verified contact emails, and their pricing structure?”
Tech stack competitive analysis
“What tech stack is notion.so running? I need to know their key tools, any social links, and a company overview to prep my competitive analysis.”
Enriching a B2B lead list
“I've got a lead for salesforce.com — can you enrich it with verified emails, social profiles, tech signals, and a company summary so I can personalize my outreach?”

Endpoint
GEThttps://whale-momentum.agentdiet.dev/v1/firmographics?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, broad firmographic snapshot of a B2B company from just their domain — especially when you want a bundle of verified contacts, social links, tech stack signals, and pricing info in a single call rather than stitching together multiple point solutions. Prefer this for GTM agents, sales enrichment workflows, and competitive research pipelines that operate on company domains.
Side effects
- Invalid or unresolvable domain returns an error or empty result
- Private/obscure domains with no public footprint may return sparse data
- Rate limiting or payment failure (HTTP 402) if USDC payment is not properly attached
- Stale data if the company recently changed their tech stack or contacts
- Malformed domain input (e.g. including path or query string) may fail validation
