How this service works
Verified B2B lead packs and per-lead enrichment lookups for agents. $0.01 per lookup or pack (demand probe). USDC on Base via x402. No account, API key, or subscription.
Output
Returns the company domain, detected email address patterns (e.g. '{first}.{last}'), whether MX records were found, whether the domain is a catch-all, and any additional signals — all as JSON.
Example use cases
Cold outreach email construction
“I'm about to reach out to a contact at stripe.com — can you figure out what email format they use there, like first.last or first_last, so I can guess their address?”
Pre-campaign domain validation
“Before I launch my outreach campaign targeting hubspot.com contacts, can you check what email pattern they use and whether their domain is a catch-all?”
B2B prospecting automation
“I have a list of company domains I'm prospecting — start with shopify.com and tell me their email naming convention and whether MX records are set up.”
Technical details
Endpoint
GEThttps://scout-packs-production.up.railway.app/email-pattern?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to infer the email naming convention for a specific company domain before constructing or validating B2B contact emails. It is especially useful for sales automation and outreach agents that need to guess individual email addresses from a known name and domain, without requiring a full contact database subscription. Prefer this over general email verification tools when the goal is pattern discovery rather than validating a specific known address.
Side effects
- Domain not recognized or too obscure to infer a pattern — patterns array returns empty
- No MX records found — mx_found returns false
- Domain is a catch-all — catch_all_unknown returns true, making pattern-based guessing unreliable
- Payment not completed via x402 — 402 response returned before data is delivered
- Invalid or malformed domain query parameter — request rejected
