How this service works
Email lookup. Hunter's real status (valid, accept_all, unknown), found vs inferred, sources. $0.08, charged only when an address is returned.
Output
Returns the discovered or inferred email address for the named person at the given domain, along with Hunter's deliverability verdict (valid, accept_all, or unknown), a flag indicating whether the address was directly found or algorithmically inferred, and the sources that corroborate it. Only charged when an address is actually returned.
Example use cases
Sales lead email enrichment
“I have a prospect — Marcus Rivera at databridge.io — can you look up his work email and let me know if it's confirmed valid or just a catch-all?”
Outreach list verification
“Before I send cold emails, can you find and validate the email address for Sarah Chen at globalventures.com? I only want it if it was actually found, not guessed.”
CRM contact data gap filling
“We have a contact in our CRM — Tom Hendricks at northstarcorp.com — but no email. Can you look up his address and tell me the deliverability status and where it came from?”
Technical details
Endpoint
POSThttps://prospect-intelligence.prospectintel.workers.dev/v1/email?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to find a specific individual's professional email address given their name and employer domain, especially when you want Hunter's authoritative deliverability classification (valid vs accept_all vs unknown) and provenance (found vs inferred). Ideal for sales prospecting, CRM enrichment, and outreach workflows where email quality and sourcing transparency matter. The pay-per-result pricing ($0.50 only when an address is returned) makes it cost-efficient for bulk prospecting.
Side effects
- No email found for the given name and domain — no charge, empty result
- Domain not recognized or no data coverage — returns null result
- Ambiguous name match — may return best-guess inferred address with lower confidence
- Network timeout or upstream Hunter API unavailability — service error
- Invalid domain format in input — validation error
