Hunter.io OSINT integration

Find work emails at a domain, guess a person’s address, and verify deliverability.

Hunter.io Domain Search returns professional emails found for a website, Email Finder maps a name plus company domain to the most likely address, and Email Verifier checks deliverability. The index is crawled from the public web — about 150 million professional addresses — and Domain Search hits include where and when each address was found. SearchIn bills Domain Search and Email Finder at $0.20 and verification at $0.10, then renders the same cards as every other source on the desk.

Capabilities

What this integration is designed to return.

Domain Search — emails, titles, departments, confidence, and the public page and date each address was found (first 10 on this integration)

Email Finder — most likely work email from a person name and company domain, marked as sourced or as a domain-level guess

Email Verifier — deliverability status, SMTP flags, and web sources

Public-web index of about 150 million professional addresses, from about 650 million public sources, with about 30 million pages crawled a day

Async verifier jobs polled automatically when Hunter needs more time

How the Hunter.io integration works

What happens between pressing run and reading a result.

1Choose Domain, Name, or Email and select Hunter.io. A name search needs a person name plus the company domain — the UI collects first name, last name, and domain; the API query is Full Name example.com.
2Domain Search calls Hunter’s domain-search endpoint for the first page of emails (10 by default). Email Finder calls email-finder. Email Verifier calls email-verifier and may stay running until Hunter finishes SMTP checks.
3SearchIn bills $0.20 for Domain Search and Email Finder, and $0.10 for verification, then normalises emails, people, and verification flags.
4Hits become graph nodes so you can pivot an address into LeakRadar, DeHashed, or reverse WHOIS without retyping.

Data coverage

What the underlying dataset reaches.

Hunter builds its professional-email index from the public web: about 150 million addresses, about 650 million public sources, and about 30 million pages crawled a day. Domain Search returns each contact with where and when it was found. Email Finder says whether the address was found on a public page or guessed from public patterns at that domain. Sources that can no longer be found are labeled Removed, and contact or company data with no remaining public source is dropped after six months. People can claim an address and delete it; site owners can block the crawler with robots.txt.

Supported inputs & pricing

Prices are USD. LeakRadar includes 1,000 credential unlocks in the query price, then $0.50 per extra 1,000. OSINT Industries is $0.60 plus optional premium modules at $1.80. Other integrations are flat per query. Full SearchIn rates are on pricing.

Why run Hunter.io through OSINTverse

You can always buy Hunter.io directly. Here is what changes when the same data comes through SearchIn instead. Full write-up: OSINTverse vs Hunter.io.

Domain Search, Email Finder, and verification share one prepaid SearchIn wallet — $0.20 per search, $0.10 per verification.

The verifier’s 202 wait is polled for you, same as every other running SearchIn job.

Emails drop onto the case graph so the next pivot is a leak or WHOIS lookup, not a copy-paste into Hunter’s UI.

Hunter.io directly compared with Hunter.io through OSINTverse SearchIn
	Hunter.io directly	Through OSINTverse
Getting started	Hunter.io sells search credits and verification credits on its own plans, with a finder/verifier API you authenticate and paginate yourself.	Sign in, top up from $10, and run Hunter.io the same minute — no vendor contract, seat, or sales call.
What a query costs	Plan, credit pack, or contract pricing set by the vendor and paid up front.	Pay per query from your prepaid balance — Hunter.io starts at $0.10 for email lookups, with the exact price shown before you run it.
Failed lookups	Handled under the vendor's own credit and refund policy.	Automatically refunded to your wallet — a search that fails upstream after billing is not charged.
Output format	A vendor-specific response shape you normalise and render yourself.	Normalised result panels plus the raw JSON, returned by the same POST /v1/search contract as every other integration.
Cross-source work	Copy-paste between vendor dashboards to follow a lead into another dataset.	Results join one case graph, so you can pivot an entity into any of the other 16 integrations in a click.
Running it for a team	Per-seat or per-account access, billed and administered per analyst.	One shared team wallet with roles, provider allowlists, enforced MFA, and audit history — no per-seat fee.
Volume work	Script the vendor API yourself, including retries, polling, and rate handling.	Bulk search takes up to 50 queries across selected providers in one submission (max 100 jobs), with per-job status and partial-failure handling.

What every integration inherits

One wallet, no subscriptions

Top up prepaid USD from $10 and spend it a query at a time across all 17 integrations. No monthly fee, no seat count — and the balance never expires.

Failed searches are refunded

If an upstream provider errors or times out after the charge, the search is marked refunded and the money goes back to your wallet automatically.

One API for every source

The same POST /v1/search contract and x-api-key header work for every integration, so adding a source to your automation is a one-word change.

Cases and pivot graph

Results land in a named case you can reopen. Entities become graph nodes you can pivot from into any other integration without retyping.

Team wallets and controls

Share one balance with roles, provider allowlists, enforced MFA, and audit history — instead of buying a vendor seat for every analyst.

Exports built in

Download any result as JSON, CSV, or PDF, and export the case graph as PNG, SVG, entities CSV, or graph JSON.

Good to know

Constraints worth reading before you spend a query.

This integration returns the first Domain Search page (10 emails). Hunter may have more; extra pages are not auto-fetched.

Email Finder can return a guess built from public patterns at the domain, not a page that lists that address. Treat confidence and verification as leads, not proof.

Hunter removes contact and company data that has had no public source for six months, after labeling missing sources as Removed.

Hunter will not process some people who have asked not to be included (HTTP 451) — those lookups refund.

Going direct still makes sense at sustained high volume on a single source. Hunter.io sells search credits and verification credits on its own plans, with a finder/verifier API you authenticate and paginate yourself. Through SearchIn you trade that commitment for per-query pricing across 17 integrations.
