Hunter.io
Find professional emails at a domain, guess a work address from a name, and verify deliverability.
Hunter.io on SearchIn runs Domain Search, Email Finder, and Email Verifier against the same prepaid wallet as every other source.
Capabilities
- Domain Search — emails found at a website, with titles, departments, confidence, and public sources
- Email Finder — most likely work email from a person name and company domain
- Email Verifier — deliverability status and SMTP flags
- Automatic polling when the verifier needs more time (HTTP 202)
What you get back
- Email table with confidence, personal vs generic type, title, and verification
- Finder person card with score and sources
- Verifier status flags (disposable, webmail, MX, SMTP)
UI workflow
Choose Domain, Name, or Email.
Select Hunter.io. For Name, enter first name, last name, and the company domain.
Review emails or the verification card, then pivot hits into leak or WHOIS providers.
Sample queries
| Input type | Query | Notes |
|---|---|---|
domain | stripe.com | First page of emails found at the domain |
name | Alexis Ohanian reddit.com | Email Finder — full name then company domain |
email | [email protected] | Deliverability verification |
API name queries use the same Full Name example.com format. You can also write Jane Doe @ example.com.
Pricing
domain $0.20 · name $0.20 · email $0.10
Best for
- Mapping [email protected] during an investigation
- Confirming a guessed work email before a deeper people search
- Checking whether an address is disposable, catch-all, or deliverable
How it works & why through OSINTverse
How the request runs
- 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.
Coverage. Hunter’s public-web and inferred professional email index: addresses found at a domain, name-to-email guesses with confidence, and SMTP-backed deliverability checks.
Why route Hunter.io through OSINTverse
- ·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 | 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 13 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. |
One wallet, no subscriptions
Top up prepaid USD from $10 and spend it a query at a time across all 14 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
- This integration returns the first Domain Search page (10 emails). Hunter may have more; extra pages are not auto-fetched.
- Email Finder can return an inferred address. Treat confidence and verification as leads, not proof.
- Hunter will not process some people who have asked not to be included (HTTP 451) — those lookups refund.
API example
$0.10 per query. Live runs charge the active workspace wallet — the same rates as the dashboard.
curl -X POST "https://apiv1.osintverse.com/v1/search" \ -H "Content-Type: application/json" \ -H "x-api-key: ov_your_api_key" \ -d '{"provider":"hunter","input_type":"email","query":"[email protected]"}'Invalid provider + input_type pairs return HTTP 422. Confirm combinations with GET /v1/providers or the pricing matrix. Hunter name queries must include a company domain.
