Domain intelligence

WhoisXML OSINT integration

Last-known WHOIS, reverse WHOIS, and reverse IP from Domain Research Suite.

WhoisXML Domain Research Suite returns the latest defined WHOIS fields (including values that are redacted on the live record), a history archive count, reverse WHOIS by email or registrant name, and domains hosted on an IP. WhoisXML’s published figures, measured 9 July 2026, include 28.7 billion+ WHOIS records and 1.2 billion+ domains tracked historically.

How the WhoisXML integration works

What happens between pressing run and reading a result.

1Choose domain, email, name, or IP and select WhoisXML.
2Domain queries read Domain Info for the last-known WHOIS fields, including values now hidden on the live record.
3SearchIn reports the WHOIS history archive count without pulling a full history dump.
4Email and name run reverse WHOIS; IP runs reverse IP to list domains hosted on that address.

Data coverage

What the underlying dataset reaches.

WhoisXML measured these figures on 9 July 2026: 28.7 billion+ WHOIS records, 1.2 billion+ domains tracked historically, 374 million+ active domains, and 7,596+ TLDs. SearchIn queries last-known WHOIS, the history archive count, reverse WHOIS, and reverse IP.

Data sources

SearchIn uses WhoisXML Domain Research Suite for last-known WHOIS, a history count, reverse WHOIS, and reverse IP. The totals below are WhoisXML’s published coverage, not a count of rows one SearchIn query returns.

What a SearchIn query returns

A SearchIn query uses Domain Research Suite WHOIS, reverse WHOIS, or reverse IP.

A domain query returns last-known WHOIS fields, including values that are redacted on the live record, plus a history archive count.

Email and name queries return domains tied to that registrant. An IP query returns domains hosted on that address.

SearchIn does not pull a full WHOIS history dump, and it does not call WhoisXML DNS, subdomain, or threat-intel products.

Last-known values can lag the current live record.

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 WhoisXML through OSINTverse

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

Last-known WHOIS surfaces contacts that are redacted on the live record, flagged with a clear “now redacted” badge.

You get the history archive count without paying for a 50-credit full history dump.

One flat SearchIn charge per query instead of reconciling a pooled DRS credit balance across products.

WhoisXML directly compared with WhoisXML through OSINTverse SearchIn
	WhoisXML directly	Through OSINTverse
Getting started	WhoisXML bills Domain Research Suite in pooled DRS credits shared across many products, where a single full WHOIS history dump alone costs 50 credits.	Sign in, top up from $10, and run WhoisXML 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 — WhoisXML starts at $0.40 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.

Last-known values can lag the current live record.

Reverse WHOIS and reverse IP are only as complete as the DRS index.

Going direct still makes sense at sustained high volume on a single source. WhoisXML bills Domain Research Suite in pooled DRS credits shared across many products, where a single full WHOIS history dump alone costs 50 credits. Through SearchIn you trade that commitment for per-query pricing across 17 integrations.

Access via SearchIn UI
