SecurityTrails OSINT integration

Current DNS records and subdomain inventory from SecurityTrails.

SecurityTrails on the free API returns live DNS (A, AAAA, MX, NS, TXT) and a subdomain list for a hostname. WHOIS, reverse WHOIS, reverse IP, and historical lookups are not included on this plan. SecurityTrails’ own site publishes a wider corpus — 630 million domains, 2.6 billion hostnames, 4.2 billion historical WHOIS records, and 10.19 trillion historical DNS lookups — which this integration does not return.

How the SecurityTrails integration works

What happens between pressing run and reading a result.

1Choose domain and select SecurityTrails.
2SearchIn pulls the current DNS record set — A, AAAA, MX, NS, and TXT — with first-seen dates and shared-IP counts.
3It also requests the subdomain inventory for that hostname.
4Results render as a DNS overview plus a filterable subdomain list, with raw JSON kept on the record.

Data coverage

What the underlying dataset reaches.

SecurityTrails publishes 630 million domains, 2.6 billion hostnames, 4.2 billion historical WHOIS records, and 10.19 trillion historical DNS lookups. This integration returns current DNS and the first page of subdomains from the free API.

Data sources

The totals below are SecurityTrails’ published corpus. SearchIn calls the free API: current DNS records and the first page of subdomains for one hostname.

What a SearchIn query returns

A SearchIn query returns the live DNS set and the first page of subdomains.

Current A, AAAA, MX, NS, and TXT records, with first-seen dates and shared-IP counts.

The first page of the subdomain inventory for that hostname.

WHOIS, reverse WHOIS, reverse IP, and historical DNS are outside this integration.

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 SecurityTrails through OSINTverse

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

No SecurityTrails plan to buy — run a one-off DNS and subdomain check for $0.50.

DNS records and subdomains render as a filterable inventory next to your WHOIS and breach results.

Subdomain hits become graph nodes you can pivot into Whoxy, WhoisXML, or breach providers.

SecurityTrails directly compared with SecurityTrails through OSINTverse SearchIn
	SecurityTrails directly	Through OSINTverse
Getting started	SecurityTrails gates WHOIS, reverse lookups, and historical data behind paid plans; free keys cover current DNS and a first page of subdomains.	Sign in, top up from $10, and run SecurityTrails 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 — SecurityTrails starts at $0.50 for domain 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 runs on the free SecurityTrails surface: current DNS and the first page of subdomains only.

WHOIS, reverse WHOIS, reverse IP, and historical DNS are not available here — use Whoxy or WhoisXML instead.

Going direct still makes sense at sustained high volume on a single source. SecurityTrails gates WHOIS, reverse lookups, and historical data behind paid plans; free keys cover current DNS and a first page of subdomains. Through SearchIn you trade that commitment for per-query pricing across 17 integrations.

Access via SearchIn UI

Run the integration without leaving the dashboard.

Open SearchIn and choose Domain.
Select SecurityTrails as the provider.
