How this service works

RelayShield Landing Site

Output

Returns a JSON object with: the queried domain, a boolean indicating whether it appears on known ransomware victim lists, and an integer count of pre-ransomware credential exposures associated with that domain.

Example use cases

Vendor due diligence ransomware screening

“Before we onboard supplierco.com as a vendor, can you check if they've ever appeared on a ransomware victim list and how many pre-breach credentials are associated with their domain?”

Incident response domain triage

“We're investigating a potential breach — can you check if contoso.com is on any ransomware victim lists and whether there were credential leaks leading up to it?”

Portfolio company cyber risk audit

“Run a ransomware risk check on each of these portfolio company domains — start with techstartup.io — and tell me if any are on victim lists or have pre-ransomware credential exposures.”

Endpoint

When to prefer

Use this endpoint when you need a fast, pay-per-query ransomware victim list check against a specific domain without committing to a subscription threat intelligence platform. It is especially useful for one-off vendor assessments, incident triage, or enriching domain risk profiles in automated workflows where you only need the victim-list status and pre-ransomware credential count rather than a full threat report.

Side effects

Invalid or malformed domain input returns an error
Domain not found in database returns on_victim_list: false with zero credential count (may be a true negative or data gap)
Payment failure via x402 protocol blocks the request
Rate limiting on high-volume queries
Network timeout if upstream threat intel feeds are slow
