How this service works
Identity security, threat monitoring and intelligence for the agentic AI era. TAP verifier for agentic commerce, MCP Proxy Firewall for AI agents, and threat intelligence APIs backed by 725K indicators across 129 monitored marketplaces.
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.”
Technical details
Endpoint
POSThttps://api.relayshield.net/v1/payg/ransomware-risk?utm_source=zero.xyzWhen 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
