Free. Indicator-feed freshness and the CVE ids and ransomware groups currently cached for cve_intel and group_intel.
cve_intel for up to 50 CVEs in one call. Charged only if at least half are cached; otherwise an error lists the covered ids (not charged). Costs $0.50 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure returns an error and is not charged.
Everything an agent needs to prioritize one CVE: CVSS, affected vendors/products, vendor advisories, CISA KEV status and known ransomware use, EPSS, recorded public exploit repositories, an AI-generated attack flow with ATT&CK technique ids (flagged as AI-generated) and suggested MITRE D3FEND countermeasures. CVEs not cached yet return an error (queued, not charged); check cve_status (free) first. Costs $0.03 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure returns an error and is not charged.
Free. CISA KEV status (date added, due date, known ransomware campaign use, required action), EPSS when known, and whether paid cve_intel detail is cached for this CVE.

Added "bulk_vendor_check" and "watch_status" (7 tools before, 9 now)
Check up to 100 vendors (domains or company names) for ransomware leak-site claims in one call: per vendor, matching claims (group, dates, sources), claim count and groups. Raw claims only; use vendor_risk_report for risk levels, a summary and actions. Every result is an unverified claim from a criminal leak site, not a confirmed breach; found=false is not proof of absence. Fails (not charged) if the source is down for more than 25% of vendors. Read-only. Costs $0.50 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure returns an error and is no…
Free. Status of a paid vendor watch (created with HTTP POST /v1/watch): items, expiry, last check, last webhook delivery.
Added "vendor_risk_report" (6 tools before, 7 now)
Build a third-party ransomware risk report for up to 100 vendors (domains or company names). For each vendor: matching leak-site claims (group, claimed and first-observed dates, sources), a risk level (high = claim in the last 90 days, elevated = last 12 months, historical, none_found, unknown) and follow-up actions; plus a portfolio summary with priority vendors and the groups involved. Use it for vendor reviews and audits; use batch_exposure_check for a cheaper raw check of up to 25 domains. Every result is an unverified claim from a criminal leak site, not a confirmed breach; none_found is…
Changed the definition of "batch_exposure_check", "group_profile", "lookup_victim" and 3 more
Vendor-risk batch: checkCheck up to 25 vendor or supplier domains in one call for ransomware leak-siteclaims.claims, for third-party-risk reviews. Returnsper-domainoneresultsresult per domain (found, claim count, claims with group, dates,and sources). Domains only; use lookup_victim for company names. At most 15 claim records are read per batch, so a domain with many matches is marked partial. Every result is an unverified claim from a criminal leak site, not a confirmed breach;
Added "batch_exposure_check" (5 tools before, 6 now)
Vendor-risk batch: check up to 25 supplier domains in one call for ransomware leak-site claims. Returns per-domain results (found, claims with group, dates, sources). Every result is an unverified claim from a criminal leak site, not a confirmed breach; found:false is not proof of absence.

Threat-hunting profile of one active ransomware group: total and recent leak-site listings with a momentum status, reported tools, malware, campaigns, ATT&CK techniques and CVEs co-mentioned in public reporting (co-mention, not attribution), recent headlines and suggested D3FEND countermeasures. Use group_profile for its claim sample. Uncached groups return an error (queued, not charged). Costs $0.05 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure returns an error and is not charged.
Same as indicator_check for up to 100 domains or IPv4 addresses in one call (one flat price). Costs $0.25 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure returns an error and is not charged.
Check one domain (or its parent domains) or IPv4 address against ThreatCluster's high-confidence 30-day IOC feed: is it listed as attacker infrastructure (C2, phishing, malware delivery) in recent threat reporting? Returns listed/not_listed, match type, reason, linked reports and clusters. Use it before opening a link, in email triage or SOC enrichment. Not listed is not proof of safety. Served from an hourly cache; a stale feed returns an error and is not charged. Costs $0.01 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure returns an error…
