{"name":"vendor-risk-brief","description":"Vendor risk brief API for supplier vetting and vendor onboarding checks: assess a vendor or supplier domain before you sign a contract or grant system access. Pulls WHOIS/RDAP registration age, DNS records, TLS certificate health, DMARC/SPF/DKIM email authentication, a domain-wide email deliverability posture check, and detected tech stack into one procurement-ready risk brief. Composite: one call runs whois-lookup + dns-lookup + ssl-cert-info + dmarc-check + email-deliverability-check + tech-stack-detect in parallel (tech-stack-detect is optional, degrading if the homepage is slow or blocked) into {registration, dns, tls, email_auth, email_posture, tech_stack}. Use it as a vendor risk brief, supplier vetting API, or vendor onboarding due-diligence check.","price":"$0.06","method":"POST","input_schema":{"properties":{"domain":{"type":"string","description":"Vendor or supplier domain to assess, e.g. 'vendor.com'.
