# HackNotice > External threat-intelligence and cyber-risk platform (Austin, Texas, founded 2018). Monitors > ransomware groups, infostealer logs, breached data, dark-web marketplaces and hacker forums, and > matches that intelligence against the domains, employees, customers and vendors a company asks it > to watch. Four services: first-party domain monitoring, third-party vendor risk monitoring, > end-user credential monitoring, and threat research — plus AI-assisted vendor security assessments.

Call the API to learn what happened. - Destinations: Slack incoming webhook, Splunk HTTP Event Collector, ticketing systems via alert email address. - No AsyncAPI document, no payload schema, no webhook signature. ## Known gaps (measured, not inferred) - No OpenAPI published by HackNotice. - No /.well-known document on any host; no security.txt; no OAuth/OIDC metadata. - No A2A agent card. - No status page, no SLA, no API changelog. - No deprecation policy, though a "Deprecated" folder exists in the published collection. - No idempotency contract, and no reversal operation or window for any destructive operation. - No published compliance program, trust centre or vulnerability-disclosure policy. - Errors are a flat {"message": "..."} string, not RFC 9457. - No STIX, TAXII, MISP, OpenC2 or CVE/CVSS interchange in the contract. ## Company - Website: https://hacknotice.com/ - Pricing: https://hacknotice.com/pricing/ — Starter $15,000/yr (50 vendors), Growth $30,000/yr (150), Business $70,000/yr (500), Enterprise $120,000/yr (1,000) - Blog: https://hacknotice.com/category/blog/ (RSS: https://hacknotice.com/feed/) - Terms: https://hacknotice.com/businesstandc/ | Privacy: https://hacknotice.com/privacy/ | Use policy: https://hacknotice.com/use-policy/ - Support: support@hacknotice.com --- This profile is maintained independently by API Evangelist (https://apievangelist.com) from publicly reachable material.
