  title: HackNotice Deprecated API
  version: '2026-08-22'
  summary: External threat-intelligence API for first-party, third-party and end-user breach monitoring, threat research and vendor assessments.
  description: 'HackNotice''s REST API over its external threat-intelligence platform: credential and breach alerts for first-party domains, third-party vendors and end users; dark-web / hacker-forum research search; and AI-assisted vendor security assessments.


    PROVENANCE: this document was DERIVED by API Evangelist from HackNotice''s own published Postman collection "HackNotice-API", reached at https://api-docs.hacknotice.com (HTTP 301 -> https://documenter.getpostman.com/view/806684/2sBXiri7pT), linked from HackNotice''s help centre article "API". Paths, methods, parameters, request bodies and tags are transcribed from that collection; nothing was invented. Concrete record ids in the collection''s example URLs were templated into path parameters, and every token-shaped example value was redacted.


    HackNotice publishes a rate limit of 1 query per second, and states that API access is granted to approved accounts only after a 30-minute consultation call.'
