      Published under the digitalshadows GitHub org by Digital Shadows Ltd (author richard.gold@digitalshadows.com,
      Technical Tool License Agreement naming Digital Shadows Limited); Digital Shadows was acquired by
      ReliaQuest in 2022 and the API it wraps now answers with a ReliaQuest support address.

    note: >-
      Click-based CLI ("shadowline") wrapping https://portal-digitalshadows.com/api/ — commands
      cve_search, databreach_list, databreach_summary, databreach_username, domain_lookup, domain_whois,
      incidents, indicator, ipaddr_whois, setup_profile, threats. Requires a Digital Shadows Portal API key.
      A first-party client last touched in 2023 against a portal API that is still live is a currency
      signal in its own right.
not_found:
  - registry: pypi
    names_checked: [shadowline, reliaquest, greymatter, digitalshadows]
    note: >-
      `greymatter` and `searchlight` on PyPI belong to unrelated projects (a Selenium helper and OpenStack
      Searchlight); `greymatter-mcp` is a community, explicitly unofficial MCP server (see mcp/).
  - registry: npm
    note: no @reliaquest scope or reliaquest/greymatter package found
sdk_note: >-
  ReliaQuest publishes no SDK for the GreyMatter GraphQL API; the docs point developers at a Postman
  collection and GraphQL introspection. No `SDKs` pointer is emitted for GreyMatter. shadowline is a CLI
  for the legacy SearchLight API rather than an SDK, so no `SDKs` pointer is emitted for it either.
