ReliaQuest

ReliaQuest is a Tampa-based, privately held cybersecurity company whose GreyMatter platform runs agentic AI security operations (detection, containment, investigation and response) on top of the security tools a customer already owns, connected through bidirectional APIs to 300+ technologies. Customers automate GreyMatter through the GreyMatter API, a single-endpoint GraphQL API (incidents, cases, tasks, detections, playbooks, DRP alerts, discover tasks, users, access groups and API keys) documented as a public Postman collection at apidocs.myreliaquest.com and authenticated with an X-API-KEY header. ReliaQuest also operates the Digital Shadows SearchLight Portal API (digital risk protection) acquired with Digital Shadows in 2022, whose reference is customer-only.

ReliaQuest publishes 1 API on the APIs.io network: GreyMatter API. Tagged areas include Cybersecurity, Security Operations, Threat Detection, Incident Response, and Threat Intelligence.

ReliaQuest’s developer surface includes engineering blog, documentation, API reference, changelog, FAQ, pricing, support, and 24 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/reliaquest: open an issue to ask a question, or submit a pull request to add artifacts.

    Authenticated with HTTP Basic credentials (an API key id and secret) and the vendor media type application/vnd.polaris-v38+json;
    resources include data breaches, data-breach usernames, DNS lookups, domain and IP WHOIS, search, intel threats, incidents
    and intel incidents. The API reference lives inside the portal behind a customer login, so no machine-readable contract
    is publicly reachable; the endpoint set here is read from ReliaQuest's own shadowline client on GitHub.
