Coverage At A Glance
Indexed Sources
Source metadata shows record volume, indexed date, and searchable fields before researchers run a search. Public and private datasets are validated before they are added to the index.
Research Workflow
Use validated source coverage, field-aware search, and reviewed access to move from exposure checks into response work.
See source names, record counts, and indexed dates before deciding whether to run a deeper search.
Public and private leak sources come from vetted researcher submissions and automated extraction, then pass provenance and structure checks before ingestion.
Search by email, email wildcard, username, phone, IP, password hash, and other exposed fields when the dataset supports it.
Move from raw exposure checks into triage, reporting, and follow-up without leaving the platform.
Accounts are reviewed so the tool stays aligned with legitimate security research and response work.
Use API reference docs and MCP setup guides to plug breach checks into internal research tooling.
