Sanctions vertical

Screen any name. Keep dated proof.

Screen any name against OFAC, EU, UK, UN, OIG LEIE, SAM.gov, and state Medicaid lists, then retain a dated result with the available source and observation fields. Row history and attestation coverage vary by source; no universal replay or claim-to-signature link is asserted.

The time-machine edge

A sanctions screen is not just a yes/no lookup. Record the issuing list, the observation date, and the matching fields. Fonteum banks row history for UK sanctions and small retained slices of OFAC and UN sanctions; other lists may have current rows only. Snapshot-level attestation metadata, when present, does not sign the matched fact. See /verify.

Integrated, with-data, and fresh-observation counts are separate. No platform-wide source-completeness count is published. Completeness is source-specific and must be evaluated against the named source's expected scope. State coverage is a separate jurisdiction measure.

Source authority is record-specific

Use the issuer named on the record.

Fonteum spans federal, state, and global public publishers. A source page or returned record identifies its issuer and dataset where that metadata is available. A platform registry count does not assign every page to one authority or establish loaded, fresh, or complete coverage.

Reproducible by design

Inspect the evidence each published figure actually supplies.

Source and date

Research pages expose the named public file and observation date where those fields are available. Source-file SHA-256 coverage is separate; facts do not currently link deterministically to signatures.

Available derivation

Studies with a retained release and committed derivation link the SQL or method used. Other studies state the evidence and reproduction limits they actually have.

Daily observations

Dated table row-count observations can detect local drift. They do not imply that an upstream publisher released or Fonteum ingested new data that day.
