v1Five-safeguard screening engine

Sanctions, PEP & adverse-media screening you can prove

Sub-second screening across 1.5M+ sanctioned, PEP and enforcement records — including 265k politically-exposed persons across 205 jurisdictions — every decision sealed into WORM cryptographic evidence with RFC 6962 audit proofs. Screen against a non-overridable sanctions floor, then show an examiner exactly what was checked, when, and why.

The engine

Five safeguards between a name and a decision

Screening you can defend is not one model — it is layered controls that each fail closed. Every one of them is enforced server-side and written to the evidence chain.

Non-overridable sanctions floor

Hard-sanctions matches surface at the platform floor regardless of any sensitivity slider. No UI control, key, or role can lower it — the floor is enforced in the engine, not the interface.

Independent best-of-three checker

Each result is re-derived by an independent scorer and reconciled across three passes. Disagreements are flagged, never silently dropped.

Maker-checker adjudication

Releasing or dismissing an asset-freeze match requires a distinct second approver. You cannot approve your own disposition — the platform refuses it.

Hash-chained evidence capsules

Every screening seals the full candidate set, scores and list snapshot into a capsule, hash-chained to the last and archived to WORM storage.

Metered pay-per-screen

Billing is counted from the same immutable decision log you are audited against. Start free with 200 screens a day; beyond that, subscribe to a plan or pay $1.50 per screening — no contract required either way.

WAF- & DDoS-hardened API

A rate-limited, WAF-fronted REST API with scoped ssk_ keys, signed webhooks and per-tenant isolation. Test and live keys never mix.

Developers

One call. A decision you can hand to an examiner.

A single REST endpoint returns a decision, the scored candidate set with a factor breakdown, and the id of the sealed evidence capsule.

  • Scoped keys. Mint ssk_test_ and ssk_live_ keys from the console, each limited to the scopes it needs.
  • Structured results. Every match carries its raw and adjusted score plus the exact factors that moved it.
  • Provable by id. The audit_id resolves to a WORM-sealed capsule with the full decision fingerprint.

Who screens with celmus

Built for anyone who has to prove they checked

Sanctions exposure is not only a banking problem. If a regulator, an auditor or a counterparty can ask who did you screen, against what, and when, celmus is built to answer it. The obligation stays yours — celmus is the infrastructure and the evidence behind the answer.

Money services & remittance

Screen sender and beneficiary on every transfer, at any amount, before funds move. Transaction screening with both parties, corridor context and a decision record per attempt — for FINTRAC, FinCEN and equivalent regimes.

Banks, lenders & credit unions

Customer due diligence at onboarding and re-screening thereafter, with structured PEP occupancy and relatives/close-associate links so enhanced due diligence is evidenced rather than assumed.

Fintechs & payment platforms

One REST call per entity, or batch your whole book. Sandbox keys in minutes, the same corpus as production, and per-tenant isolation if you screen on behalf of your own customers.

Crypto & digital assets

Sanctioned wallet addresses are carried as first-class entities alongside people and companies, so a VASP can screen a counterparty and a destination address through the same control.

Procurement & third-party risk

Debarment and exclusion coverage — including US federal exclusions and multilateral development-bank ineligibility — so supplier onboarding catches barred vendors, not only sanctioned ones.

Regulated professionals & marketplaces

Law, accountancy, real estate, gaming and platforms that onboard sellers: the same screening and the same examiner-ready evidence, without building a compliance stack to get it.

Vessels and aircraft are covered too, for trade finance and shipping exposure. Not sure whether your obligation fits? Start free — 200 screens a day, no card — or ask sales@celmus.com.

Pricing

Monthly subscriptions. PEP included. No seats.
