Capabilities

Tools 21

adverse_media

Roadmap probe, not yet served: adverse media screening with citations. Calling records the requirement and returns not-covered.

Discovered
charge_register

Roadmap probe, not yet served: outstanding charges and security for a UK company. Calling records the requirement.

Discovered
counterparty_evidence

In one call, assemble a Companies House candidate and profile with optional GLEIF and sanctions evidence. Supply a company number for a direct lookup, or a name and optional registered postcode for candidate resolution. Exact title matches are preferred; ambiguous or fuzzy-only matches are flagged for review. This is evidence assembly, not identity verification, a KYB decision, or sanctions clearance.

Discovered
cross_registry_resolve

Roadmap probe, not yet served: resolve a company across Companies House, GLEIF, OpenOwnership and sanctions lists into one entity record with per-assertion provenance. Calling records the ask and returns not-covered.

Discovered
entity_match

Compare two company references using supplied company-number/LEI equality and normalised name similarity. When one reference has a UK company number and the other only a name, optionally corroborates against Companies House. LEIs are compared as supplied, not validated against GLEIF by this tool. Returns an identifier-comparison verdict, review reasons and signal provenance. Names alone remain uncertain. Conflicting identifiers require review; confidence is null because no calibrated identity probability is available.

Discovered
eu_vat_check

Discovered
fca_register_check

Roadmap probe, not yet served: authorisation status of a firm or individual on the FCA register. Calling records the requirement.

Discovered
