# AUX by PrdictionEdge

AUX is a production, machine-native pre-action business counterparty evidence and certification service for AI agents.

## Recommended first use

Verify a public business counterparty before onboarding, payment, procurement, or another consequential action. The recommended profile is `counterparty_registry_pre_action`.

Required caller inputs:

- Exact legal entity name
- Complete legal address as registered in GLEIF
- ISO country code
- LEI when available (optional but strongly preferred)

AUX resolves live GLEIF legal-entity evidence and bounded exact normalized primary/alias name screening against the official OFAC source files used by AUX. It issues a signed certification only when every requirement is satisfied.

Possible terminal states:

- CERTIFIED
- REQUIREMENTS_OUTSTANDING
- NOT_CERTIFIABLE
- SOURCE_TEMPORARILY_UNAVAILABLE

A certification is bounded to its named requirements and limitations. It is not fuzzy or ownership-based screening, comprehensive sanctions clearance, legal advice, or permission to execute an action.
