Independent counterparty evidence checks before autonomous transactions

AUX is a machine-native API that certifies whether an AI agent has enough independently verified evidence to proceed with a consequential action. It checks public business identity and sanctions sources, can validate signed private-source attestations, and returns signed certification receipts for downstream systems to evaluate.

Agenticness = how independently a tool can take action, scored across 9 dimensions. Scored independently by David Kooi, Skylark Creations — see full rubric → Last re-evaluated 13 September 2026.

About

What It Is

AUX is agent infrastructure for pre-action counterparty verification. It is aimed at developers, agent platforms, and organizations building autonomous systems that need an evidence-based control step before actions such as vendor payments or other consequential transactions.

What to Know

AUX is a verification and trust-control layer, not a general-purpose agent and not a payment-execution system. Its clearest value is separating an agent's own assertions from independently resolved or verified evidence, then attaching provenance and...

Key Features
Queries a machine-readable registry of live certification profiles and their bounded evidence requirements
Resolves GLEIF legal-entity status and registered-address evidence
Performs exact normalized primary-name and alias screening against official OFAC SDN and consolidated source files
Collects IANA RDAP and HTTPS domain-control evidence for counterparty domain identity
Verifies signed private-source attestations, including signature, freshness, subject binding, and transaction binding
Use Cases
Add a pre-payment counterparty check to an autonomous accounts-payable agent before it sends a vendor payment
Verify a supplier's legal-entity record and run a bounded OFAC name screen before an agent initiates a transaction
Require an agent to provide a signed invoice, ERP, or bank-destination attestation that AUX can independently validate
