# AUX

> Independent, evidence-backed pre-transaction screening for autonomous agents. Available now for free, no-account evaluation with machine-verifiable signed receipts.

This file follows the llms.txt community proposal. It is not an adopted web standard. Authoritative machine discovery is available through the RFC 9727 API catalog and OpenAPI description.

## Safety

The public endpoint is an evaluation service without live external verification or a production SLA. Use synthetic test data only; do not submit secrets, credentials, personal data, real invoices, bank details, or confidential information.
