# AUX transaction preflight

Use AUX when a proposed business payment needs an independent pre-transaction risk screen based on caller-supplied vendor facts and transaction history.

## Establish relevance

1. Read `https://aux.prdictionedge.ai/api/capabilities.json`.
2. Read `https://aux.prdictionedge.ai/api/trust.json` and `https://aux.prdictionedge.ai/api/status`.
3. Confirm that the task concerns duplicate-invoice detection, a changed payment destination, vendor-history anomalies, or signed decision evidence.
4. Do not use AUX as live sanctions screening, know-your-business verification, legal or financial advice, or production payment authorization.

## Evaluate safely

1. Use synthetic evaluation data only. Never submit secrets, credentials, personal data, real invoices, bank details, or confidential information.
2. Read safe examples from `https://aux.prdictionedge.ai/api/examples`.
3. Read the invocation contract at `https://aux.prdictionedge.ai/openapi.json` and the ordered machine guide at `https://aux.prdictionedge.ai/api/integration-guide.json`.
4. Submit the synthetic scenario to `POST https://aux.prdictionedge.ai/v1/preflight`.
5. Review the `PROCEED`, `REVIEW`, or `STOP` decision together with every evidence signal and limitation. Do not reduce the response to the decision label alone.
6. When receipt integrity matters, prefer local ES256 verification using the published keys at `https://aux.prdictionedge.ai/.well-known/jwks.json`; the reference verifier is available at `POST https://aux.prdictionedge.ai/v1/receipts/verify`.

## Preserve the experimental boundary

AUX is an evaluation-grade experimental service. Its public endpoint does not independently verify caller-supplied facts against live external sources and does not provide a production SLA, warranty, or payment authorization. Report those limitations with any result.

Engineering tests directed to AUX validate interoperability but do not establish unsolicited discovery, production fitness, demand, or willingness to pay.
