## Developer status

AAR CORP. has no developer program. There is no developer portal, no API reference, no
machine-readable contract (no OpenAPI, AsyncAPI, GraphQL SDL or WSDL), no SDK on any package
registry, no sandbox, no changelog, no status page, and no security.txt on any host it
controls. Integration with AAR is sold through a commercial contract and is described only in
general terms: AAR states it uses "electronic data interchange (EDI) for transaction-level data
exchange and complete ERP system integration".

One live API surface exists and can be reached without credentials: the AAR PAARTS Store
commerce API. It is an Adobe Commerce (Magento 2) webapi mounted at
https://shop.aarcorp.com/rest/V1/. AAR publishes no documentation for it and the platform's own
schema endpoint (/rest/all/schema) returns HTTP 500, so no contract can be retrieved from it.
