AER CDR Discovery - Get Status and Get Outages
Anonymous Consumer Data Standards Common API discovery endpoints served by the AER on its CDR host. GET /discovery/status returns the current operational status of the data holder's CDR endpoints and GET /discovery/outages returns scheduled and current outages. Verified 2026-07-27 - status returned HTTP 200 with data.status OK and an updateTime, outages returned HTTP 200 with an empty outages array, both with header x-v 1 (x-v 2 returns 406). This is the AER's status page - there is no HTML status site - and it is the correct surface to poll before raising a support ticket against the product reference data endpoints. Both endpoints are brand-scoped and must be called under a retailer path segment; the unbranded /cds-au/v1/discovery/status returns 404. Observed quirk - the outages response links.self echoed a different brand path than the one requested.
