To query hosted RIM files, run the following:
$ curl -X GET "https://rim.attestation.nvidia.com/v1/rim/ids" -H 'accept: application/json' | jq | grep <ASIC_Name>
For example:
$ curl -X GET "https://rim.attestation.nvidia.com/v1/rim/ids" -H 'accept: application/json' | jq | grep CX7

Each of these IDs includes a RIM encoded as a base64 string. You can retrieve the CoRIM file using the following commands (with curl, jq, and base64):
curl -s 'https://rim.attestation.nvidia.com/v1/rim/NV_NIC_FIRMWARE_<ASIC_Name>_<version>_<SKU>' | jq -r '.rim' | base
For example:
curl -s 'https://rim.attestation.nvidia.com/v1/rim/NV_NIC_FIRMWARE_CX7_28.44.1036_MCX755106AS-HEA' | jq -r '.rim' | base
