Implement programmatic FedRAMP authorization status lookup using the marketplace data export

Verified steps

1. Access the FedRAMP Marketplace at marketplace.fedramp.gov; for programmatic use, use the JSON data export endpoint or download the marketplace data file from the GSA/marketplace-fedramp-gov-data GitHub repository.
2. Parse the JSON export to build a lookup indexed by CSO (Cloud Service Offering) name and provider name; key fields include authorization_status (Authorized, In Process, Ready), the authorizing agency, and the impact level (Low, Moderate, High).
3. Automate periodic refresh of the data (recommended: daily or weekly) since FedRAMP authorization statuses change as new services are authorized or as existing authorizations are revoked or expire.
4. Integrate the lookup into your vendor procurement or third-party risk management workflow: before issuing an ATO for a cloud service, confirm the service appears with FedRAMP Authorized status at the required impact level.
5. Cross-reference the marketplace status with the specific agency ATO requirement: FedRAMP authorization is necessary but not sufficient — each agency must still issue its own ATO based on the package on file.
6. Alert on any vendor in your active portfolio whose marketplace status changes from Authorized to In Process or is removed entirely, as this may indicate a lapsed authorization requiring immediate risk management action.
