}Retrieve a file
Planned contract — unavailable in test and live modes. This operation is a protocol reference, not a callable endpoint. Start with the working sandbox quickstart.
Returns a file. After a JSON upload, read it until status is ready, then send its ID in
a check’s inputs or a generation’s artifact.
Restricted keys need files:write.
