Get a file

Prerequisites

Endpoint and authentication are configured. See Overview and authentication.

Endpoint

GET /files/{file_id}

Returns file metadata (filename, size_bytes, mime_type, created_at, status); content is not included. The scope field is returned only on session-sandbox internal copies.

Status values

status reports the safety scan result. Values: available (passed; mountable into sessions), checking (in progress), rejected (content failed review), type_rejected (file type unsupported). Only files with status available can be mounted into a session or referenced as message content.

file = client.files.retrieve("file_xxx")
print(file.filename, file.size_bytes, file.mime_type)

AgentStudioFile f = client.files().retrieve("file_xxx");
System.out.println(f.getFilename() + " " + f.getSizeBytes());
