Query data assets in batches¶

Batch query of generated data assets by original file ID; unprocessed files will not appear in the results.

POST https://moi.matrixorigin.cn/newmoi/catalog/data-assets/batch-get

Preparation before calling¶

First query the file list to obtain the file ID. Prepare a list of personal access tokens, target workspace IDs, and file IDs that have access to the target workspace.

The example below uses:

$AI_STUDIO_API_KEY: The actual personal access token, passed through the X-API-Key Header.
$WORKSPACE_ID: Target workspace ID, passed through X-Workspace-ID Header.
$FILE_ID: Original file ID.

Empty file IDs in requests are ignored, and duplicate IDs are only processed as the first occurrence.

Request example¶

curl -X POST "https://moi.matrixorigin.cn/newmoi/catalog/data-assets/batch-get" \
  -H "X-API-Key: $AI_STUDIO_API_KEY" \
  -H "X-Workspace-ID: $WORKSPACE_ID" \
  -H "Content-Type: application/json" \
  -d '{
    "raw_file_ids": ["'"$FILE_ID"'"]
  }'

Request body¶

Parameter	Type	Required	Description
`raw_file_ids`	string[]	Yes	A list of original file IDs to query.

[] after a type means an array. For example, string[] is an array of strings.
