This operation has no input parameters.
A JSON object containing a containers array with each container's name and lastModified timestamp, along with the total count of containers.
Create Container
Creates a new blob container. Use this to organize files into logical groups, create isolated storage spaces for different projects or customers, or set up a new storage location for workflow outputs.

Deletes a blob container and all its contents. Use this for cleanup operations, removing test containers, or archiving completed projects. This permanently deletes all blobs in the container.
| Parameter | Description | Type | Required/Optional |
|---|---|---|---|
| Container Name | Name of the container to delete. | string | Required. |
A JSON object containing the deletion status and the container name of the deleted container.
List Blobs
Lists blobs in a container with optional prefix filtering and pagination support. Use this to discover what files exist before processing, iterate through large collections, or filter files by folder-like prefixes (e.g., reports/2024/).

| Continuation Token | Continuation token for pagination, retrieved from a previous response. | string | Optional. |
A JSON object containing the container name, a blobs array with each blob's name, size, lastModified timestamp, blobType, and contentType, along with the total count, a hasMore flag indicating if more results exist, and a continuationToken for pagination.

| Overwrite | Whether to overwrite the blob if it already exists. | boolean | Optional. |
A JSON object containing the upload status, blob name, container name, file size, contentType, url of the uploaded blob, any metadata, and the sourceUrl if uploaded from a URL.
Upload Blob From URL
Uploads a blob by fetching content from an external URL, without requiring local download first. Use this to import files from external sources such as images, mirrored content, or web resources. Supports HTTP/HTTPS only.
| Parameter | Description | Type | Required/Optional |
|---|---|---|---|
| Container Name | Name of the container to upload the blob to. | string | Required. |

| Max Size MB | Maximum allowed file size in MB. Defaults to 100 MB, with a maximum of 500 MB. | integer | Optional. |
A JSON object containing the upload status, blob name, container name, file size, contentType, url of the uploaded blob, any metadata, and the sourceUrl used to fetch the content.
Get Blob Properties
Retrieves properties and metadata of a specific blob. Use this to check if a file exists, retrieve its size or type before downloading, or read custom metadata without downloading the full content.
| Parameter | Description | Type | Required/Optional |
|---|---|---|---|
| Container Name | Name of the container containing the blob to retrieve. | string | Required. |
| Blob Name | Name or path of the blob. For example, folder/file.pdf. |
string | Required. |
A JSON object containing the exists flag, blob name, container name, size, contentType, lastModified timestamp,eTag, blobType, and url of the blob.
Download Blob

| Parameter | Description | Type | Required/Optional |
|---|---|---|---|
| Container Name | Name of the container containing the blob to download. | string | Required. |
| Blob Name | Name or path of the blob. For example, folder/file.pdf. |
string | Required. |
A JSON object containing the blob name, container name, size, and the base64 encoded content of the downloaded blob.
Delete Blob
