You can use any language to make this CURL call. (Python, PHP, Java, JavaScript...) Need help ?

curl --location --request POST 'https://mxprocess.com/api/login_check' \
                                        --header 'Content-Type: application/json' \
                                        --data-raw '{"username":"YOUR_LOGIN","password":"YOUR_PASSWORD"}'

If your credentials are correct, our server will provide you with a token as a response :

{"token": "YOUR_TOKEN","refresh_token": "YOUR_REFRESH_TOKEN"}

YOUR_TOKEN is valid for one hour, its duration can be extended using YOUR_REFRESH_TOKEN

Use the token to start the process

API Documentation, MetadataCleaner

Downloading results: when it is present in an API response, actionResultsDownloadURLs contains the authenticated URLs for downloading each generated result file.

Asynchronous API: clean file metadata

Submit exactly one image, PDF, audio or video file up to 50 MiB. The original is never modified. The service removes common metadata recognised by ExifTool from a copy and preserves orientation and colour-profile tags when supported. This is not a guarantee of complete anonymisation.

Endpoint: POST https://mxprocess.com/api/files/start-process
Authentication: Bearer JWT
Cost: 3 tokens, charged after success.

Start a cleanup

curl --location --request POST 'https://mxprocess.com/api/files/start-process' \
--header 'Authorization: Bearer YOUR_TOKEN' \
--form 'actionName=MetadataCleaner' \
--form 'file=@/path/to/file.jpg' \
--form 'parameters=[]' \
--form 'async=true'

Save the returned id and poll /api/actions/get-action-infos/{id} with the same JWT. When accomplished is true, actionResults contains both the cleaned file (cleaned-<original>) and <original>.metadata-report.json. Download each result through its authenticated URL.

Initial response

{"id":123,"action":{"actionName":"MetadataCleaner","slug":"clean-file-metadata-online"},"accomplished":false,"actionResults":[],"trackingUrl":"https://mxprocess.com/api/actions/get-action-infos/123"}

}

If the file has no writable metadata (for example plain text), the copied file is returned unchanged and metadataFoundBefore is false. Invalid cardinality, an inaccessible file or a file over 50 MiB is rejected before processing.

The API sends a JSON response to confirm that the process is finished. Download the generated files with the authenticated URLs in actionResultsDownloadURLs.
