Watch the following 4-minute video to learn how to make POST requests to the Unstructured Partition Endpoint to process individual files: Open the related notebook that is shown in the preceding video. To make POST requests to the Unstructured Partition Endpoint, you will need: These environment variables:
  • UNSTRUCTURED_API_KEY - Your Unstructured API key value.
  • UNSTRUCTURED_API_URL - Your Unstructured API URL.
To get your API key, do the following:
  1. Sign in to your Unstructured account:
    • If you do not already have an Unstructured account, go to https://unstructured.io/contact and fill out the online form to indicate your interest.
    • If you already have an Unstructured account, sign in by using the URL of the sign in page that Unstructured provided to you when your Unstructured account was created. After you sign in, the Unstructured user interface (UI) then appears, and you can start using it right away. If you do not have this URL, contact Unstructured Sales at sales@unstructured.io.
  2. Get your Unstructured API key: a. In the Unstructured UI, click API Keys on the sidebar.
    b. Click Generate API Key.
    c. Follow the on-screen instructions to finish generating the key.
    d. Click the Copy icon next to your new key to add the key to your system’s clipboard. If you lose this key, simply return and click the Copy icon again.
The API URL was provided to you when your Unstructured account was created. If you do not have this URL, contact Unstructured Sales at sales@unstructured.io.
The default URL for the Unstructured Partition Endpoint is https://api.unstructuredapp.io/general/v0/general. However, this URL might not necessarily work for your account.
Let’s start with a simple example in which you use curl to send a local PDF file (*.pdf) to partition via the Unstructured Partition Endpoint. In this command, be sure to replace <path/to/file> with the path to your local PDF file. 
curl --request 'POST' \
"$UNSTRUCTURED_API_URL" \
--header 'accept: application/json' \
--header "unstructured-api-key: $UNSTRUCTURED_API_KEY" \
--header 'content-Type: multipart/form-data' \
--form 'content_type=string' \
--form 'strategy=vlm' \
--form 'vlm_model_provider=openai' \
--form 'vlm_model=gpt-4o' \
--form 'output_format=application/json' \
--form 'files=@<path/to/file>;type=application/pdf'
In the example above we’re representing the API endpoint with the environment variable UNSTRUCTURED_API_URL. Note, however, that you also need to authenticate yourself with your individual API Key, represented by the environment variable UNSTRUCTURED_API_KEY. Learn how to obtain an API URL and API key in the Unstructured Partition Endpoint guide.
