PDF Support

Use AI models to send and analyze PDF documents.

OneRoute supports sending PDF documents to AI models for analysis, summarization, and question answering. This capability is available via the Chat Completions endpoint.

How It Works​

PDF documents are sent as part of the message content, either as base64-encoded data or as a URL. The AI model can then analyze the document and answer questions about its contents.

Chat Completions API​

Use the input_file content type to send a PDF. You can provide the PDF as base64-encoded data or as a URL.

Using a Base64-Encoded PDF​

curl https://gw.1route.ai/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_ONEROUTE_API_KEY" \
  -d '{
    "model": "anthropic/claude-sonnet-4-20250514",
    "messages": [
      {
        "role": "user",
        "content": [
          {
            "type": "text",
            "text": "Summarize this PDF"
          },
          {
            "type": "input_file",
            "filename": "document.pdf",
            "file_data": "data:application/pdf;base64,JVBERi0="
          }
        ]
      }
    ]
  }'

Using a PDF URL​

curl https://gw.1route.ai/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_ONEROUTE_API_KEY" \
  -d '{
    "model": "anthropic/claude-sonnet-4-20250514",
    "messages": [
      {

            "text": "Summarize this PDF"
          },
          {
            "type": "input_file",
            "filename": "document.pdf",
            "file_data": "https://example.com/document.pdf"
