Getting started with DWS Accessibility API

Use the steps below to run your first PDF accessibility auto-tagging request.

Prerequisites

Complete the prerequisites below before sending requests:

1. Create an account in the DWS dashboard(opens in a new tab).
2. Open the DWS Accessibility dashboard(opens in a new tab).
3. Create or select an application, and then generate an API key.

Auto-tag a local PDF

Use a multipart upload request when the source PDF is local:

curl -X POST "https://api.nutrient.io/accessibility/autotag" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "file=@document.pdf" \
  --fail \
  -o tagged.pdf

Auto-tag from a URL

Use JSON input when the source PDF is already hosted remotely:

curl -X POST "https://api.nutrient.io/accessibility/autotag" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "file": { "url": "https://example.com/source.pdf" }
  }' \
  --fail \
  -o tagged.pdf

Notes and limits

Keep the limits below in mind when planning integration:

• Input must be a PDF document.
• Maximum upload size is 150 MiB per file.
• Auto-tagging reduces manual remediation work, but you should still review output quality in your QA process.

Next steps

• Refer to the auto-tagging guide for implementation details.
• Refer to the accessibility best practices guide before production rollout.
• Refer to the pricing guide to size monthly quotas.
