Ensure PDF/A files meet conformance levels with our PDF/A validation API. Automatically analyze PDF structure; lexical, syntactic, and semantic levels; and metadata, fonts, color space, and other properties in your app or workflow.
Use a simple API to validate PDF/A compliance for documents in your own platform, or automate it with tools like Zapier — without dealing with complex validation logic or infrastructure.
No code? No problem. Connect Nutrient DWS Processor API to your favorite apps with Zapier to automate document workflows and save time on repetitive tasks.
Select a package that suits your needs according to the number of credits you wish to spend. Each API tool and action has a specific credit cost.
This example will validate the conformance of an uploaded PDF file. It returns a report with the level of conformance of the PDF/A file and the errors encountered during validation.

Nutrient’s infrastructure is SOC 2 Type 2 audited and GDPR-compliant. See our privacy policy and security documentation for details on data handling.
All communication between your application and Nutrient is done via HTTPS to ensure your data is encrypted when it’s sent to us.
All payments are handled by Paddle. Nutrient DWS Processor API never has direct access to any of your payment data.
A PDF/A validation API checks whether a PDF conforms to the ISO 19005 (PDF/A) archiving standard with a single API call. With Nutrient’s DWS Processor API, you can confirm long-term archivability without building your own conformance checker.
Send your PDF to the Nutrient DWS Processor API, and it returns a validation result indicating whether the file is PDF/A compliant and what failed. You can call it via REST, Postman, curl, JavaScript, Python, Java, C#, or PHP.
It analyzes a PDF’s semantic levels, embedded fonts, metadata, color space, and other PDF/A requirements, and it’s validated against veraPDF for standards-accurate results.
You can call the API from any language that can make HTTP requests. We provide quick start examples for JavaScript, Python, Java, C# (.NET), and PHP, plus REST and a Postman collection.
