The record

Purpose: The cloud API automatically tags PDF files and validates accessibility conformance.
Output: The workflow accepts a PDF and returns a tagged PDF with PDF/UA metadata.
Tagging features: It detects H1–H6 headings, ordered and unordered lists, table rows and cells, reading order, annotations, and decorative artifacts.
Standards: The API targets PDF/UA-1 (ISO 14289-1) conformance.
Benchmark: Nutrient reports 96.5% PDF/UA conformance across a 3,157-file validation corpus.
Security: Nutrient says its infrastructure is SOC 2 Type 2 audited and GDPR-compliant, and API requests must use HTTPS.
Payment security: Payments are processed by Paddle, and Nutrient says it does not access payment data.
Compliance caveat: Nutrient says auto-tagging reduces manual work but does not guarantee full accessibility compliance, and recommends validating outputs in QA, especially for legally sensitive or high-stakes documents.
Quota behavior: Monthly page and validation quotas do not roll over, and requests in a quota category are blocked after that quota is reached unless the customer moves to a larger plan or uses pay-as-you-go.
Validation-only: A validation-only plan is not currently offered; all plans include both auto-tagged pages and validation quotas.
Support: All plans include documentation and developer support, with additional support options depending on plan.
Company: Nutrient says it serves thousands of organizations in more than 80 countries, including Fortune 500 companies and governments.
