Terms of Service

Last updated: April 17, 2026

1. Service description

PDF Accessibility Tagger is an API service that accepts native PDFs and returns versions with semantic tagging plus review-oriented workflow metadata intended to support accessibility remediation workflows.

The service uses an asynchronous staged-upload workflow: request an upload slot, upload the PDF to temporary staged storage, finalize the job, and retrieve the result when processing completes.

The service is an automation tool. It does not guarantee that output documents meet any legal or technical accessibility standard without further review.

2. Geographic scope

The service is offered solely to users located in the United States. By using the service, you represent that you are accessing and using it from within the United States, and you agree not to access or use the service from any jurisdiction outside the United States. We make no representation that the service is appropriate or available for use in any other jurisdiction. Users who access the service from outside the United States do so on their own initiative and are responsible for compliance with applicable local laws.

3. Acceptable use

You must be at least 18 years old, or the age of legal majority in your jurisdiction if that is higher, to use the service. You may use the service only for lawful purposes and only for documents you have the right to upload and process.

You agree not to:

  • upload malicious or unlawful content
  • attempt to interfere with service availability or security
  • use the service to process documents in violation of privacy, confidentiality, or intellectual-property rights
  • abuse the service through excessive, automated, or hostile request patterns beyond allowed limits

4. Customer responsibilities

You are responsible for:

  • ensuring you have rights to the submitted documents
  • reviewing outputs before relying on them for accessibility, compliance, legal, or publication purposes
  • not treating the service as a legal certification authority
  • retrieving results within the retention window (results expire after 3 days)

5. No compliance guarantee

The service may improve document structure and machine readability, but does not guarantee:

  • PDF/UA compliance
  • WCAG compliance
  • legal sufficiency for any jurisdiction
  • correction of every accessibility issue in every PDF

Human review and remediation may still be required. This is especially true for figures or other non-text elements when the source PDF does not provide credible descriptive text or nearby caption context.

6. Async processing

When using the async API:

  • upload-slot allocation does not guarantee processing success
  • uploading a file to the presigned URL does not by itself start processing; the client must finalize the staged upload
  • documents are staged temporarily in encrypted cloud storage
  • all staged artifacts are automatically deleted after a bounded retention period of 3 days
  • results must be retrieved before the retention period expires
  • failed jobs include error details in the job status response

7. Unsupported inputs

The service may reject or fail to process documents including but not limited to:

  • scanned or image-only PDFs
  • malformed or unreadable PDFs
  • encrypted or password-protected PDFs
  • oversized files (exceeding the published size limit)
  • documents with no detectable structural elements

8. Availability

The service may change, be rate-limited, or be unavailable from time to time. The service is provided on an "as available" basis and no specific uptime or availability level is guaranteed. Rate limits, quotas, and processing capacity are governed by the subscription plan purchased through the marketplace listing.

9. Data handling

Data handling is described separately in the Privacy Policy and Data Handling documents, both of which are incorporated into these terms by reference.

The product posture is ephemeral document processing, not persistent document storage. Temporary staging required by the async processing path is strictly bounded by infrastructure lifecycle rules.

The service also returns workflow metadata and review guidance as part of the product contract. That metadata is intended to help customers understand processing outcome and where additional review may still be appropriate.

10. Suspension and termination

Access may be suspended or terminated for abuse, misuse, unlawful activity, nonpayment, or behavior that threatens service stability or other users.

11. Disclaimer of warranties and limitation of liability

The service is provided "as is" and "as available" without warranties of any kind, whether express or implied, including without limitation any warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, or that the service will be uninterrupted or error-free.

To the maximum extent permitted by applicable law, in no event shall the service provider be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, or goodwill arising out of or in connection with the use of or inability to use the service, even if advised of the possibility of such damages.

The total aggregate liability of the service provider arising out of or relating to these terms or the service shall not exceed the greater of (a) fifty U.S. dollars ($50) or (b) the amounts received by the service provider for the customer's use of the service during the three (3) months immediately preceding the event giving rise to the claim.

Some jurisdictions do not allow the exclusion or limitation of certain warranties or damages, so some of the above limitations may not apply.

12. Governing law and venue

These terms are governed by the laws of the State of California and applicable federal laws of the United States, without regard to conflict-of-laws principles.

Any legal action or proceeding arising out of or relating to these terms or your use of the service shall be brought exclusively in a state or federal court of competent jurisdiction located in the State of California, and you consent to the personal jurisdiction of such courts.

13. Changes

These terms may be updated as the product evolves. Material changes will be reflected by updating the "Last updated" date at the top of this document. Continued use of the service after a change constitutes acceptance of the updated terms.

14. Contact

For support, billing, or legal inquiries, use the contact channels listed on the service's RapidAPI marketplace listing.
