This page describes what the document states, permits, or reserves. It does not constitute a legal determination about enforceability. Regulatory applicability may vary by jurisdiction. Methodology
This document sets the rules for developers who build applications using Perplexity AI's API. You own the outputs the API produces, but Perplexity AI owns usage data and can use it freely; you are responsible for verifying that outputs are accurate and for ensuring your users follow the Acceptable Use Policy. Perplexity AI can automatically charge your payment method and can suspend your application — including if it competes with Perplexity AI's own products.
The Perplexity AI API Terms of Service establishes the rights, obligations, and limitations governing developer access to the API Platform and Services. Perplexity AI grants customers a non-exclusive, non-sublicensable, and non-transferable license to use API Documentation solely for integration purposes, while retaining all right, title, and interest in Usage Data and reserving the right to use it for any lawful purpose without remuneration. Customer Content is expressly protected from use in training or fine-tuning generative AI models, including by third parties, and all Output rights are assigned to the customer. Customers bear responsibility for verifying Output accuracy, indemnifying Perplexity AI against third-party claims arising from their use of the Services, and ensuring all end-user conduct complies with the Acceptable Use Policy. Liability for indirect damages is mutually excluded, and Perplexity AI's aggregate liability is capped at fees paid in the 12 months preceding the triggering event.
As a developer using the API, you are responsible for checking the accuracy of all Outputs and may not rely on them for advice of any kind. You must ensure every end user of any application you build also complies with the Acceptable Use Policy, and you are financially responsible for third-party claims that arise from your use of the Services. Perplexity AI may suspend your application if it determines — on its own judgment — that it is unlawful, unethical, conflicts with API or Acceptable Use requirements, interferes with the Services, or competes with Perplexity AI. Perplexity AI cannot use your Customer Content to train or improve any generative AI models, including through third parties. If you handle Protected Health Information, you must execute a Business Associate Agreement with Perplexity AI before using the Services for that purpose.
