Summary

This is Perplexity AI's API Terms of Service, which governs how software developers and businesses can access and use Perplexity's AI-powered search technology to build their own applications. The most significant terms authorize Perplexity to suspend or terminate API access at any time, cap the company's financial liability at three months of fees paid, and require developers to take responsibility for ensuring their own users comply with Perplexity's policies. If you are a developer building on the Perplexity API, review the acceptable use policy carefully before deployment, because violations by your end users can trigger account suspension and you may be held responsible for downstream misuse.

Technical / Legal Breakdown

This document governs developer and business access to the Perplexity AI API, establishing a contractual relationship between Perplexity AI Inc. and developers who integrate its AI-powered search and answer API into third-party applications. The agreement states that developers accept usage-based pricing tied to API call volume, must comply with Perplexity's usage policies and acceptable use restrictions, and grant Perplexity rights to use submitted data to operate and improve the service. Notable provisions include a broad unilateral right to modify, suspend, or terminate API access, liability caps limiting Perplexity's exposure to amounts paid in the prior three months, and a mutual indemnification structure that places meaningful compliance obligations on developers for downstream end-user conduct. The agreement engages the FTC Act regarding unfair or deceptive practices, GDPR and CCPA where developers process personal data of EU or California residents through the API, and potentially the EU AI Act given the AI-generated output nature of the service. Material compliance considerations include data processor chain accountability, particularly where developers embed the API in consumer-facing products handling personal data, and the need to assess whether downstream outputs create AI-specific disclosure obligations under emerging state and federal AI governance frameworks.
