Summary

This is the Perplexity AI API Terms of Service, governing developer and business use of Perplexity's API to build applications powered by its AI search and answer capabilities. The agreement grants Perplexity a license to use content submitted through the API, including prompts and outputs, for purposes including service improvement, and caps Perplexity's liability to developers at amounts paid in the prior twelve months regardless of the nature of the loss. Perplexity reserves the right to suspend or terminate API access at its discretion, which creates operational dependency risk for applications built on the service.

Technical / Legal Breakdown

This document governs developer access to and use of the Perplexity AI API, establishing the contractual basis under which developers may integrate Perplexity's AI-powered search and answer engine capabilities into third-party applications. The agreement states that developers must comply with Perplexity's usage policies and acceptable use requirements, that Perplexity retains ownership of the API and underlying models, and that developers grant Perplexity a license to use inputs and outputs submitted through the API for service improvement and safety purposes. The terms authorize Perplexity to suspend or terminate API access at its discretion, assert broad indemnification obligations on developers, and cap Perplexity's liability at amounts paid in the prior twelve months, which is a structurally significant limitation for enterprise deployments building revenue-generating products on the API. The document engages GDPR and CCPA where developers process personal data of EU or California residents through the API, and developers acting as data controllers or processors under those frameworks may have obligations not fully addressed by the agreement's terms. Material compliance considerations include data processing agreement requirements for EU-based deployments, the scope of the license granted over developer inputs and model outputs, and the absence of explicit SLA or uptime commitments relevant to operational dependency assessments.

What changed Perplexity AI modified one sentence in their API Terms of Service on May 27, 2026, changing a cross-reference from Section 8 to Section 9 in the liability limitations clause. The change corrects which section governs indemnification obligations that are excluded from the liability cap. This appears to be a technical correction to internal document structure rather than a substantive change to consumer rights or obligations.
Why this matters This change is a technical correction to an internal cross-reference in the liability limitations clause and does not alter the substantive rights, obligations, or protections available to API users. The underlying liability limitation remains unchanged.

What changed On May 18, 2026, Perplexity AI updated a single word in the footer navigation of its API Terms of Service document.

Why this matters This change has no impact on the actual terms of service or how Perplexity's API operates.

Recent Provision Changes May 27, 2026

Added (1)
Governing Law and Dispute Resolution Low

Establishes exclusive jurisdiction in California courts and California law governance, potentially favoring Perplexity and limiting developers' ability to litigate in their home jurisdictions.

Removed (2)
Developer Responsibility for End-User Conduct

Removal eliminates developer liability for downstream end-user violations, substantially reducing developer risk exposure.

Modification of Terms

Removal of unilateral modification rights language suggests either removal of this power or relocation to another section, materially affecting Perplexity's flexibility to update terms unilaterally.

Modified (6)
Input and Output License to Perplexity

Scope expanded from 'analyze' to 'distribute' outputs, and purposes broadened from 'maintaining and improving the Service' to 'developing the Services,' giving Perplexity broader rights to redistribute user-generated content.

Liability Cap

Liability cap calculation changed from 'greater of $100 or 3-month fees' to 12-month fees only, removing the minimum $100 floor and significantly increasing Perplexity's potential exposure for larger customers.

Unilateral Termination and Suspension Right

Removed the mandatory data destruction obligation upon termination, reducing post-termination compliance burden on developers.

Developer Indemnification Obligation

Added 'affiliates' to protected parties and changed 'infringement of any intellectual property or other rights of any person or entity' to narrower 'violation of any third-party rights,' reducing indemnification scope slightly.

Acceptable Use Restrictions

Removed competitive use restriction and high-risk application safeguard requirement, but added explicit prohibitions on deceptive practices, misinformation, and infrastructure abuse, shifting focus from competitive harm to content quality and infrastructure protection.
