Perplexity can change these terms at any time, and continuing to use the API after being notified counts as agreeing to the new terms.
This analysis describes what Perplexity AI's agreement states, permits, or reserves. It does not constitute a legal determination about enforceability. Regulatory applicability and practical outcomes may vary by jurisdiction, enforcement context, and individual circumstances. Read our methodology
The continued-use acceptance mechanism means developers who do not actively review and respond to term changes may find themselves bound by materially different obligations without having explicitly consented to them.
Developers and their applications may become subject to new restrictions, obligations, or data use terms following a modification notice, and continued API use without review constitutes acceptance under this clause.

"Perplexity reserves the right to modify these Terms at any time. We will notify you of material changes by posting the updated Terms on our website or by sending you an email. Your continued use of the API following such notice constitutes your acceptance of the modified Terms.— Excerpt from Perplexity AI's Perplexity API Terms of Service
REGULATORY LANDSCAPE: Continued-use acceptance clauses are common but have faced scrutiny in consumer protection contexts. For B2B agreements, they are generally more enforceable, though some jurisdictions require affirmative re-consent for material changes, particularly where personal data processing is involved. Under GDPR, changes to data processing terms may require re-evaluation of lawful bases or updated DPAs. The FTC and state AGs have challenged inadequate change notification practices in consumer contexts. GOVERNANCE EXPOSURE: Medium. The notification mechanism described, website posting or email, is standard but the reliance on continued use as consent is operationally risky for organizations that do not have automated processes for reviewing incoming policy change notifications. Material changes to data use or liability terms could take effect without active review. JURISDICTION FLAGS: EU/EEA developers should assess whether continued-use acceptance is sufficient under applicable consumer or commercial law for material changes. California contract law may scrutinize whether adequate notice was provided for significant modifications. CONTRACT AND VENDOR IMPLICATIONS: Vendor management processes should include a workflow for reviewing and documenting responses to Perplexity term change notifications. Where changes are material, legal teams should assess whether the new terms require renegotiation, supplemental DPA execution, or cessation of certain use cases. COMPLIANCE CONSIDERATIONS: Organizations should implement processes to track and review API provider policy changes. Subscription to Perplexity's policy change notifications should be confirmed. Internal workflows should define a decision timeline for assessing and responding to material term changes before the continued-use acceptance window closes.
