Anthropic Commercial Terms

This document establishes the commercial terms governing business and developer access to Anthropic's Claude API, excluding individual Claude.ai users who are covered under separate terms. The agreement specifies that customers retain ownership of content submitted to and received from the API, and that Anthropic will not use customer content for model training. The terms authorize Anthropic to suspend API access without liability upon determination of a security or compliance issue, require disputes to proceed through binding arbitration, and permit pricing modifications with thirty days' notice.

This document is Anthropic's Commercial Terms of Service (effective June 17, 2025), governing enterprise and developer access to the Anthropic API and related services; it establishes a binding agreement between Anthropic (Anthropic, PBC for non-EEA/UK/Switzerland customers; Anthropic Ireland, Limited for EEA/Switzerland/UK customers) and business customers, explicitly excluding consumer use. The agreement states that Customer retains all rights to Inputs and owns Outputs, that Anthropic assigns its interest in Outputs to Customer, and that Anthropic may not train models on Customer Content from the Services; it also states that Anthropic may suspend or terminate access without liability for service suspensions, and may update pricing rates effective 30 days after posting. Notably, the terms include a mutual IP indemnification structure with customer-favorable Output ownership assignment, a gross-up payment obligation for withholding taxes that places full tax burden on the Customer, and a mandatory bilateral arbitration clause with class action waiver applicable globally with region-specific arbitral forums; the breadth of the suspension and immediate termination rights without liability may warrant review under applicable law depending on jurisdiction. The document incorporates a Data Processing Addendum by reference for GDPR and international data privacy compliance, and the arbitration and governing law structure engages EU commercial arbitration frameworks for EEA customers and JAMS rules for others; the EU AI Act may be relevant depending on how customers deploy the Services, and applicable consumer protection and data residency requirements may constrain certain provisions for EEA-based business customers.

The agreement binds business users to binding arbitration and class action waivers for dispute resolution. Anthropic retains the right to suspend API access without financial liability if it determines a security or compliance issue exists. The terms permit Anthropic to modify pricing with thirty days' notice and require customers to remit applicable taxes; customers may submit an opt-out request to prohibit use of their company name and logo in Anthropic marketing materials.
