API USAGE AGREEMENT
Effective as of 15th of September 2026
This Services Agreement is entered between Murf Inc., a Delaware corporation, with its principal place of business at 535 Mission Street, San Francisco, California 94105, United States of America (“Murf”), and a signatory party to duly executed Service Order Form referencing this Agreement. This Agreement contains the terms and conditions under which Murf Inc. provides its Services to the Customers. The provision of Services is contingent on the Customer's acceptance of the terms and conditions stated in this Agreement.

No conduct by Murf shall be deemed to constitute an acceptance of any terms put forward by the Customer unless such terms are explicitly accepted by signing the document containing such terms. For the avoidance of doubt, Murf does not accept any terms or provisions included by reference in any of the documents provided by the Customer, even if signed by Murf, unless Murf also signs such referenced documents.
