SNAP Terms of Service

CHAPTER 1 GENERAL PROVISIONS

Article 1 (Purpose)

The purpose of these Terms is to set forth the rights, obligations and responsibilities of KustodyFi Co., Ltd. (the "Company") and its users, as well as other necessary matters, in connection with the use of "SNAP" (the "Service"), through which the Company provides access to financial institution information (including traditional foreign exchange (FX) quotes, financial product information and interest rate information; "Financial Institution Information") received from domestic and overseas financial institutions with which the Company has entered into formal agreements, additionally provides analytical content produced by the Company in accordance with its proprietary models and published methodologies, and delivers the foregoing in connection with AI services via API/MCP (Model Context Protocol) and similar means.

The purchase of paid services, free trials, recurring payments, pricing, taxes, withdrawal of subscription, termination and refunds are additionally governed by the Paid Service Terms of Use. In the event of a conflict between these Terms and the Paid Service Terms of Use, the Paid Service Terms of Use shall prevail with respect to the purchase, payment and refund of paid services. However, where an individual order form or a separate written agreement expressly conflicts with these Terms or the Paid Service Terms of Use, such order form or separate written agreement shall prevail.

Article 2 (Definitions)

The terms used in these Terms are defined as follows:

It constitutes the basic content of the Service.

2."Analytical Content" means the analytical outputs (including, without limitation, comparisons by maturity, annualized conversions, curve construction and interpolation, and historical statistical analysis) that the Company generates on the basis of Financial Institution Information and other inputs in accordance with its proprietary models and published methodologies, and provides as a value-added feature of the Service. Analytical Content is limited to technical and computational analysis and does not include market outlooks, investment or trading recommendations, or judgments as to the timing or direction of any transaction.

3."User" means an individual or legal entity that has entered into a service agreement with the Company under these Terms and uses the Service provided by the Company. "Member" means a person who has completed member registration by providing personal information to the Service and who uses the Service under an account (including an API Key) issued by the Company.

4."API" means the application programming interface provided by the Company to enable a User to access the Service programmatically through the User’s own application, system or AI agent.

5."AI Platform" means a third-party conversational artificial intelligence service, or an agent framework that enables a User to connect to the Service through a protocol such as MCP.

6."Third-Party Login Provider" means Google, and any other credential provider that the Company may additionally support in the future, which the Company supports so that a User may sign up for and authenticate to the Service via OAuth instead of creating authentication credentials directly with the Company.
