CUSTOMER AGREES TO THESE TERMS OF SERVICE BY (A) CLICKING TO ACCEPT OR AGREE WHERE SUCH OPTION IS MADE AVAILABLE TO CUSTOMER, OR (B) ACTUALLY USING OR ACCESSING THE SERVICES (THE “EFFECTIVE DATE”).\nThese Terms of Service constitute an agreement (the “Agreement”) by and between PathCourse Health LLC (“PathCourse”, “Company”, or “we”) and the corporation, LLC, partnership, sole proprietorship, nonprofit, other entity, or individual (“Customer” or “you”) agreeing to this Agreement. Company and Customer may be referred to individually as a “Party” and collectively as “Parties.” \nThis Agreement is effective as of the Effective Date. Customer’s use of and Company’s provision of the Services (as defined below in Section 1) are governed by this Agreement.\nDEFINITIONS. The following capitalized terms will have the following meanings whenever used in this Agreement:\n“Affiliate” means any entity that directly or indirectly controls, is controlled by, or is under common control with the subject entity. “Control,” for purposes of this definition, means the power to direct or cause the direction of the management and policies of an entity, whether through ownership of voting securities, by contract or otherwise.\n“Feedback” means any suggestion, enhancement request, recommendation, correction or other feedback provided by Customer or Users.\n“Customer Data” means all information, documents, images, files or materials uploaded, created, modified, or stored in the Services by Customer or Customer’s Users.\n“Services” means the PathCourse platform and offerings, including, without limitation and as applicable, the offerings made available through the Site.\n“Site” means all websites, applications, and other online platforms owned, operated, or managed by Company. This includes, but is not limited to, websites, any subdomains thereof, all mobile applications published by Company, and any other digital services or platforms where Company provides content, products, or services.\n“User” means any individual who uses the Services on Customer’s behalf or through Customer’s account or passwords, whether authorized or not, or any individual who Customer grants access or use to the Services under the rights granted to Customer pursuant to this Agreement.\nNATURE OF THE SERVICES; MACHINE-TO-MACHINE PROTOCOL.\nThe Services are an autonomous, machine-to-machine protocol accessed programmatically by software agents over HTTPS using the x402 payment protocol. There are no user accounts, registrations, log-ins, passwords, or human sign-in of any kind, and Company does not collect identity information (no KYC). Authorization and payment occur in a single step: a request is authorized by, and payable through, a signed USDC payment authorization on the Base network (chain_id 8453), and settlement transfers funds directly from the requester to Company's treasury without Company taking custody of any balance. As used throughout this Agreement: (a) “Customer” and “User” mean the requesting software agent together with the person or entity on whose behalf it operates, who are jointly and severally responsible for all acts and omissions of the agent; (b) a party accepts and becomes bound by this Agreement by submitting a paid x402 request to, or otherwise accessing, the Services (no click-to-accept or sign-up is required); (c) references to accounts, account access credentials, passwords, registration, a browser, or email contact points refer to the equivalent protocol mechanisms, including the requester's wallet and signing material, or, where no equivalent exists, do not apply; and (d) any requirement to send notice to an email or account contact point is satisfied, where the requester provides none, by Company posting the notice at the location where these Terms are published or by returning it in a protocol response. In the event of any conflict between this Section and any other provision of this Agreement, this Section controls.\nACCESS AND USE OF THE SERVICES\nProvision of Access.
