Service Level Agreement

Last updated: December 4, 2025

  1. Overview
    The Service Level Agreement (“SLA”) outlines the support commitments that LUMX will offer to its CLIENT regarding the reliability of its own API, issue resolution, and transparency in communication. It does not cover response times or service levels of its contracted suppliers and partners.

  2. SLA Scope
    This SLA applies to the CLIENT integrated with the LUMX Platform for transaction processing, liquidity management, and financial settlements. It defines issue severity levels, response times, and escalation paths.

    2.1 API Availability Guarantee. LUMX ensures that the API made available through the LUMX Platform will have a minimum availability level of 99% (ninety-nine percent), calculated on a monthly basis. This availability level refers to the time during which the API is operational and accessible for use by the CLIENT, excluding interruptions due to scheduled maintenance, force majeure events, or failures beyond LUMX’s reasonable control.
