Agentic Services Protocol

An open protocol for end-to-end agent-to-service transactions — food delivery, ride-hailing, travel, and on-demand services. ASP covers the full transaction lifecycle from discovery to reviews, giving AI agents everything they need to interact with service marketplaces. For checkout and payment, ASP is compatible with UCP.
