# Machine Commerce > One commerce API for every agent. Machine Commerce is an API, MCP server, and SDK that gives AI agents a single unified interface to discover, quote, authorize, execute, and receive receipts for transactions across products, APIs, services, and agent-native merchants. ## What it does AI agents can use Machine Commerce to: - **Search** — find products, APIs, services, and agent-native merchants - **Quote** — get price, availability, payment options, and execution path - **Authorize** — apply spend limits, approvals, and payment policies - **Execute** — complete checkout, pay for APIs, or invoke services - **Receipt** — return proof, status, logs, and results One schema in. One receipt out. ## Why it exists Commerce is fragmented. Every agent developer today would otherwise need to integrate Shopify, UCP, x402, MPP, ERC-8004, payment handlers, custom MCP servers, and APIs separately. Machine Commerce provides one unified interface for all of it. ## Protocols supported Works across: Shopify / UCP, x402, MPP, ERC-8004, MCP, custom APIs. ## Trust and control - Spend limits and daily caps - Approval rules and payment constraints - Immutable receipts and audit logs - Quality ranking and merchant reliability scoring ## Status Early access. Not yet publicly available. Built for developer teams building agents that do real commercial work. ## Contact - Founder: David Tilser - Book a call: https://calendar.app.google/qAppqhTeeNxZLqw18 - Telegram: https://t.me/davidtilser - X: https://x.com/davidtilser - LinkedIn: https://www.linkedin.com/in/davidtilser/ ## Links - Homepage: https://machinecommerce.dev/
