Agentic Commerce Protocol | Rakesh Gohel

Traditional checkout flows weren't built for AI agents to use That's why the leaders created these 4 commerce protocols... As AI agents have evolved from answering questions to making real purchases. While these purchases are autonomous, the industry has developed specialized protocols to handle each agent-driven commerce safely. 📌 Here are the 4 emerging protocols enabling secure agent transactions: \1 ACP (Agent Commerce Protocol) - Built by: OpenAI & Stripe - Enables agent checkout through shared payment tokens - Perfect for delegated shopping with user approval How it works: → Agent initiates purchase flow on behalf of user → Buyer reviews and approves product selections → Agent shares Shared Payment Token (SPT) with merchant → Merchant charges via existing payment processors \2 AP2 (Agent Payment Protocol) - Built by: Google - Creates mandates for trusted, recurring agent payments - Uses verifiable credentials across cards, banks, and stablecoins - Designed for pre-authorized agent spending How it works: → Capture user intent for purchase (Intent Mandate) → User signs mandate with payment constraints → Link payment method to verified mandate → Execution happens automatically within signed rules \3 TAP (Trusted Agent Protocol) - Built by: VISA - Verifies agent identity and intent before transactions - Adds trust layer to any existing payment system How it works: → Agent sends cryptographically signed intent to merchant → Merchant verifies signature using Visa's public keys → Once verified, proceed with normal checkout flow → Rail-agnostic layer that works with any payment system \4 X402 (X402 Coinbase Protocol) - Built by: Coinbase - HTTP-based onchain pay-per-use for AI services - Uses EIP-712 signed payloads with stablecoins (USDC on Base) - Built for microtransactions and API monetization How it works: → Server returns 402 status code with payment terms → Client pays via facilitator using stablecoins (USDC) → Payment verified on-chain with E
