Visa Trusted Agent Protocol (TAP)

Visa protocol that lets merchants authenticate trusted AI shopping agents via cryptographic signatures, with x402 interoperability into traditional payment rails.

Website ↗

Overview

Visa's Trusted Agent Protocol (TAP) is an agentic commerce protocol, developed with Cloudflare, that helps merchants distinguish legitimate AI agents from bots and fraudsters using agent-specific cryptographic signatures and additional agent-supplied context. Visa has added x402 support through TAP and is collaborating with Coinbase to make it interoperable with the x402 standard, bridging agent transactions to traditional Visa payment rails.
