Alchemy & Visa AgentCard
Alchemy & Visa AgentCard is a payments and identity stack for AI agents, built on Visa Intelligent Commerce, that provisions a Visa payment token, dedicated email and phone, and a crypto wallet via one API for consumer-authorized transactions. It supports Visa-issued tokens by default, along with crypto, x402, and Stripe's Machine Payments Protocol, and is model-agnostic across OpenAI, Anthropic, and other frameworks.
