Visa Brings Payment Rails Into ChatGPT for AI Agents

* Visa's Instant Checkout was retired in March after merchant fee problems; the ChatGPT integration rebuilds commerce on Visa's existing card-acceptance rails, removing the per-merchant fee barrier. * Visa's press release names three infrastructure layers absent from media coverage: Agent Score, Agentic Directory, and a Large Transaction Model trained on billions of transactions for fraud detection. * AP reporting notes most Visa-ChatGPT transactions will require human approval initially, qualifying the fully-autonomous framing that dominated headlines on launch day. Visa has plugged its payment network into ChatGPT, letting AI agents search and buy products on users' behalf at any Visa-accepting merchant. This replaces OpenAI's Instant Checkout, discontinued in March after a 4% merchant fee limited adoption to select merchants. Essentially: (Visa, OpenAI) pair Visa's authorization rails with ChatGPT's decision-making so agents complete checkouts, not just recommendations. - Most transactions initially require user notification and manual approval before completing. - Guardrails include spending limits, merchant whitelists, and approval steps. from : [https://aiweekly.co/alerts/visa-brings-payment-rails-into-chatgpt-for-ai-agents](https://aiweekly.co/alerts/visa-brings-payment-rails-into-chatgpt-for-ai-agents)
