Crossmint launches Agentic Cards API for US-issued Visa cards

Crossmint has launched a new API that lets developers connect eligible US-issued Visa credit and debit cards to agent systems, using Visa Intelligent Commerce and Basis Theory as the payments backbone. For high-risk PSPs, the important bit is straightforward: this is another attempt to make card-funded agent payments work without exposing raw card data to the agent layer.

1. Crossmint says the new Agentic Cards API is designed for agents in OpenClaw, Claude Code, Hermes, Zo Computer, and other agentic platforms to pay with supported Visa cards. The API is aimed at developers building payment functionality for AI agents rather than end users plugging in cards directly.
2. The setup uses Visa Intelligent Commerce Connect to create tokenized credentials and apply existing Visa cards for agentic payments with controls in place. Crossmint says card numbers and CVCs are not revealed to or stored by third-party services, and that vaulting plus tokenization keep sensitive data out of the agent environment, which is the part PSPs will care about when assessing PCI exposure.
3. Crossmint co-founder Alfonso Gómez-Jordana Mañas said the company is trying to provide “a secure, open payment layer” that works “for every agent, on every platform.” In practice, that means the payment method is scoped and controlled by the user rather than handed over in a form the agent can freely inspect.
4. Basis Theory, described as Visa’s fintech partner in the stack, provides the secure payments and sensitive-data infrastructure layer. Colin Luce, co-founder and CEO of Basis Theory, said the model keeps credentials vaulted while agents transact and only receive access to the data they are authorised to access.
5. Crossmint also rolled out the same capability inside lobster.cash, its own payment solution for AI agents. Lobster.cash can be embedded in platforms like Claude Code, OpenClaw, Hermes, and Zo Computer, and lets users issue a virtual card with set spending limits or assign an AI agent to a stablecoin wallet. When agents find products, subscriptions, or services to buy on behalf of the client, they request access to a payment method rather than being given unrestricted card data.

Crossmint says a review of published OpenClaw skills found exposed card credentials in 7.1% of cases. That is not a huge share, but it is enough to explain why card networks, PSPs, and compliance teams are treating agentic commerce as a data-handling problem first and a product feature second.
