Crossmint has launched a card vault for developers building AI shopping agents. Announced on September 17, the SDK collects card details inside the developer’s own interface, sends them to a vault and returns a token, according to the company.

Crossmint says eligible cards can use Visa Intelligent Commerce or Mastercard Agent Pay to provide an agent with a limited-use payment credential. The proposed controls include an expiry and a spending limit set by the user.

Availability needs careful reading. The vault is described as live, while the separate Agent Checkout product remains in pre-release. Crossmint says that product is intended to support purchases through browser automation, merchant APIs and agentic-commerce protocols.

For gift-card operators, the distinction is between securing a payment credential and making an existing merchant balance spendable. The announcement does not establish support for checking a closed-loop gift-card balance or splitting an order between that balance and another payment method.

The next practical question is which cards and checkout paths an integration actually supports. A launch announcement for card storage is useful evidence of progress, but it does not establish universal acceptance or gift-card redemption.
