Rain lets AI agents pay from a vault with one-task cards

Rain, a US payment company, launched Agent Vaults. The tool lets an AI agent pay, receive and send money from a balance that its owner funds. The owner sets the rules. For each purchase, Rain issues a card that works at 175 million merchant locations in 200 countries and territories. Rain gave no test results or use numbers.

How it works

The owner loads a balance by bank transfer, card or stablecoins. A stablecoin is a digital coin with a value that follows a currency. The agent gets a virtual Visa or Mastercard card for one task. Rain sets the limit, the merchant and the end date, and checks them when the card is used. The agent cannot increase its limit.

The example

Rain gives an example of a bakery owner who funds a vault with 5,000 dollars. Supplier purchases of 640 and 800 dollars go through. An equipment purchase of 2,400 dollars waits for approval, because it is not in the rules.

What is not known

This is an example from Rain, not a test result. Rain does not name the partners that use the tool. It says it works with agent developers, marketplaces and payment platforms.

Insight: Payment firms race to own the agent rules

Self Labs hides the card number from the agent. Crossmint sells one integration for the full purchase. Mastercard Agent Pay lets agents pay by card or stablecoin. Rain stays out of view: the name of the partner shows on statements, not the name of Rain. This reads as a race to hold the payment rules between agent and card network. Builders who pick a payment tool can also pick who holds those rules.
