Mastercard Opens Early Access to AI Agent Payments After Coinbase, Base Pilots

The notable shift here is that agent-initiated payments are moving from pilot partners into an early-access product, which puts card-network rails in direct conversation with the crypto infrastructure Coinbase and Base bring to the table. The parties most affected are the merchants and payment processors that would need to accept and reconcile machine-originated transactions, plus the wallet and agent developers building on these pilots. Whether early access translates into broader production use — and how disputes, authorization and liability get handled when an AI agent, not a person, initiates a payment — is the open question worth watching.
