AI agents are moving beyond generating responses. They’re starting to pay for services and participate in digital economies. But how does an autonomous payment actually work? With x402 on @Concordium, an agent can receive payment requirements, authorize a stablecoin transfer, and work with a facilitator to complete the transaction. The key distinction: stablecoins settle the service payment, while CCD covers the separate network fee in a sponsored transaction. The facilitator pays the fee; it isn’t eliminated. As AI agents become more autonomous, payment infrastructure, identity, and accountability all matter. One request. Two financial flows. A clearer path to autonomous payments.
