Summary
Cardano has been added to the official x402 software kit, allowing developers to build apps and AI agents that pay for online services with ADA or Cardano-issued tokens. The x402 standard enables automated, pay-per-use transactions within internet requests, eliminating the need for accounts, card details or subscriptions. Cardano’s TypeScript release has completed a transaction on a preproduction network, but it has not yet operated on mainnet or demonstrated commercial payments at scale.
