Cardano Integrates X402 to Bring ADA Payments to AI Agents
The integration gives developers client, server and facilitator tools for ADA payments, with end-to-end testing completed on Cardano preprod.
- Cardano has joined the official x402 software kit, enabling applications and AI agents to pay for online services using ADA through the HTTP "402 Payment Required" response.
- In 2025, Coinbase introduced the x402 protocol before moving it to an open standards effort supported by Google, Visa, and Mastercard, allowing software to purchase digital resources via web requests.
- Cardano Foundation engineers developed client, server, and facilitator components, though the software has only completed end-to-end testing on Cardano's pre-production network rather than mainnet.
- Coinbase reported in September that its developer platform processed more than 100 million x402 payments, while networks like Solana and XRP Ledger already support the standard with live deployments.
- Developers can begin incorporating available tools into applications now, as the pay-per-use model enables autonomous software to purchase data and computing capacity directly through web requests.
