#cardano纳入x402套件支持ada支付
The code of the Cardano Foundation has been officially merged into the x402 official SDK. Developers can now complete API payments directly via HTTP requests using ADA or any Cardano-native token—no accounts, no API keys, and no subscription fees. This is a flare of signal that Cardano has thrown into the machine economy track.
Why is this worth getting excited about? x402 awakens the long-sleeping HTTP 402 “Payment Required” status code, enabling AI agents to complete the full flow—“discover price → sign transaction → fetch data”—within a single request-response cycle. Cardano’s eUTxO model is naturally suited to this scenario: transactions are signed by the user, and payment and payment proof are baked into the same cryptographic step.
But don’t get too carried away. The reality is: x402 has accumulated over 120 million transactions, Base about 70 million, and Solana about 45 million—while Cardano’s data is currently zero. The Facilitator has only completed a real transaction on the pre-production network; mainnet deployment hasn’t started yet. Cardano DeFi TVL is about $65 million, whereas Solana’s x402 alone has handled more than 35 million transactions.
The gap is glaring, but the direction is right. What the Cardano Foundation engineers delivered isn’t just an adapter, but a complete client, server, and coordinator components—along with reusable example code. Support for native stablecoins like USDM, DJED, and iUSD means AI agents can buy weather data without being exposed to ADA’s volatility. First release in TypeScript, with Python on the way
