Today, when we asked our AI system “What is x402 error code?” — it made us pay 0.05 USDC on Saga before answering. @Sagaxyz__ (gasless!)
The x402 is built on the HTTP 402 Payment Required code — a long-reserved status now being used for internet-native payments.
- Works across blockchains 🪐:
- Lets APIs and resources request payment instantly
- Turns the web into a pay-as-you-go ecosystem
"The x402 error code is a signal that a payment is required to complete an API request or load a resource [1,2,3,4,5]. It utilizes the long-reserved HTTP 402 "Payment Required" status code [1].
The x402 protocol is a chain-agnostic standard for payments on top of HTTP, leveraging the existing 402 Payment Required HTTP status code [3].
This protocol is used to enable internet-native payments using the HTTP 402 status code [5]." @CoinbaseDev @yugacohler
Up next, $DND and Solana!
