Definition ∞ “Payment Required” is an HTTP status code (402) indicating that the client must first make a payment to access the requested resource. While not widely used in standard web browsing, it is reserved for future use in digital payment systems. In the context of digital assets, this concept can be applied where access to certain data, services, or computational resources on a blockchain is contingent upon a specific token transfer. It signifies a prerequisite for access.
Context ∞ While the HTTP 402 status code has limited current use, the underlying concept of “payment required” is fundamental to many blockchain protocols and decentralized applications, where gas fees or token payments are necessary for transaction execution or service access. Discussions in crypto news often revolve around transaction costs and economic models that necessitate payments for network resources. Future applications of this HTTP status code could formalize micropayment systems for digital content or API access.
