# What is 402Gate

**402Gate** is a decentralized **pay-per-use protocol** built on **Solana**, designed to bring back the long-forgotten HTTP status code \
`402 Payment Required` and reimagine it as a modern, blockchain-powered payment standard for the new Internet economy.

At its core, 402Gate transforms how applications, APIs, and AI agents exchange value.\
Instead of using subscriptions, tokens of access, or centralized payment gateways, 402Gate allows users (or autonomous agents) to pay **instantly and directly** for every API call, data query, or digital service with **no accounts, no intermediaries, and no friction.**

This is made possible through **on-chain verification**, **wallet-based identity**, and **multi-token micropayments** using **$402G**, **USDC**, or **SOL**.\
Each payment is validated and logged on Solana, ensuring transparency, auditability, and real-time settlement in under two seconds.

In simpler terms, 402Gate turns every web request into a **verifiable transaction** bridging the gap between Web2 usability and Web3 autonomy.
