Binance Says Agentic Payments Now Supports x402 Payment Flows | LeapRate
Binance said agentic payments now support x402 payment flows on BNB Chain for AI agents
It lets AI agents and apps pay for online services automatically, without needing a human to approve each transaction.
B402 is built on x402, a payment protocol that uses the HTTP “402 Payment Required” code. It allows businesses to charge for access to APIs, data, or content, while buyers, including AI agents, pay using stablecoins on BNB Smart Chain. Supported tokens include U, USD1, USDT and USDC.
The firm explained that when a client requests a paid service, the seller replies with a request for payment. The buyer then signs an approval off-chain, without needing to hold any crypto for gas fees. The seller sends this to B402, which verifies it and completes the payment directly on-chain between the two wallets. B402 covers the gas costs itself.
This setup is aimed at businesses that want to charge small amounts per API call, let AI agents pay for tools or data on their own, or put content behind simple pay-per-view style paywalls.
Sellers can also list their services on something called B402 Bazaar, making it easier for AI agents to find and pay for them automatically.
B402 is currently live on BNB Smart Chain’s test network, with companies able to apply for full access. Binance plans to bring the system to other blockchain networks in the future as demand grows for payments between machines and AI systems.
