Binance Says Agentic Payments Now Supports x402 Payment Flows
Binance says its agentic payments offering now supports x402 payment flows on BNB Chain, letting AI agents pay for services automatically with stablecoins.
Binance has expanded its agentic payments offering to support x402 payment flows on BNB Chain, enabling AI agents and applications to pay for online services automatically without human approval for each transaction.
The system, called B402, is built on x402, a payment protocol that leverages the HTTP "402 Payment Required" status 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.
Under the flow, when a client requests a paid service, the seller responds with a payment request. The buyer signs an approval off-chain, with no need to hold crypto for gas fees. The seller submits this approval to B402, which verifies it and executes the payment directly on-chain between the two wallets. B402 covers the gas costs itself.
The setup targets businesses that want to charge small amounts per API call, allow AI agents to pay for tools or data independently, or place content behind simple pay-per-view style paywalls. Sellers can also list their services on the B402 Bazaar, making it easier for AI agents to discover and pay for offerings automatically.
B402 is currently live on BNB Smart Chain's test network, and companies can apply for full access. Binance said it plans to bring the system to other blockchain networks in the future as demand grows for machine-to-machine and AI-related payments.
