Odaily Planet Daily reports that the x402 Gateway is now available on Mantle. Developers and creators can now access the x402 protocol through service providers and experience faster experimentation and building. x402 is an open protocol that defines an internet-native micropayment channel based on HTTP 402 and stablecoins. This allows automated clients and AI agents to pay for APIs, data, and computation on demand, enabling real-time, low-friction, and intermediary-free transactions.
