B.AI, a financial infrastructure project dedicated to AI agents combining artificial intelligence (AI) and Web3, announced on the 10th that it has launched its global closed beta service. B.AI provides access to major AI models such as ChatGPT, Claude, and Gemini through a permissionless LLM gateway and integrated API that do not require a separate authorization process, and supports autonomous payments for AI agents based on the x402 payment standard and the 8004 on-chain identity protocol. B.AI explains that this aims to build an infrastructure that enables P2P transactions, automatic settlement, and trust-based collaboration between AI agents.
