Find the golden dog and alpha password in X402. Overview of x402 Protocol The x402 protocol is an open, HTTP based payment standard launched by Coinbase in September 2025, primarily utilizing the HTTP 402 "Payment Required" status code for instant, account independent on chain micro payments. X402 is designed specifically for AI agents, machine to machine (M2M) transactions, and automated economies, supporting stablecoins such as USDC and running on EVM chains such as Base/BNB chains and Solana chains. X402 core mechanism: The server returns a 402 response (including payment amount, token, and address), and the client submits payment proof through offline signature (such as ERC-20 transferWithAuthorization), achieving 200ms level settlement without the need for API keys or blockchain infrastructure. The x402 protocol is open source (Apache 2.0), maintained by the x402 Foundation, and has over 50 integrations, including facilitators such as Coinbase, Polygon, and PayAI. 2、 Key market information for the past week Market and adoption explosion ➤ Trading data: From October 21st to November 2nd, the total trading volume exceeded 4.1 million transactions, with a total value of 3.8 million US dollars.

Last week, the trading volume increased by 10780% compared to the previous week, and the total value of the ecosystem market soared from 280 million US dollars to 813 million US dollars (+187%). ➤ AI payment revolution: Starting from the end of October, x402 is regarded as the core of AI proxy payment infrastructure. The A16Z 2025 report emphasizes its role as the mainstream path for encryption, driving AI driven transactions. ZCloak Network demonstrated the world's first AI human collaborative stablecoin payment, using multi signature wallets and x402 for real-time supervision. ➤ Institutional endorsement: Coinbase officially integrates x402 into the Base chain, supporting NFT minting and microtransactions (such as x402 Loop NFT launch, 14242 total supply, USDC instant settlement). Solana ecosystem expansion, including http://radr.fun The ZK secure version (Groth16+ElGamal). Ecology and Emerging Applications ➤ AI agent tool: AgentBank provides interest free micro loans, which automatically intervene when the agent's funds are insufficient; InfraPay (@ infrapay_) API development, supports ZK secure cross platform transactions; AEON (@ AEON_Community) builds intelligent value transfer. ➤ NFT and gaming: x402 Loops NFT launch platform (http://(x402mkt. com)) enables real-time casting of USDC without gas surprises; SlotX402 demonstrates a real use case (1 USDC=1 slot machine spin, supports ETH/BTC). ➤ Other: DataLair (LAIR) integrates micro payments; Wach-AI serves as the validation layer and supports ERC-8004 on chain task validation; HeyElsa AI builds a proxy economy, endorsed by Magic Labs for tokenized AI roles such as Sam/Aifins. 3、 Investment opportunities X402 integrates AI+payment+Web3, which is in line with future trends and the AI proxy craze (OpenAI, etc.). As an "HTTP native payment" solution to the pain points of micro transactions (low fees, 2-second settlement), potential mainstream adoption (such as Google proxy search integration). X402 is shifting from meme frenzy to value infrastructure, and if adopted consistently, it will reshape digital payments. Meme is purely hype driven and emotion driven, focusing only on leading companies like Ping Focus on infrastructure, frameworks, and practical projects such as Payai BNKR $UB Kite.
