x402, an internet-native payments standard designed for artificial (AI) agents, is gaining significant traction across the cryptocurrency ecosystem and emerging as one of the most talked-about innovations in the space.
It’s not just attention. The ecosystem’s market capitalization also surged to over $800 million. As momentum continues to build, three small-cap tokens have benefited the most, standing out as the top weekly gainers within the x402 ecosystem.

1.AI Analyst (AIN)
AInalyst is an AI-driven Web3 analytics platform. It fuses on-chain metrics, social sentiment, and behavioral data to provide real-time insights for traders and agents.
The project is currently the top agent on x402, with the highest weekly returns of any token in the ecosystem. The altcoin has soared over 3,800% this week and hit a new all-time high yesterday.
At the time of writing, AIN was trading at $0.00259, up 13.4% in the past 24 hours. Its market capitalization is $2.6 million. Notably, the token was recently listed on Binance Wallet, expanding access for new users.
“You can now trade AIN directly on Binance Wallet and you can see it listed in the x402 category. Real data. Real utility,” the team posted.

2. PayAI Network (PAYAI)
PayAI Network is an open source marketplace where AI agents hire, contract, and operate autonomously 24/7. Networking accounts for approximately 14% of the x402 volume.
PayAI has a market capitalization of $59.1 million and is the third largest token in the x402 ecosystem. Over the past week, the token has soared more than 1,500%, hitting an all-time high before settling at $0.059. This equates to a 27% increase per day.
Market analysts have suggested that if current momentum continues, the project’s valuation could soon reach $100 million.
Analyst Alex predicted, “PAYAI has the upper hand in Solana. 100 million is still not far away. It will easily break through by the end of this week.”

Meanwhile, PayAI’s growth has been accompanied by some notable developments. Cryptocurrency exchanges Poloniex and Ju.com today announced the addition of trading support for PAYAI, enhancing liquidity and exposure.
At the same time, the network launched an airdrop campaign to reward early supporters and active users, allocating 1 million PAAI tokens for distribution. This development further encouraged community participation.
Nevertheless, Talentre DEX tools are warning of abnormal capital inflows into PAYAI, raising concerns.
“Our tool detected unusual inflows to PAAI, and they were flagged by real wallets with positive ROI, not wash trades. Once those wallets start selling, it’s time to exit the trade. We warned you!” Talentore posted.

3. Aurra by Virtuals (AURA)
Aurra by Virtuals rounds out this week’s top three. This platform provides AI agent tools and hosting designed for crypto applications. This enables seamless deployment and monetization of AI agents without the need for coding.
Aurra’s token, AURA, has risen 988.2% over the past week, reaching $0.0078 at the time of writing.
According to data from BeInCrypto Markets, its market capitalization is $7.8 million. The token is also listed on LBank and WEEX, expanding its accessibility for traders.
The rapid growth of AIN, PAAI, and AURA reflects both the opportunities and risks associated with new technology trends. While exchange listings, airdrops, and broad market participation are supporting the sector’s expansion, volatility could increase if profit-taking accelerates or weaknesses in the protocols emerge.
x402 Small Cap’s future results will depend on continued development, deeper integration, and AI-powered payments capabilities to achieve real-world efficiencies. The coming weeks will reveal whether today’s rally marks the beginning of a long-term trend or another declining meta in the crypto industry.
