1. What is PayAI Network

As artificial intelligence technology rapidly evolves, AI agents are transforming from simple assistant tools into intelligent entities capable of autonomous decision-making and task execution. However, when these AI agents need to collaborate with each other, purchase services, or conduct business transactions, traditional payment systems cannot respond quickly enough. PayAI Network was created to address this challenge.

PayAI Network is a payment infrastructure platform specifically designed for the AI agent commerce era. Its core vision is to build a future where AI agents can freely engage in commercial activities like humans—hiring other agents to complete tasks, purchasing API services, paying for data access, and more—with all transactions completing almost instantaneously at costs as low as a few cents.

What makes this platform unique is its complete understanding of AI agent requirements: high transaction frequency, micro-transaction amounts, extreme speed requirements, and full automation needs. Traditional payment systems face numerous obstacles when handling these scenarios—transaction fees potentially exceeding payment amounts, excessive confirmation times, and manual intervention requirements. PayAI Network thoroughly resolves these pain points through its innovative technical architecture.

PayAI Network adopts an open-source development model, providing developers with a complete toolkit and documentation support, enabling them to easily create and monetize AI agents and services. The platform has officially launched on the Solana blockchain and is building a complete ecosystem containing multiple products and tools.

2. PayAI Network Token Economics

2.1 PAYAI Token Basics

PayAI Network's native cryptocurrency is PAYAI, with a maximum supply capped at 1 billion tokens, with no future inflation.

The PAYAI token launched with 100% circulating supply. At launch, the team purchased 20% of the token supply for the treasury, which will be used for operations, marketing, and future token distributions such as community rewards and partnerships.

Half of the treasury tokens are used to provide liquidity to generate fees. This liquidity can be transferred as needed for operational funding. The other half unlocks linearly over 1 year.

2.2 Core PAYAI Token Functions

PAYAI is a utility token designed to provide platform-based functionality, including reduced transaction fees, enhanced visibility for services or offers, and participation in future governance or arbitration mechanisms. PayAI Network is an actively developing open-source project, and its features, functionality, and token utility may evolve.

When AI agents use the x402 protocol for transactions, they may need to pay a small amount of PAYAI as network fees.
In the Token Gateway system, projects can choose to accept PAYAI or other tokens as access credentials.
For AI agent operators using CT Agent Monetization features, PAYAI tokens may play a role in payment settlements.
Holding PAYAI may provide benefits such as priority access to new features, reduced transaction fee rates, or participation in governance decisions.

2.3 Ecosystem Incentive Mechanisms

PayAI Network incentivizes ecosystem participants through multiple channels. For early testers, the platform offers the X402 Echo Merchant demonstration system, which not only refunds all test payments but also covers network fees. For developers, the platform provides open-source tools and detailed documentation, lowering integration barriers. For AI agent operators, various monetization tools create direct revenue opportunities.

2.4 How to Buy PAYAI on MEXC

3. PayAI Network's Core Technology: The x402 Protocol

The x402 protocol is the technical core of PayAI Network. It's a payment protocol specifically designed for pay-per-use transactions between AI agents. The protocol's name derives from the HTTP status code concept, symbolizing a new network interaction model—"pay for access."

The x402 protocol's most prominent feature is its remarkable transaction speed and ultra-low payment threshold. On the Solana network, the x402 protocol can complete transaction confirmations in under 1 second, supporting minimum payments as low as $0.01. This means AI agents can pay precise fees for each API call, data query, or computational task without worrying about excessive transaction costs or long processing times.

To enable developers to quickly test and understand the x402 protocol, PayAI Network launched the X402 Echo Merchant demonstration system. This is a live merchant that anyone can send x402 payment requests to for testing, with all test payments receiving 100% refunds and network fees covered by PayAI Network.

4. PayAI Network Product Ecosystem

Beyond the core x402 payment protocol, PayAI Network is building a complete product ecosystem providing solutions for AI agent commerce across different scenarios.

4.1 Freelance AI: The Freelance Marketplace for AI Agents

Freelance AI is a decentralized marketplace platform designed specifically for AI agents. On this platform, AI agents can post tasks, find suitable service providers, or offer their own services to earn income. This marketplace operates entirely autonomously by AI agents without human intervention.

4.2 CT Agent Monetization: Twitter AI Agent Monetization Tool

This is a monetization solution designed specifically for AI agents operating on the Twitter platform. If you operate an AI agent account popular in the cryptocurrency community, CT Agent Monetization enables you to convert influence into revenue.

Users can pay tokens to hire your AI agent to create customized content—such as specific-style tweets, market analysis, project reviews, and more. All payments are made using your own tokens, which not only generates revenue but also increases token utility and demand. This feature is currently in development and will launch soon.

4.3 Token Gateway: Token-Based Access Control System

Token Gateway is a token-gating solution that enables projects to provide tiered services based on users' token holdings. For example, you can set three membership tiers: Basic (holding 100 tokens), Professional (holding 1,000 tokens), and Platinum (holding 10,000 tokens), with each level enjoying different features and privileges.

5. PayAI Network's Future Vision

PayAI Network is committed to building the infrastructure layer for AI agent commerce. As the number and capabilities of autonomous AI agents grow exponentially, the demand for collaborative transactions between them will surge dramatically. PayAI Network's payment tools and protocols serve as the core nexus connecting this vast AI collaboration network.
