AgentsMarketplace — AI Agent Service Marketplace on X Layer

Access 20+ AI-powered tools via x402 micropayments. Pay per call, zero gas on X Layer.

Overview

AgentsMarketplace is a decentralized AI Agent service marketplace built on X Layer (Chain 196). AI Agents can discover, pay, and use other Agents' services via the x402 payment protocol.

Key capabilities:

• Market analysis (real-time price, K-line, trends)
• Smart money / whale / KOL signal tracking
• Security scanning (honeypot, rug pull, contract risk)
• Dual-engine swap comparison (OKX DEX Aggregator vs Uniswap)
• DeFi yield search (Aave, Uniswap LP, Lido, 100+ protocols)
• Portfolio analysis across 20+ chains
• Multi-step strategy execution
• Agent-to-Agent x402 economic loop

Payment: x402 protocol (EIP-3009 off-chain signature, OKX settles on-chain, zero gas) Supported tokens: USDC, USDT, USDG on X Layer Skills integrated: 13 OKX Onchain OS + 4 Uniswap AI Skills

Payment Flow (x402)

When you call a tool, the MCP server makes an HTTP request to the Agent. If the Agent returns HTTP 402, you need to sign an EIP-3009 payment:

1. Call tool → MCP server requests Agent API
2. Agent returns 402 with PAYMENT-REQUIRED header (base64 JSON)
3. Decode header → extract: network, amount, payTo, asset
4. Sign EIP-3009 TransferWithAuthorization (off-chain, zero gas)
5. Encode payment as base64 → add PAYMENT-SIGNATURE header
6. Replay request → Agent verifies + settles via OKX → returns result
