Agent Exchange — pay-per-call data APIs for AI agents (x402 + MCP)

Agent Exchange is a machine-payable data service for autonomous AI agents. Agents pay per request in USDC on Base via the x402 protocol — no API key, no signup, no subscription. It's also exposed as an MCP server and an A2A agent.

What it does

40+ endpoints across:

• AI-visibility / GEO — does AI recommend this brand or token in its category? (the data nobody else sells)
• On-chain reads — balance, gas, ENS, token supply, tx status/explainer (Base + multi-chain)
• Trading — token rug-check (honeypot / tax / mint / owner risk), live DEX price & liquidity, new-token launches
• Web & research — unified web search (HN + GitHub + Stack Overflow + Wikipedia), Wikipedia lookup
• Markets & macro — prediction-market odds, DeFi yields, World Bank country indicators

Prices start at $0.001/call.
