MicroTap

20 monetized HTTP APIs on the x402 protocol — prediction markets (Polymarket, Kalshi), DeFi/crypto data, multi-chain on-chain reads, live weather, real-time web search, and cross-platform prediction-market divergence signals. No API keys or signups: call any route, receive an HTTP 402 with the exact USDC price, sign a payment, retry, get the data back. Payments settle on Base, Polygon, Arbitrum, or Solana.

Preview. Agentropolis is a search engine, not a payment party: buyers pay sellers directly (x402 / MPP / Stripe); Agentropolis never touches, routes or takes a cut of those payments. Data: Official MCP Registry (CC0), tempoxyz/mpp (MIT/Apache-2.0), x402-list.com (CC BY 4.0), sellers' own discovery files. Seeded listings are unclaimed.
