x402 APIPassing, checked 2 h ago

Live prediction-market odds from Polymarket — list the top active markets by volume, or search by keyword. Each result has the question, outcomes with current prices (implied probabilities), 24h/total volume, liquidity, and resolution date. No API key. Great for agents tracking real-world event probabilities (elections, crypto, sports, econ). Pass params as query (GET) or a JSON body (POST).

import { x402Client } from "@x402/core/client";
import { ExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client().register(
  "eip155:8453",
  new ExactEvmScheme(privateKeyToAccount(process.env.AGENT_KEY)),
