Day movers for tokenized US stocks and ETFs on TWO rails in one call: Robinhood Chain (chainId 4663) and Base B20 (38 Coinbase-issued tokens, keyed by token address). Gainers and losers by REAL day-over-day change of the UNDERLYING stock vs the prior NYSE session close (Finnhub quotes), per-rail coverage counts; withdrawn tokens named with a reason, unquotable ones counted. Off-hours values freeze

This API is run by its own provider and paid directly through x402. We list it so you can find it; we don't route or hold the payment.

import { x402Client, wrapFetchWithPayment } from "@x402/fetch";
import { registerExactEvmScheme } from "@x402/evm/exact/client";

const client = new x402Client();
registerExactEvmScheme(client, { signer: agentAccount });

const pay = wrapFetchWithPayment(fetch, client);
const res = await pay("https://x402.ottoai.services/tokenized-stock-movers", { method: "GET" });
console.log(await res.json());
