Otto AI

Structured token fundamentals by ticker symbol (resolves to the top-market-cap asset matching it): price, market cap, FDV, rank, 24h volume, full supply breakdown (circulating/total/max), ATH + drawdown from ATH, ATL + recovery, ROI windows (24h/7d/30d/60d/1y), categories, and project links — clean JSON an agent can consume field-by-field. Fundamentals snapshot, not a streaming price feed.

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/token-fundamentals", { method: "GET" });
console.log(await res.json());
