Deterministic finance and crypto math for AI agents: TradFi (NPV, IRR, XIRR, Black-Scholes + Greeks, bonds, VaR, Sharpe) and DeFi (impermanent loss, perp liquidation, funding, Uniswap v3, health factor, cost basis). Exact, model-free arithmetic that LLMs get wrong — priced per call in USDC.

Via direct x402 (advanced)Bring your own wallet
import { wrapFetchWithPayment } from "@x402/fetch";
import { createWalletClient, http } from "viem";
import { privateKeyToAccount } from "viem/accounts";
import { base } from "viem/chains";

const account = privateKeyToAccount("0xYOUR_PRIVATE_KEY");
const client = createWalletClient({ account, chain: base, transport: http() });
const x402Fetch = wrapFetchWithPayment(client);

const res = await x402Fetch("https://finmath.qzqh5rrbkz.workers.dev", {

  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ /* check provider docs for input */ }),
