Price From Surface

When to use: you already have an IV surface (k,T,σ) and need to price options on it — not invert premiums and not scalar σ. Interpolates total variance w=σ²T bilinear in log-moneyness k=ln(K/F); wingRule=flat_vol. Returns price, interpolated σ, k, F, BS Greeks. USDC exact on Solana/Base. Prefer /v1/option/price when σ is a single scalar.

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://derivatives-pricer-production.up.railway.app/v1/option/price-from-surface", { method: "POST" });
console.log(await res.json());
