Quick Start

Your agent is 10 lines of code away from production SEO analysis.

// x402 fetch wrapper — handles 402 payment automatically
import { withPaymentInterceptor } from "x402-fetch";
import { createWallet } from "@solana/web3.js";

const fetch = withPaymentInterceptor(globalThis.fetch, { wallet: createWallet(PRIVATE_KEY) });

// Analyze any URL — agent pays $0.08 USDC automatically
const result = await fetch("https://api.nimrod.tools/v1/seo/analyze", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ url: "https://example.com" })
});

const { score, issues, recommendations } = await result.json();
// That's it. No API key. No account. Paid and done in 400ms.
