curl -i "https://agent402.tools/api/meta?url=https%3A%2F%2Fexample.com"

The response is HTTP 402 Payment Required with exact payment requirements. Any x402 v2 client pays automatically and retries:

Paid call (JavaScript agent)

import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/meta?url=https%3A%2F%2Fexample.com");

Part of these workflows

This tool is one step in 6 curated multi-tool workflows - agents can fetch the whole sequence as an MCP prompt or call https://agent402.tools/api/skill-packs/{slug}/prompt.

• Content extraction - Turn arbitrary URLs and PDFs into clean structured text - articles, page metadata, PDF pages, OCR'd images, browser-rendered SPAs.
• Link preview card - The 'turn a URL into a card-shaped preview' workflow. Pull OpenGraph/Twitter card metadata, fetch the article body as a description fallback, normalize the og:image into a standard 1200×630 social card variant and a 400×400 square thumbnail, and extract URL/mention entities from the body for related-link surfacing. Five tools, one structured card payload ready for chat embeds, social shares, or RSS-to-card pipelines.
• Technical SEO audit - Can search engines and AI crawlers actually index this page? One pass over reachability, TLS, robots policy, sitemap health, meta/OpenGraph tags, and the on-page link graph.
• Competitor scan - What's a competitor using? Tech stack, HTTP headers, WHOIS, and page metadata in one call.
• Page audit - Full page SEO + security audit: content extraction, metadata, HTTP headers, robots policy, and sitemap health in one call.
• URL inspector - Quick URL health and metadata check - parse the URL structure, verify reachability, and pull page metadata in one pass.
