x402 Web Tools

Encode text or a URL as a QR code: PNG (base64 and a data URL) or SVG, with the size and error correction level you choose.

Extract the text of a PDF at a public URL, page by page, with its title, author and page count. Up to 10 MB; scanned PDFs without a text layer return little text.

Title, description, canonical URL, language, author, published and modified dates, favicon, RSS and Atom feeds, Open Graph and Twitter card tags, JSON-LD structured data and the h1/h2 outline of a public web page.

Check a web page for changes: each call compares the page's readable text with your previous check of the same URL (kept per paying wallet for 90 days) and returns whether it changed, when you last checked, and the added and removed lines. The first call records the page. Use name to keep several watches of one URL apart.

Every distinct link on a public web page as absolute URLs with their anchor text, marked internal or external and nofollow, up to 500.

Request an https URL and report whether it is reachable, its status, every redirect hop with timings, key and security headers (HSTS, CSP and others), and the TLS certificate with its issuer, the names it covers and the days until it expires. An unreachable URL is a result too, with the reason.

A, AAAA, CNAME, MX, TXT, NS, CAA and SOA records of a domain from public resolvers (Cloudflare and Google), or just the types you ask for, and whether the domain exists.

Fetch a public web page and return its main content as clean Markdown (Mozilla Readability, as in Firefox Reader View, then Markdown with absolute links and tables), with title, byline, site name, published date, language, excerpt and a token estimate. Navigation, ads and footers are left out. Pages that cannot be read (errors, not HTML) are not charged.

The items of an RSS, Atom or RDF feed as JSON (title, link, id, published date, author, plain-text summary). Given a web page instead of a feed, it finds the feed the page links to.

The URLs a sitemap lists, with last modified dates, or the sitemaps a sitemap index lists. Given a site instead of a sitemap, it finds the sitemap from robots.txt or /sitemap.xml. Gzipped sitemaps are read too.
