http-status-checker.underscoredone.com
Give this API a list of up to 10 web addresses and it will visit each one to tell you whether it is working, broken, or redirecting visitors somewhere else. You get back the exact status number (like 200 for OK, 404 for not found, 500 for server error), whether the address redirects, and where it redirects to. Great for finding broken links, verifying website migrations, and running quick SEO audits without writing any code.

qr-code-generator.underscoredone.com
Send a list of texts — website addresses, phone numbers, plain words, WiFi details, anything — and get back a ready-to-use QR code image for each one. Every QR code comes as a base64-encoded PNG you can drop straight into a webpage or save to disk. Great for marketing campaigns, event tickets, product labels, menus, or any situation where you need many QR codes in one go. Empty entries are quietly skipped. Each input is limited to 700 characters. You must send at least one non-empty entry.

sitemap-url-extractor.underscoredone.com
Give this API a link to any website's sitemap.xml file and it will fetch and parse it, returning every URL found inside.

Each URL is returned with any extra information available, such as when the page was last updated and how often it changes. Useful for SEO audits, content inventories, broken link checks, and competitive research.
