Check All Links on a Website

Broken links are an embarrassment and an SEO problem. Finding them means crawling the site, extracting links, and checking each one. denkbot.dog handles the crawling and link extraction part — you wire up the status code checking logic. The dog finds the links. You decide which ones are broken.

How it works

example

// Step 1: Crawl to get all pages
const crawl = await fetch('https://api.denkbot.dog/crawl', {
  method: 'POST',
  headers: { 'Authorization': 'Bearer YOUR_API_KEY', 'Content-Type': 'application/json' },
  body: JSON.stringify({ url: 'https://example.com', maxPages: 100 }),
}).then(r => r.json())

// Step 2: Scrape each page and extract links
const allLinks = new Set()
for (const page of getAllUrls(crawl.tree)) {
  const { links } = await scrape(page)
  links.forEach(l => allLinks.add(l.href))
}

// Step 3: Check each link
const results = await Promise.all(
  [...allLinks].map(href =>
    fetch(href, { method: 'HEAD' })
      .then(r => ({ href, status: r.status, ok: r.ok }))
      .catch(() => ({ href, status: 0, ok: false }))
  )
)
