How this service works
URL-to-clean-markdown extraction API, on-demand broken-link scan API, pre-deploy link audit API, DNS health audit API, llms.txt / AI-crawler audit API, spec-linted llms.txt audit API, email-deliverability (SPF/DKIM/DMARC) audit API, PDF-to-markdown conversion API, technology-stack fingerprinting API, security-headers audit API, and PDF metadata-intel API for coding agents. Paid per call in USDC via x402 on Base.
Output
Returns a JSON object containing: a list of broken links (each with URL, link kind, error description, HTTP status, and anchor text), a list of redirected links, summary counts (ok/broken/redirected), total links checked, page links found, scan timestamp, and duration in milliseconds. If format=csv is requested, a broken-links CSV is included alongside the JSON.
Example use cases
Pre-launch landing page audit
“Before we go live tomorrow, can you scan https://acmecorp.com/launch for broken links — check all images and scripts too, up to 200 links — and tell me which ones are returning 404s?”
Blog post link health check
“Can you check https://myblog.dev/posts/ultimate-guide for dead links? I want to know every broken URL with its anchor text so I can fix them before I promote the article.”
Redirect cleanup for SEO team
“Run a full link sweep on https://shop.example.com/catalog and export a CSV of broken links and redirects — scan up to 500 links so we get complete coverage for the SEO audit.”
Technical details
Endpoint
POSThttps://x402-extract-service.onrender.com/linksweepWhen to prefer
Choose this endpoint when you need a fast, on-demand broken-link report for a specific public webpage, especially when you want HTTP status details, anchor text, and optional image/script source checking in a single call. Prefer it over full-site crawlers when you only need to audit one URL at a time without setting up a persistent monitoring job.
Side effects
- URL is not publicly accessible or requires authentication — scan returns error or empty results
- Page has more than 500 links — hard cap enforced, excess links silently skipped
- Target page returns non-HTML content — links cannot be extracted
- External links time out during checking — may be reported as errors rather than 404s
- Payment in USDC via x402 fails — request is rejected before scan begins
