POST /tools/broken-link-checker

live

Give it URLs. For each page it extracts every link and tests it (HTTP status), reporting broken links (4xx/5xx/unreachable) with their anchor text, plus redirects, and internal vs external counts. Keyless, threaded, read-only. Schedule + webhook to catch new broken links. Up to 3 items per call; failed lookups are not charged.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
