Site Health Scanner
Pricing
Pay per usage
Crawl a website to detect broken and problematic links, identify redirects and blocked URLs, capture screenshots, and return structured site health data for audits, automation, and monitoring.
url
Optional
The URL that was checked.
statusCode
Optional
HTTP status code (e.g. 200, 301, 404, 500). 0 means the request failed before a response (timeout, DNS, connection error).
status
Optional
Status category: OK, REDIRECT, BROKEN, BLOCKED, TIMEOUT, ERROR, SERVER_ERROR, CLIENT_ERROR, CRAWL_FAILED, or UNKNOWN.
confidence
Optional
Confidence that the status is accurate: high, medium, or low. External 403s are 'low' since they are often bot protection.
type
Optional
Whether the link is 'internal' (same domain as a start URL) or 'external'.
foundOnPage
Optional
The crawled page on which this link was found.
anchorText
Optional
Anchor text of the link, image alt text, or a resource marker. Null for crawl-failure rows.
responseTime
Optional
Response time in milliseconds. Null when the page could not be crawled.
redirectChain
Optional
Redirect chain joined with ' → ' when the link redirected, otherwise null.
screenshotUrl
Optional
Key-value store URL of a screenshot of a broken internal page, when captured; otherwise null.
error
Optional
Error message if the request failed (timeout, connection error, crawl failure); otherwise null.
warning
Optional
Warning text (mixed content, slow response, long redirect chain, bot-protection notice) or null.
isBroken
Optional
Definitive broken flag. True only for links that are actually broken (404/410, server errors, timeouts, connection/crawl failures, isolated internal 403s). False for blocked external links and bot-protected sites.
checkedAt
Optional
ISO-8601 timestamp of when this URL was checked.
