Developer Tools APIs.
Developer tool APIs are the small utilities every service ends up needing — format conversion, IDs, hashes, token decoding, DNS and WHOIS lookups. Hosted so they don't become twelve copy-pasted helpers across your repos.

ApyHubVerifiedHosted on ApyHubAudit Website SEO API
Website Audit lets you create, inspect, and manage site crawls for SEO and technical health checks. Send a domain and crawl settings, then track the audit as it moves through queued, processing, and finished states. Use the standard audit endpoint for an HTML crawl or the advanced audit endpoint when you need JavaScript rendering. Both accept a domain and an optional title, plus crawl settings such as maxpages, maxdepth, checkrobots, sourcesitemap, sourcesubdomain, ignorenofollow, ignorenoindex, and crawl limits like maxreq, maxsize, maxredirects, minwords, maxtitlelen, and maxdescriptionlen. The create endpoints return an id you can use across the rest of the API. Once an audit exists, fetch its status, full report, crawl history by date, crawled pages, found links, issue pages, or the issues for a specific URL. The list endpoint returns audit metadata such as url, title, status, stats, prevstats, lastupdate, and error; the report endpoint returns sectioned results with scorepercent, totalerrors, totalwarnings, totalnotices, and totalpassed. Website Audit is useful for scheduled SEO monitoring, release checks before publishing, and comparing crawl changes after fixes. You can also recheck an audit in standard or advanced mode.
