SEO APIs.
An SEO API lets software read and act on search performance data programmatically — checking where a page ranks, auditing technical health, generating metadata, or pulling backlink and keyword figures — without anyone opening a dashboard. The alternative is scraping search results yourself and owning that scraper forever.

SEO Tags Generator API
SEO Tag Generator creates SEO meta tags from the content you send it. Submit a content string, and you can also set language and voicetone to guide the output. Use it when you need page-level metadata generated from article copy, landing-page text, or product descriptions. The POST endpoint starts an asynchronous job and returns a jobid plus a statusurl you can poll. When the job completes, the status endpoint returns the job id, type, and current status. On success, it includes result.metatags with fields such as title, description, keywords, author, og:title, og:description, og:image, og:url, og:type, og:site_name, twitter:card, twitter:title, twitter:description, twitter:image, and twitter:creator. SEO Tag Generator fits into content publishing workflows, CMS tooling, and internal marketing automation where you need structured meta tags without hand-writing each field.
