Lint hreflang annotations
Lint hreflang annotations for international SEO. Accepts pasted text (not a URL; this tool never fetches anything): page HTML with <link rel="alternate" hreflang> tags, an XML sitemap with xhtml:link alternates, or a JSON set {"pages":[{"url","canonical","alternates":[{"hreflang","href"}]}]}. Checks language/script/region codes, x-default, self-reference, canonical conflicts, duplicates and reciprocal return links. Returns valid true/false, counts, the codes found, and up to 25 issues with paths, messages and suggested fixes. Read-only. Same engine as the HrefGate JSON API (POST /api/lint).
