Metadata API
Website metadata use cases
Recipes for link previews and website metadata extraction: custom fields next to Open Graph data, fixes for a missing og:image, single-page apps, brand colors, localized pages, bot-protected sites and unfurling at scale. One problem per page, with the code to run and a note on when a custom extraction rule is the better tool.
Use cases
Pick the problem you are solving
Custom fields alongside metadata
Get prices, ratings, headings or any CSS selector, typed and returned next to the normalized metadata.
Fix missing or wrong og:image
Override any normalized field with a rule and chain fallbacks so link previews never render empty.
Metadata from single-page apps
Render React, Vue or Angular apps in a headless browser, wait for the tags, then read the normalized metadata.
Link previews for bot-protected sites
Unfurl links to sites behind Cloudflare or DataDome by routing the metadata request through the built-in proxy.
Brand colors from images
Get the dominant palette and an accessible text and background pair from a site’s logo and preview image.
Link previews at scale
Unfurl links at any volume: no throttling, background refresh and cache hits that never count against your quota.
Only the fields you need
Include or exclude normalized fields per request and trim the JSON for faster, lighter metadata calls.
Region-specific metadata
Fetch titles, descriptions and prices as a visitor from a given country and language sees them.
Ready to extract metadata from any URL?
Every recipe on this page runs on the same endpoint. Start on the free tier, add an API key when you need proxies, custom headers or longer caching.
Other use cases

Mobile screenshots at any viewport
Emulate an iPhone, a Pixel, an iPad or any custom viewport and capture the page exactly as those visitors see it.
Screenshots without cookie banners or ads
Ads, trackers and consent popups are blocked before the page renders, and one option dismisses first-party banners.
PDF invoices from authenticated pages
Print the invoice page your app already renders: forward the session, hide the chrome, name the file.
Clean PDFs without ads or banners
Get a document, not a browser tab: ads and consent popups blocked by default, sticky chrome removed with one CSS rule.
Markdown with metadata frontmatter
Get each page as Markdown with a YAML frontmatter block: title, author, date, word count and reading time.
Clean Markdown, no boilerplate
Convert only the article body: one selector keeps navigation, ads and widgets out of the Markdown.
