Audit Open Graph Tags Across Pages
Check whether pages are correctly set up for social sharing by auditing their Open Graph metadata.
Fetch Rich Metadata from URLs
Pull the title, description, thumbnail image, and Open Graph data from any public URL.
Quick answer: Use the Link Preview tool through ToolRouter to fetch rich metadata from urls directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolWhen you share a link in a messaging app, the preview that appears — the title, description, and thumbnail image — comes from Open Graph metadata embedded in the page. Accessing that data programmatically without visiting the page, parsing the HTML, and extracting the right tags is a non-trivial amount of work for a task that should be simple.
The preview_url skill fetches a URL and returns its structured metadata: page title, meta description, Open Graph title and description, thumbnail image URL, site name, and content type. You get the full preview data in one call.
Developers building link-sharing features, content teams curating external resources, and researchers building reference databases all use this to pull clean metadata from URLs without writing a custom scraper for every site format.
How to fetch rich metadata from urls with Claude, ChatGPT, Microsoft Copilot, and OpenClaw
Claude fetches link metadata and can immediately act on it — compare the Open Graph title to the actual page title, check whether the thumbnail is appropriate, or pull metadata from multiple URLs and present the results as a formatted summary.

How to fetch rich metadata from urls with Claude
Once connected (see setup above), use the Link Preview tool:
- Ask: "Get the link preview metadata for: [paste URL]"
- Claude returns the title, description, image URL, and Open Graph data
- Ask follow-up: "Is the description a good summary of the page?"
- Use the metadata to populate a link card, database entry, or content feed
Example prompt for Claude
Try this with Claude using the Link Preview tool
Fetch the link preview metadata for these three URLs and tell me the title, description, and whether each has a thumbnail image: [url1], [url2], [url3].
Tips for Claude
- Ask Claude to compare the Open Graph title vs the plain page title — discrepancies are common and worth knowing
- Fetch metadata for multiple competitor pages to see how they position content in link previews
- Ask whether the description is under 160 characters for SEO reference
ChatGPT fetches URL metadata and presents it in a readable format — useful for auditing how links appear when shared, building content catalogues, or checking whether a page is set up for social sharing correctly.

- Ask: "Get the link preview data for this URL: [url]"
- ChatGPT returns the structured metadata
- Ask: "Is the Open Graph description set, or is the page missing OG tags?"
- Use the results for content auditing or link card population
Example prompt for ChatGPT
Try this with ChatGPT using the Link Preview tool
Fetch link preview metadata for this URL and tell me what will appear when it is shared on social media: https://example.com/article
Tips for ChatGPT
- Ask ChatGPT to flag URLs that are missing Open Graph tags — they will generate poor link previews
- Use this to audit your own content pages before publishing or sharing
- Request a formatted link card summary showing exactly what the preview will look like
Copilot fetches URL metadata directly in your development environment — populate link cards in your application, validate Open Graph tags, and generate the integration code to add link preview fetching to your feature without leaving the editor.

Once connected (see setup above), use the Link Preview tool:
- In Copilot Chat: "Fetch the metadata for this URL: [url]"
- Copilot returns the title, description, and image URL
- Ask: "Write TypeScript code to call the preview_url skill and return a link card object"
- Integrate the metadata fetching into your link-sharing feature
Example prompt for Copilot
Try this with Copilot using the Link Preview tool
Fetch metadata for https://example.com and write a TypeScript interface and function that calls preview_url and maps the result to a LinkCard type with title, description, image, and url fields.
Tips for Copilot

- Ask Copilot to write fallback handling for URLs that return incomplete metadata
- Cache metadata results to avoid repeat fetches for frequently shared links
OpenClaw fetches link metadata in bulk — process a list of URLs, populate a content database with rich preview data, and run regular checks to keep metadata current as pages change.
