To validate URL reachability, use a script that verifies a URL returns a successful HTTP status within allowed redirects. This checks HTTP headers and prevents broken links by returning actionable failure messages for 403, 404, or NXDOMAIN errors.

You can verify an image URL by running a validation script with the image flag to ensure the content-type is image/* and validate minimum byte sizes and dimensions. This prevents non-image links or thumbnails from known blocked hosts from appearing as usable visual content.

Yes, the URL validation script detects and avoids vulnerable redirects and SSRF-like paths. It ensures safe data handling by validating HTTP headers and redirect chains, returning actionable failure reasons when security checks fail.

Yes, you need Bun installed because the implementation uses Bun-based helpers alongside a Bash driver to ensure deterministic validation. The Bash script orchestrates the checks while Bun handles the underlying HTTP and content-type processing.

To enforce minimum image dimensions, run the check_url.sh script with the --image and --min-short-side flags followed by the image URL. This validates that the image meets your specified pixel threshold before allowing it in the output.

The best way to prevent broken image links is to validate URLs before replying by running a reachability script that checks HTTP status, content-type, and size requirements. This ensures embedded images will load correctly in a browser environment.
