UrlPreviewParser

NuGet License: MIT

A .NET library for extracting link preview metadata (OpenGraph, Twitter Card, oEmbed) from URLs.

Installation

.NET CLI

dotnet add package UrlPreviewParser

Package Manager

Install-Package UrlPreviewParser

PackageReference

<PackageReference Include="UrlPreviewParser" Version="1.0.2" />

Quick Start

using UrlPreviewParser;

using var client = new UrlPreviewClient();
var result = await client.GetPreviewAsync("https://example.com");

// OpenGraph
Console.WriteLine(result.OpenGraph.Title);
Console.WriteLine(result.OpenGraph.Description);
Console.WriteLine(result.OpenGraph.Image);

// Twitter Card
Console.WriteLine(result.TwitterCard.Title);
Console.WriteLine(result.TwitterCard.Image);

// Basic page title
Console.WriteLine(result.Tags.Title);

Accessing the Data

OpenGraph (result.OpenGraph)

OpenGraphData extends Dictionary<string, string>. Any og:* property is accessible by key (e.g., result.OpenGraph["og:title"]). Convenience properties cover the most common fields:

Property Key
Title og:title
Description og:description
Image og:image
Url og:url
Type og:type
SiteName og:site_name

Twitter Card (result.TwitterCard)

TwitterCardData extends Dictionary<string, string>. Any twitter:* property is accessible by key (e.g., result.TwitterCard["twitter:label1"]). Convenience properties:

Property Key Notes
Card twitter:card e.g. summary, summary_large_image
Title twitter:title
Description twitter:description
Image twitter:image Falls back to twitter:image:src
Url twitter:url
Site twitter:site @username of the website
Creator twitter:creator @username of the content creator

oEmbed (result.Oembed)

Discovered oEmbed endpoint URLs and the raw response body:

Property Type Description
Json string? URL of the JSON oEmbed endpoint
Xml string? URL of the XML oEmbed endpoint
Formats List<string> Discovered format names (e.g. "json", "xml")
Body string? Raw response body from the oEmbed endpoint
Error string? Error message if the endpoint fetch failed

Tags (result.Tags)

Property Type Description
Title string? Content of the HTML <title> element
Images List<string> Image URLs found on the page

Raw head elements (result.Head)

result.Head is a List<Dictionary<string, string?>> containing the raw attributes of every child element of <head>. Useful when you need access to tags not covered by the typed properties.

Using Your Own HttpClient

When using dependency injection, pass your HttpClient directly. The caller is responsible for its lifetime; UrlPreviewClient will not dispose it.

// ASP.NET Core — register via IHttpClientFactory
builder.Services.AddHttpClient<MyService>();

// Then inject and use
public class MyService(IHttpClientFactory factory)
{
    public async Task<UrlPreviewResult> GetPreviewAsync(string url, CancellationToken ct)
    {
        var httpClient = factory.CreateClient();
        using var client = new UrlPreviewClient(httpClient);
        return await client.GetPreviewAsync(url, ct);
    }
}

Offline Parsing

ParseAsync parses metadata from an HTML string without making any HTTP requests. The oEmbed endpoint is discovered but not fetched.

using var client = new UrlPreviewClient();
var result = await client.ParseAsync("https://example.com", htmlString);
