C# SDK-free

The Screenshot API for C#

Capture pixel-perfect screenshots from C# with a single HTTP request — no headless browser, drivers, or browser binaries to maintain.

Running your own headless Chrome for screenshots means managing browser binaries, memory spikes, zombie processes, and constant version churn. From C#, Screenshotty replaces all of it with one HTTPS call: send the URL and options, get the image back.

A few lines of HttpClient in .NET — no PuppeteerSharp browser downloads or Playwright driver installs on your build agents.

C# (HttpClient)

using System.Net.Http;
using System.Text;

var client = new HttpClient();
client.DefaultRequestHeaders.Add(
    "X-Api-Key", Environment.GetEnvironmentVariable("SCREENSHOTTY_API_KEY"));

var payload = new StringContent("""
    {"url": "https://example.com", "format": "image/png",
     "full_page": true, "block_cookie_banner": true}
    """, Encoding.UTF8, "application/json");

var response = await client.PostAsync(
    "https://api.screenshotty.link/api/v1/screenshot", payload);
response.EnsureSuccessStatusCode();

await File.WriteAllBytesAsync(
    "screenshot.png", await response.Content.ReadAsByteArrayAsync());

Everything You Need, Built In

One HTTP request

Any HTTP client works. GET with query params for simple captures, POST with JSON for complex ones.

Full rendering engine

Real Chrome rendering with full-page capture, custom viewports up to 4K, dark mode, and CSS-selector cropping.

Clean captures

Built-in ad blocking and cookie-banner blocking — no injected cleanup scripts to maintain.

Production-ready

Webhooks for async jobs, geo-targeted captures from multiple countries, and PDF/WebP/PNG/JPEG output.

Frequently Asked Questions

How do I take a website screenshot in C#?

Send an HTTP POST to https://api.screenshotty.link/api/v1/screenshot with the target url and your options, using your API key in the X-Api-Key header. The response body is the image itself — write it to disk or pipe it onward. No browser automation library is required.

Do I need Puppeteer, Playwright, or Selenium in C#?

No. The rendering happens on Screenshotty's managed Chrome fleet, so your C# app only makes an HTTP request. That removes browser binaries from your deployments and the operational work of scaling headless Chrome.

Can I capture the full page or just one element?

Both. full_page=true captures the entire scrollable page (use scroll_to_bottom for lazy-loaded content), or pass a CSS selector to capture a single element.

Is there a free tier?

Yes. 100 screenshots per month free, no credit card required. Paid plans start at $9/month for 2,500 screenshots with $0.004 pay-as-you-go overage.
