The exact response handling depends on the provider: one API may return JSON with a screenshot URL, while another sends the image itself.
How the request moves through your application
- A client sends a target URL to your Express endpoint, such as
POST /screenshot. - Your route checks the request body and applies your access and URL policies.
- Server-side code sends the URL and capture options to the screenshot provider, authenticating with a key kept on the server.
- Your route checks the provider’s response and returns a screenshot URL, image bytes, or a suitable error to its caller.
Express associates route handlers with an HTTP method and path, and express.json() parses JSON request bodies. If middleware neither ends the response nor calls next(), the request can hang; see the Express middleware guide and routing guide.
Build the Express route safely
Install Express in your project, then add JSON parsing, URL validation, a server-side provider call, and centralized error handling. The example below uses Node.js’s built-in fetch and Screenshot API’s documented JSON response shape. Store the key in an environment variable; do not accept it from the client or commit it to source control.
import express from 'express';
const app = express();
app.use(express.json({ limit: '10kb' }));
function parseTargetUrl(value) {
if (typeof value !== 'string' || value.length > 2048) return null;
try {
const target = new URL(value);
if (target.protocol !== 'http:' && target.protocol !== 'https:') return null;
return target;
} catch {
return null;
}
}
app.post('/screenshot', async (req, res, next) => {
try {
const target = parseTargetUrl(req.body?.url);
if (!target) {
return res.status(400).json({ error: 'Provide a valid HTTP or HTTPS URL.' });
}
if (!process.env.SCREENSHOT_API_KEY) {
return res.status(500).json({ error: 'Screenshot service is not configured.' });
}
const controller = new AbortController();
const timer = setTimeout(() => controller.abort(), 90_000);
let response;
try {
response = await fetch('https://api.screenshot-api.org/api/v1/screenshot', {
method: 'POST',
headers: {
Authorization: `Bearer ${process.env.SCREENSHOT_API_KEY}`,
'Content-Type': 'application/json',
},
body: JSON.stringify({
url: target.href,
viewport: { width: 1280, height: 720 },
format: 'png',
fullPage: true,
}),
signal: controller.signal,
});
} finally {
clearTimeout(timer);
}
if (!response.ok) {
const status = response.status;
const appStatus = status === 401 ? 502 : status === 429 ? 503 : status === 400 ? 422 : 502;
return res.status(appStatus).json({ error: 'Screenshot provider could not complete the capture.', providerStatus: status });
}
const data = await response.json();
if (typeof data.screenshotUrl !== 'string') {
return res.status(502).json({ error: 'Screenshot provider returned an unexpected response.' });
}
return res.json({ screenshotUrl: data.screenshotUrl });
} catch (error) {
if (error?.name === 'AbortError') {
return res.status(504).json({ error: 'Screenshot request timed out.' });
}
return next(error);
}
});
app.use((err, req, res, next) => {
if (res.headersSent) return next(err);
console.error(err);
res.status(500).json({ error: 'Unable to process screenshot request.' });
});
app.listen(process.env.PORT || 3000);This example assumes an ES-module project and a Node.js release with built-in fetch. Its provider URL, bearer authorization, JSON body, and screenshotUrl property follow Screenshot API’s documentation; confirm the current contract before deployment. The timeout is an application-side ceiling, not a claim about provider processing time. For production, also add caller authentication or rate limits as appropriate and decide which target hosts your application should permit.

What to return to your caller
Returning { "screenshotUrl": "..." } keeps the response small when the provider supplies an image URL. If your provider returns image bytes instead, do not call response.json(): read the response as an ArrayBuffer or stream and send it with the correct content type, such as image/png. Check the provider’s documented status, content type, and response format before forwarding anything.
Provider contracts and options to check
These examples illustrate different response contracts, not a performance ranking. Provider documentation is the authority for its current endpoint, authentication, options, quotas, and error behavior.

| Service | Request and response documented | Capture and operational details |
|---|---|---|
| ScreenshotNeo | One GET request to its API returns PNG, JPEG, WebP, or PDF; API base: https://api.screenshotneo.com/v1/shot. |
Its features include full-page capture, element selection, viewport and device settings, waits, custom headers and cookies, PDF options, caching, bulk capture, async jobs, and an MCP server. Only clean shots are billed; failed loads, bot checks, blank pages, and cache hits are not billed. |
| Screenshot API | Bearer-authenticated POST to /api/v1/screenshot; documented example reads JSON property screenshotUrl. |
Options include format, viewport, full-page capture, selector, wait conditions, delay, and timeout. Its documentation, accessed in 2026, lists a free plan with 60 requests per minute and 500 screenshots per month; verify current limits. Documented errors include 401, 400, 429, and 502. |
| RenderScreenshot | Bearer-authenticated POST to /v1/screenshot; its Node.js SDK example writes returned bytes to a file. |
Documented output formats include PNG, JPEG, WebP, and PDF. Its listed use cases are vendor-described and do not establish independent performance. |
| Screenshot API.net | Direct HTTP capture returns raw image bytes; documentation says no SDK is required. | Its documentation describes refusing private and reserved destinations, including loopback, link-local, and cloud metadata endpoints. This safeguard is specific to that service; do not assume every provider blocks the same destinations. |
When selecting an API, compare its request style and SDK support, whether it returns a URL or bytes, its capture controls, documented errors and rate limits, network safeguards, and the limits and throughput your workload requires. Documentation alone does not establish relative speed, reliability, or screenshot fidelity.
Validate URLs and protect the route
URL parsing and an HTTP/HTTPS scheme check catch malformed or unsupported input, but they do not by themselves stop a user from requesting an internal system through a hostname or redirect. A general-purpose capture endpoint can become a way to probe destinations reachable by the rendering service.

- Require authentication and enforce per-caller limits if the endpoint is not intended to be public.
- For untrusted callers, consider an allowlist of domains rather than accepting every public URL. Account for redirects and DNS resolution in your threat model.
- Check the selected provider’s documented network restrictions. Screenshot API.net, for example, states that it refuses private and reserved destinations, but that behavior is not a universal guarantee.
- Keep provider credentials server-side, avoid logging authorization headers, and return sanitized errors rather than raw provider bodies or secrets.
- Set request-body and execution time limits so malformed or stalled requests do not consume resources indefinitely.
Return image bytes when the provider sends a binary response
For a provider whose documented endpoint returns raw image bytes, the route can forward the binary response rather than parsing JSON. This pattern uses a placeholder endpoint and environment variable because the exact URL, authentication header, and accepted parameters vary by provider; replace them with that service’s documented values.
app.post('/screenshot-bytes', async (req, res, next) => {
try {
const target = parseTargetUrl(req.body?.url);
if (!target) return res.status(400).json({ error: 'Provide a valid HTTP or HTTPS URL.' });
const controller = new AbortController();
const timer = setTimeout(() => controller.abort(), 90_000);
let upstream;
try {
upstream = await fetch(process.env.SCREENSHOT_BINARY_ENDPOINT, {
method: 'POST',
headers: {
Authorization: `Bearer ${process.env.SCREENSHOT_BINARY_API_KEY}`,
'Content-Type': 'application/json',
},
body: JSON.stringify({ url: target.href }),
signal: controller.signal,
});
} finally {
clearTimeout(timer);
}
if (!upstream.ok) {
return res.status(502).json({ error: 'Screenshot provider could not complete the capture.' });
}
const contentType = upstream.headers.get('content-type') || '';
if (!contentType.startsWith('image/')) {
return res.status(502).json({ error: 'Screenshot provider did not return an image.' });
}
res.set('Content-Type', contentType);
return res.send(Buffer.from(await upstream.arrayBuffer()));
} catch (error) {
if (error?.name === 'AbortError') return res.status(504).json({ error: 'Screenshot request timed out.' });
return next(error);
}
});Forward only content types and formats that your endpoint intends to serve. If the provider returns a PDF, JSON error, or redirect instead of an image, handle that according to its contract rather than labeling it as an image.

Troubleshoot failed captures
- 401 Unauthorized: the provider documents this for a missing or invalid key. Check that the server process has the expected environment variable and that the key is valid; never print the key in logs.
- 400 Invalid request: verify the submitted URL and option names/types against the provider schema. The example’s
viewport,format, andfullPageare provider-specific fields. - 429 Rate limit or quota: check the account’s current allowance and request rate. Queue or slow calls when appropriate instead of retrying immediately in a tight loop.
- 502 Render failure: the provider documents this for a failed render. Check that the target is reachable by the service and that your requested capture settings are supported; return a safe application-level error to your caller.
- 504 from your Express route: the local abort timer elapsed. Review your chosen timeout and whether the target or provider is slow; do not assume that raising the timeout will fix a provider-side failure.
- Unexpected JSON parse error: the provider may have returned bytes or a non-JSON error. Inspect status and content type before parsing, and align the route with the documented response shape.
- Caller receives an empty or wrong-format image: check whether the upstream response is binary, whether you forwarded the correct content type, and whether the provider actually returned a successful capture.
Or skip the browser setup
With ScreenshotNeo, your Express server can make one GET request to receive a screenshot without managing a browser. It accepts cookie and consent banners like a visitor and removes more than 60 known consent platforms, newsletter popups, and chat widgets before capture; each of those steps can be turned off. Bot checks, blank pages, failed loads, timeouts, and cache hits are not billed, and responses identify the page verdict and billing status in headers. An MCP server provides take_screenshot, get_page_info, and capture_pdf for AI agents and MCP clients. The free plan includes 1,000 shots a month without a card; paid plans start at $5 for 3,000 shots. All features are on every plan.
Keep the API key on the server and pass the requested URL. See the ScreenshotNeo API documentation for available parameters and response details.

Frequently Asked Questions
Should an Express screenshot endpoint be public?
Only if you have deliberately designed it for public access. Otherwise, authenticate callers and set usage limits appropriate to your application.
Can I expose the provider’s API key in browser JavaScript?
No. Keep it in server-side configuration and have the Express route make the provider request.
Does every screenshot API return a screenshot URL?
No. Some return JSON containing a URL, while others return image bytes; implement against the provider’s documented response contract.
