To capture a page with Screenshotlayer from Node.js, send a GET request to its capture endpoint with your access key and the target URL, then save the image response as a file. Keep the key in an environment variable and configure Axios to treat a successful response as binary image data—not JSON. The example below uses the HTTPS endpoint; confirm that HTTPS is available on your plan and check Screenshotlayer’s current API documentation for parameter and response details.
Make a Screenshotlayer request with Axios
Install Axios if it is not already in your project:
npm install axiosSet your API key in the environment before running the script. For example, on macOS or Linux:
export SCREENSHOTLAYER_ACCESS_KEY="your_access_key"Then save this as screenshot.js:
const axios = require('axios');
const fs = require('node:fs/promises');
async function capture() {
const accessKey = process.env.SCREENSHOTLAYER_ACCESS_KEY;
if (!accessKey) {
throw new Error('Set SCREENSHOTLAYER_ACCESS_KEY before running this script.');
}
const endpoint = 'https://api.screenshotlayer.com/api/capture';
try {
const response = await axios.get(endpoint, {
params: {
access_key: accessKey,
url: 'https://example.com',
format: 'PNG'
},
responseType: 'arraybuffer',
timeout: 60000
});
const contentType = response.headers['content-type'] || '';
if (!contentType.toLowerCase().startsWith('image/')) {
const body = Buffer.from(response.data).toString('utf8');
throw new Error(`Expected an image response; received ${contentType || 'unknown content type'}: ${body}`);
}
await fs.writeFile('screenshot.png', Buffer.from(response.data));
console.log('Saved screenshot.png');
} catch (error) {
if (error.response) {
const contentType = error.response.headers?.['content-type'] || '';
const body = Buffer.from(error.response.data).toString('utf8');
console.error('Screenshotlayer returned HTTP', error.response.status, contentType, body);
} else {
console.error('Request failed:', error.message);
}
process.exitCode = 1;
}
}
capture();The code assumes a Node.js version with the built-in node:fs/promises module. It uses Axios’s arraybuffer response type so the image bytes can be written without text decoding. Axios error and response behavior can vary by Axios version; check the documentation for the version installed in your project and adjust error-body parsing if needed. Screenshotlayer’s official homepage and FAQ document the capture endpoint and image formats: Screenshotlayer and FAQ.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
What the request parameters do
The required inputs are the API access key and page URL. The homepage examples use access_key and url as query parameters. Axios’s params option encodes these into the GET request URL.
format: The FAQ identifies PNG as the default and says JPEG and GIF can also be requested. Set the desired output format using the currently documented parameter syntax before changing the output filename or downstream processing.viewport: The homepage shows viewport dimensions as a capture option. Use the current API documentation for its accepted format.fullpage: The homepage lists full-page capture as an option. Check its currently accepted values in the API documentation.width: The homepage example includes a width option for thumbnail sizing.- Other settings: The homepage lists custom headers, injected CSS, capture delay, caching, and export to AWS S3 or FTP. Exact parameter names and constraints should be confirmed in the live API documentation.
Screenshotlayer’s homepage examples show an HTTP endpoint, while its product page advertises HTTPS support for paid plans. The code uses HTTPS, but whether it works depends on the current plan and service terms. Review the current endpoint and plan details before relying on HTTPS.

Keep the API key out of source control
Screenshotlayer authenticates requests with a personal access key. Load it from an environment variable or a secrets manager, rather than embedding it in a committed JavaScript file. The key is included in the query string for this API, so avoid logging complete request URLs and take care when sharing error logs. Screenshotlayer’s terms state that users are responsible for keeping credentials secret: terms.
Handle image responses and API errors
A successful call returns image content, not a JSON object containing an image by default. The sample requests binary response data, checks the returned content type, and writes the bytes to a PNG file. If you ask for JPEG or GIF, save with a matching extension and verify the content type and current API parameter for that format.

HTTP errors are caught separately from failures that occur before a response arrives. When Screenshotlayer returns an error response, the example prints its status and response body. Do not assume every error body is JSON; it may be text or another format. The precise response envelope and error schema are not established here, so inspect the service’s current API documentation before building a parser around them.
Troubleshooting
- Missing-key error: Check that
SCREENSHOTLAYER_ACCESS_KEYis set in the same shell or process environment that starts Node.js. Do not paste the key into the source as a workaround. - Authentication failure: Confirm the key is current and belongs to the account you intend to use. Verify the spelling of
access_keyand avoid accidentally including whitespace in the environment variable. - HTTP endpoint or HTTPS failure: The homepage samples use HTTP, while HTTPS is advertised for paid plans. Confirm the endpoint scheme supported by your plan in the live documentation rather than silently downgrading a production integration.
- “Expected an image response”: The response may be an API error body, or the request may not have produced an image. Check the logged status, content type, body, URL, and key; consult the current API docs for the required parameters.
- Corrupt output: Make sure Axios is configured for binary data, and do not convert successful image bytes to a UTF-8 string. Use an extension consistent with the requested format.
- Timeout: The example sets a 60-second client timeout. A timeout means the client did not receive a response within that interval; it does not establish whether the service completed the capture. Choose a timeout appropriate to your application and handle retries carefully to avoid unintended repeat usage.
Plans, quotas, and usage costs
As advertised on Screenshotlayer’s pricing and signup pages on October 3, 2026, the plans list the following monthly allowances and prices. These are volatile service terms; check the current pages before selecting a plan. The official pricing page also advertises annual billing discounts.
