What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
You can capture a list of URLs with ScreenshotMachine by looping through the list and making one API request per page. Its official API guide documents a single url parameter per request—not a documented multi-URL batch endpoint—so this is client-side batch automation. The example below saves each successful image separately and logs errors by URL.
What “batch” means with ScreenshotMachine
ScreenshotMachine’s API accepts a page URL in each HTTP GET request to https://api.screenshotmachine.com. The official guide does not document one request that accepts multiple target URLs. A script can still process many pages: read a URL list, send a separate request for each URL, and save each response to a distinct file. This approach does not establish a maximum list size, supported parallelism, or a rate limit; confirm current account-level limits with ScreenshotMachine before running a large job.

Prepare the URL list and output settings
Save one complete URL per line in a text file, for example urls.txt. The API needs your account key and the target url. The example uses Python’s HTTP library to encode query parameters, checks ScreenshotMachine’s documented X-Screenshotmachine-Response error header, and writes successful responses to indexed filenames.

1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitchesThe API defaults to a 120×90 JPG. Set dimension and format explicitly when that is not what you need. The documented dimensions are width × height: width from 100 to 1920 pixels, height from 100 to 9999 pixels, or full for a full-length page. Documented output formats are JPG, PNG, and GIF.

Run a sequential batch in Python
Install the dependency with python -m pip install requests. Set your API key in an environment variable rather than putting a real key in source code, then save this as capture_urls.py beside urls.txt:
import os
from pathlib import Path
import requests
API_KEY = os.environ.get("SCREENSHOTMACHINE_KEY")
if not API_KEY:
raise SystemExit("Set the SCREENSHOTMACHINE_KEY environment variable first.")
api = "https://api.screenshotmachine.com"
output_dir = Path("screenshots")
output_dir.mkdir(exist_ok=True)
urls = [line.strip() for line in Path("urls.txt").read_text(encoding="utf-8").splitlines()
if line.strip() and not line.lstrip().startswith("#")]
for index, url in enumerate(urls, start=1):
params = {
"key": API_KEY,
"url": url,
"dimension": "1024xfull",
"format": "png",
}
try:
response = requests.get(api, params=params, timeout=120)
api_error = response.headers.get("X-Screenshotmachine-Response")
if api_error:
print(f"FAILED {url}: {api_error}")
continue
response.raise_for_status()
filename = output_dir / f"shot-{index:04d}.png"
filename.write_bytes(response.content)
print(f"SAVED {url} -> {filename}")
except requests.RequestException as exc:
print(f"FAILED {url}: {exc}")For macOS or Linux, set the key and run the script with:

export SCREENSHOTMACHINE_KEY='your_key_here'
python capture_urls.pyIn PowerShell, use $env:SCREENSHOTMACHINE_KEY='your_key_here' before python .capture_urls.py. Replace the example dimensions or format if needed. The output folder contains files such as shot-0001.png; the printed log maps each index to its source URL. This implementation sends requests sequentially and is based on the documented one-URL request pattern; it is not a claim that ScreenshotMachine provides a batch endpoint or that a particular throughput is supported.

Useful capture parameters
Pass only the options needed for the pages in your list. The guide documents these optional parameters:

Compatible with Mac OS X 10.7 and higher / Windows 7, 8, 10 & 11 / Android 4.0 or higher / Linux 2.6.24 / Chrome OS 29.0.1547 / Ubuntu Version 10.04 or above. Not compatible with XBOX/PS4/PS5.
- 【Built-in Noise-Cancelling Microphone】The built-in noise-canceling microphone reduces ambient noise to enhance the sound quality of your video. Great for Zoom / Facetime / Video Calling / OBS / Twitch / Facebook / YouTube / Conferencing / Gaming / Streaming / Recording / Online School.

It's perfect to help provide security and peace of mind to anyone, from individuals to large companies. 【Note:】Please contact our support for firmware update if you have noticed any audio delays.
- 【Wide Compatibility】Works with USB 2.0/3.0, no additional drivers required. Ready to use in approximately one minute or less on any compatible device. Compatible with Mac OS X 10.7 and higher / Windows 7, 10 & 11, Pro / Android 4.0 or higher / Linux 2.6.24 / Chrome OS 29.0.1547 / Ubuntu Version 10.04 or above. Not compatible with XBOX/PS4/PS5.
device: choose a device rendering preset.cacheLimit: set the cache policy.delay: wait for a specified period before capture.zoom: change the page scale.click: activate an element selected with CSS before capture.cookies: provide semicolon-separated name/value pairs; percent-encode reserved characters.accept-languageanduser-agent: customize request headers used for page rendering.selector: capture a selected DOM element rather than the whole page.crop: capture a pixel rectangle.
ScreenshotMachine recommends percent-encoding the target URL. A standard HTTP client such as Python Requests encodes query parameters in the request URL; do not manually concatenate a raw URL containing characters such as & into the query string. For parameters such as cookies, ensure reserved characters are encoded as the API requires. The service’s API guide describes the available options and their syntax.
cURL equivalent for one URL
For a quick individual request, cURL can encode the page URL as a query parameter. Repeat this call with a different URL and output filename for each page; a shell loop can automate that repetition, but account limits should be confirmed before increasing throughput.

-o shot.pngFor client-side calls embedded in public HTML, ScreenshotMachine’s guide describes a hash safeguard: an MD5 value formed from the URL and configured secret phrase. When a secret phrase is configured, requests with a missing or incorrect hash are ignored. Do not expose an API key or secret phrase in public code; use a server-side script for batch jobs.

Check errors and billing before scaling up
A response may contain an error image rather than a usable screenshot. Check the X-Screenshotmachine-Response header and record failures against the corresponding URL. The API guide lists error codes including invalid_hash, invalid_key, invalid_url, missing_key, missing_url, no_credits, invalid_selector, invalid_crop, and system_error.

ScreenshotMachine’s pricing page states that only new, fresh screenshots are charged and that reused cached screenshots are not billed during the stated 14-day period. It also says additional screenshot counts are rounded down in groups of 1,000, giving 999 or fewer additional captures as an example that does not incur another thousand-count charge. These are the vendor’s stated billing terms; check the current pricing page and account limits before scheduling a large run.
Troubleshooting
| Symptom or response | Likely cause | What to check |
|---|---|---|
missing_key or invalid_key |
The key was omitted, misspelled, or is not valid for the account. | Check that the environment variable is set and that the request parameter is named key. |
missing_url or invalid_url |
The URL is absent, malformed, or not encoded correctly. | Ensure each non-comment line in urls.txt is a complete URL and pass it through an HTTP client’s parameter encoder. |
invalid_hash |
A required hash is missing or does not match the URL and configured secret phrase. | For direct public-HTML calls, generate the hash as specified by the API guide; keep the secret phrase private. |
invalid_selector or invalid_crop |
A selector or crop value is malformed or does not match the page. | Test the option on one URL first, and remove it for pages with different markup or dimensions. |
no_credits |
The account has no available credits for a new screenshot. | Review account usage and the current pricing terms before retrying. |
system_error, timeout, or other request failure |
The service reported an error, or the connection did not complete in time. | Keep the per-URL failure log, retry selectively, and avoid treating a returned error image as a successful capture. |
