Take a screenshot of a website in Python
Save a full-page PNG of any website, in Python 3.9+ with requests. Every program on this page runs as it stands — each one was run against a stub of the API before it was published.

TL;DR
To take a screenshot of a website in Python, POST its URL to https://urlpipe.dev/screenshot with sync set to true, decode the Base64 body with base64.b64decode and write the bytes to a .png file. It is a full-page capture from real Chrome for 1 credit; leave sync out and the result goes to your webhook instead.
Free plan, no credit card. 1,000 credits a month.
One POST to /screenshot loads the page in real Chrome, scrolls it top to bottom so lazy images load, and captures the whole document — not just the fold. The image comes back Base64-encoded in a text/plain body, so the Python work is two lines: decode it with base64.b64decode and write the bytes.
The request below also sets page_options.block_cookie_banners, because a consent dialog over the page is the most common reason a screenshot is useless. Every other knob — viewport, device scale, JPEG or WebP, one element by selector, dark mode — goes in screenshot_options.
Setup
Before you start
One dependency, requests. Put your API key in the environment so it never lands in the file.
python3 -m pip install requests
export URLPIPE_API_KEY="your_api_key"
The request
Save a screenshot as a PNG file
"sync": True holds the connection open until the result is ready and answers with it. Pass timeout= every time: requests has no default, and a page that never finishes loading would otherwise hang your process. The body is the image as Base64 text, so res.text goes through base64.b64decode before it is written in binary mode.
import base64
import os
import requests
res = requests.post(
"https://urlpipe.dev/screenshot",
headers={"Authorization": f"Bearer {os.environ['URLPIPE_API_KEY']}"},
json={"url": "https://example.com", "page_options": {"block_cookie_banners": True}, "sync": True},
# requests waits forever unless told otherwise; a sync call can take up to 60 s.
timeout=90,
)
res.raise_for_status()
png = base64.b64decode(res.text)
with open("screenshot.png", "wb") as f:
f.write(png)
print(f"Saved screenshot.png ({len(png)} bytes)")
Run it: python3 screenshot.py
Async
The async variant: a token, a webhook and a poll
Leave out sync and the answer is a token, straight away. for … else is the idiom for "ran out of attempts": the else runs only when the loop never hit break.
import base64
import os
import time
import requests
API = "https://urlpipe.dev"
HEADERS = {"Authorization": f"Bearer {os.environ['URLPIPE_API_KEY']}"}
# No "sync": the request is accepted at once and the work carries on without you.
res = requests.post(
f"{API}/screenshot",
headers=HEADERS,
json={
"url": "https://example.com",
"page_options": {"block_cookie_banners": True},
"report_to": "https://your-app.com/webhooks/urlpipe",
"labels": {"customer": "acme"},
},
timeout=30,
)
res.raise_for_status()
token = res.json()["token"]
print(f"Accepted {token}")
# The result is POSTed to report_to when it is ready. Polling by token is the
# other way to collect it: no endpoint needed, and a backup for the webhook.
for _ in range(60):
res = requests.get(f"{API}/result/{token}", headers=HEADERS, timeout=30)
if res.status_code != 202: # 202 means still processing
break
time.sleep(2)
else:
raise SystemExit("Still processing after two minutes; try the token again later.")
if res.status_code == 422:
raise SystemExit(f"The analysis failed: {res.json()['error']}")
if res.status_code == 410:
raise SystemExit("The result is past the 30-day window; send the request again.")
res.raise_for_status()
png = base64.b64decode(res.text)
with open("screenshot.png", "wb") as f:
f.write(png)
print(f"Saved screenshot.png ({len(png)} bytes)")
Run it: python3 screenshot_async.py
Errors
Handle errors and retries
raise_for_status() is fine for a script; a service wants to tell the failures apart. Check the status before calling res.json() — a 401 body is not JSON. sys.exit(message) prints to stderr and exits 1.
import base64
import os
import sys
import time
import requests
API_KEY = os.environ["URLPIPE_API_KEY"]
class URLpipeError(Exception):
pass
def urlpipe(path, payload, attempts=5):
"""POST a sync request and return the response, or raise URLpipeError."""
for attempt in range(attempts):
res = requests.post(
f"https://urlpipe.dev{path}",
headers={"Authorization": f"Bearer {API_KEY}"},
json={**payload, "sync": True},
timeout=90,
)
if res.status_code == 200:
return res
if res.status_code == 401:
raise URLpipeError("401: the API key is missing or wrong. Check URLPIPE_API_KEY.")
try:
body = res.json()
except ValueError:
body = {}
code = body.get("error", "")
detail = f"{code}: {body['message']}" if body.get("message") else code
if res.status_code == 429 and code == "rate_limited":
# Sending too fast: Retry-After says how long the window has left.
time.sleep(int(res.headers.get("Retry-After", 1)))
elif res.status_code == 429 and code == "concurrency_limit":
# Every parallel slot on your plan is busy with your own requests.
time.sleep(2**attempt)
elif res.status_code == 504:
# Still running on our side; the token collects it from GET /result/:token.
raise URLpipeError(f"504 processing_timeout: collect it later with token {body['token']}")
else:
# 403 email_unverified, 422 (a bad parameter, or a page that would not load),
# 429 quota_exceeded: sending the same request again gets the same answer.
raise URLpipeError(f"{res.status_code}: {detail}")
raise URLpipeError(f"429: still refused after {attempts} attempts")
try:
res = urlpipe("/screenshot", {"url": "https://example.com", "page_options": {"block_cookie_banners": True}})
except URLpipeError as error:
sys.exit(f"URLpipe: {error}")
except requests.RequestException as error:
sys.exit(f"Network error: {error}")
png = base64.b64decode(res.text)
with open("screenshot.png", "wb") as f:
f.write(png)
print(f"Saved screenshot.png ({len(png)} bytes)")
Run it: python3 screenshot_errors.py
Details
What to know about /screenshot
- The default viewport is 1350 × 797 and the capture follows the page down to 16,384 px; a taller page is cut there.
- Every response carries an
X-Result-Urlheader: a link to the same image that needs no API key and stays valid for 30 days. Often you can store that link instead of the file. - PNG is the default;
"format": "jpeg"or"webp"inscreenshot_optionsmakes a long page far smaller. - It captures images, not PDFs, and it does not record video.
- A screenshot of the same URL with the same options is served from the cache for 7 days by default, free. Set
max_ageto refresh sooner.
