A ScreenshotAPI.net 403 does not point to one universal problem. Check the response’s specific error code and message first: screenshots_limit_reached and trial_expired are account or plan issues, while ERR_CONNECTION_REFUSED points to a connection problem involving the target site or network. Fix the matching cause rather than changing settings at random.
1. Read the error code before changing anything
ScreenshotAPI.net documents several different conditions with HTTP status 403. The status alone does not tell you whether to change your plan, check your trial, or investigate access to the target website. Find the exact code and message in the API response or the error shown by your integration. See the official error reference.
| Error code | What it indicates | First action |
|---|---|---|
screenshots_limit_reached |
Your usage quota has been exceeded. | Check account usage and plan quota; upgrade if you need more capacity. |
trial_expired |
The trial has expired. | Check account and trial status, then upgrade or restore an eligible account. |
ERR_CONNECTION_REFUSED |
The connection to the target was refused; possible causes include target availability, network problems, or a firewall. | Check that the target is reachable and investigate network or firewall restrictions. |
These are the error meanings ScreenshotAPI.net documents; they do not independently establish the root cause of a particular failed capture. If the code is absent or the message is ambiguous, retain the full response and check the target’s availability before assuming the site blocked the capture.
2. Fix account and quota errors
screenshots_limit_reached: quota exceeded
- Check the usage shown in your ScreenshotAPI.net account and compare it with your plan’s screenshot quota.
- If you have reached the quota and need more captures, follow the provider’s plan upgrade path. Its Help page says upgrading increases the screenshot quota.
- Retry after confirming the account’s quota or plan change is active.
Changing the target URL, headers, or proxy is not a remedy for an exhausted account quota.

trial_expired: trial no longer eligible
- Check whether the account’s trial has expired and whether the request is using the account you expect.
- Follow the error reference’s direction to upgrade to continue, or otherwise restore an eligible account.
- Retry once the account status is resolved.
Request-context settings cannot renew an expired trial.
3. Troubleshoot ERR_CONNECTION_REFUSED
This code is distinct from a quota or trial error: ScreenshotAPI.net describes it as a refused connection to the target. Investigate reachability and network conditions before treating it as a billing issue.

- Check target availability. Open the exact URL in a normal browser and confirm that the site is responding. Check for a typo, a temporary outage, or a page that is only available from a particular network or region.
- Check network restrictions. If the target is reachable for you but not through the API, consider whether a firewall or another network restriction could be refusing the connection.
- Verify the URL and request. Confirm that the URL points to the intended page and uses HTTPS, as described below.
- Test relevant request options one at a time. ScreenshotAPI.net documents custom headers, user-agent, and proxy settings. These can change request context or routing, but are conditional troubleshooting options—not guaranteed ways to make a refused or restricted page capturable.
The provider’s Browser Environment Emulation documentation describes headers, user-agent, and proxy options. Its proxy documentation describes routing through another IP for some network restrictions or regional content. Neither description guarantees a fix for a particular refusal or permission to access a restricted site. Do not use these settings to evade a site’s access policies.
4. Check the API request itself
Before attributing a failure to the target site, make sure the ScreenshotAPI.net request is constructed correctly. The documented v3 render endpoint takes a token and a target url. Use the parameter names and endpoint specified in the render documentation.

- Confirm the API token is present and is the intended token.
- Confirm the target URL parameter is named
url, not omitted or misspelled. ScreenshotAPI.net’s Help page identifies a missing or misnamed URL parameter as a request problem. - Pass a complete URL beginning with
https://, as the Help page advises. - Keep the exact response code and message when retrying so you can tell whether the failure changed.
A malformed or incomplete request should be corrected, but it does not explain an explicit quota error or prove that a connection refusal is caused by the request.
5. Test headers, user-agent, or proxy carefully
If the request is valid, the account is eligible, and the target is reachable, you can test the documented request-context controls when they are relevant:

- Please Note: To reach 10Gbps speed, keep the cable under 3.3 ft. For USB A Male to USB C adapters, try flipping the USB C connector. USB C Male to USB A adapters support bidirectional 10Gbps transfer within 3.3 ft
- Headers: Use a custom header only when the target needs it or you have a specific reason to test how it responds to different request headers.
- User-agent: A different user-agent can simulate a browser or device identity, but it does not guarantee acceptance by the target.
- Proxy: A proxy changes request routing and may be relevant to regional access or some network restrictions. It is not a universal solution to firewalls, bot checks, or site policies.
Change one setting per attempt and compare the returned code and message. This helps distinguish a meaningful change from an unrelated retry. Use only authorized access and follow the target site’s terms and restrictions.

ScreenshotNeo is an alternative to try first when your need is a screenshot API rather than a fix for a ScreenshotAPI.net account error. Its stated differences include removing known consent banners, newsletter popups, and chat widgets before capture, and billing only clean shots; responses identify the page verdict and billing status. It also provides an MCP server for AI agents. It cannot be assumed to overcome a target site’s access restrictions.

Make one GET request with your ScreenshotNeo API key and target URL. The following cURL command saves a WebP screenshot of Stripe:

Frequently Asked Questions
Does every ScreenshotAPI.net 403 mean the target website blocked the screenshot?
No. ScreenshotAPI.net also uses 403 for quota and expired-trial errors. Read the specific error code and message to distinguish those from a target connection refusal.
Will changing the user-agent or using a proxy always fix ERR_CONNECTION_REFUSED?
No. ScreenshotAPI.net documents these as request-context and routing options, not guaranteed fixes. The target, network, or firewall may still refuse the connection.
