Register a Cloudbypass API account — Sign Up Now

Register a Cloudbypass Proxy account — Sign Up Now

Cloudbypass uses a unified account system — registering once enables both API and Proxy access. Log in within 30 days and click the 🎁 Trial Activity button to claim free credits and traffic.

2.Test with the Code Generator

Enter your target URL in the Code Generator to test Cloudflare verification bypass.

V1 includes a built-in rotating IP pool — no proxy setup is required if accessible.
TV2 requires a fixed or time-based IP. When using Cloudbypass rotating IPs, set validity to at least 10 minutes.

For assistance, see the API documentation or contact Cloudbypass Support.

3.Integrate the Cloudbypass API

Integrate the Cloudbypass API into your application, complete debugging, and deploy to production.

4.Select a Pricing Plan

Choose a plan based on your usage — View Pricing

To bypass Cloudflare’s 5-second challenge, purchase a Points Plan.

For proxy traffic, select a Rotating Datacenter or Rotating Residential proxy plan.

Cloudflare bypass consumes points and may require proxy support. A proxy alone cannot bypass Cloudflare.

Cloudbypass Product FAQ

Find answers to common usage questions or contact our technical support team for assistance.

How are Cloudbypass API credits consumed?

Each successful API request consumes credits, while failed requests do not deduct any credits.
V1: Each successful request consumes 1 credit.
V2: Each successful request consumes 3 credits. One credit is used for the API request itself, and two additional credits are consumed during JavaScript polling. The session remains valid for 10 minutes. During this period, the same proxy and session parameters can be reused to avoid repeated Cloudflare verification. This means no additional credits are charged for subsequent requests within the same session window.

Cloudbypass API credits expire if not used within their validity period. Each recharge is calculated independently, and credits are consumed on a first-in, first-out basis.

Cloudbypass operates as a request-forwarding service. You submit an HTTP request to the Cloudbypass API, and the API executes the request on your behalf. This approach significantly reduces the likelihood of your traffic being identified as automated. The system focuses on preventing Cloudflare challenges from being triggered, allowing direct access to the target URL instead of programmatically interacting with challenge pages.

The Cloudbypass API is designed to be simple and developer-friendly. You only need to submit the HTTP request intended for the target website, and Cloudbypass will forward it exactly as provided.
You can use the online code generator to generate request examples in cURL, JavaScript, TypeScript, Java, Python, and more.
Cloudbypass API and Proxy integration examples are available here: View code examples

Cloudbypass V2 supports JavaScript rendering and polling, making it suitable for more advanced Cloudflare challenges.
V2 does not include a default proxy. You must use a Cloudbypass Proxy with V2.
V1 includes a built-in rotating proxy by default.

Session partitions are used to manage Cloudflare cookies and verified sessions. Once a session is successfully verified, the proxy IP, browser fingerprint, and related parameters must remain unchanged for 10 minutes. This prevents additional Cloudflare challenges from being triggered during the session.

Session partition values range from 0 to 999, allowing up to 1,000 concurrent session partitions per account. After a successful request, the proxy IP is locked to the session partition. Changing the partition value allows you to switch proxies. Each successful request refreshes the 10-minute session duration.

Start by testing your target URL using the code generator with Cloudbypass V1.
If V1 fails, switch to Cloudbypass V2 and configure your own proxy IP. A test proxy is available in the backend for validation. It is recommended to set the proxy extraction duration to more than 10 minutes.

All Cloudbypass API plans currently support up to 30 concurrent requests per second.

This error indicates that your Cloudbypass API account has no remaining credits.

You can purchase credits in the Cloudbypass API console: Cloudbypass API Console, or contact customer support to request test credits.

Error description:
This error occurs when the current session partition is already processing a Cloudflare challenge.

Common causes:
The same session partition is used concurrently by multiple threads.
Multiple users are operating on the same account and partition.
A previous request is still holding the verification lock.

Recommended solutions:
Wait for the lock to be released and retry the request.
Switch to a different session partition (range: 0–999).

Recommended actions:
1. Set the proxy IP extraction duration to at least 10 minutes.
2. Switch to proxy IPs from different countries or regions. Using IPs from the same region repeatedly may increase the risk of restriction.

These errors usually indicate that a proxy is required. You can use either API mode or Proxy mode to access Cloudbypass services. API mode is recommended for domestic users. Currently, only HTTP proxies are supported.

Browser automation tools such as Selenium and Puppeteer are not supported. Cloudbypass operates at the HTTP request level and simulates browser requests without launching a real browser.

Do you offer monthly subscription plans?

Cloudbypass does not use monthly subscriptions. All Cloudbypass Proxy services follow a traffic-based pricing model with no expiration. You can purchase traffic packages on demand, and unused bandwidth will never expire.

Cloudbypass Proxy supports multiple payment methods, including Alipay, USDT, and other supported options depending on your region.

For Cloudbypass Rotating Proxies, traffic usage is calculated based on the total volume of uploaded and downloaded data through the proxy connection.

IP geolocation results may vary depending on the detection database used. Please verify the proxy IP location using the official Cloudbypass IP check tool: http://ipinfo.cloudbypass.com .

Cloudbypass offers two core proxy networks: Rotating Residential Proxies and Rotating Datacenter Proxies. Both proxy types are designed for Cloudflare bypass scenarios and can be managed from a single unified platform.

Cloudbypass Proxy currently supports both HTTP and SOCKS5 proxy protocols, ensuring compatibility with most scraping tools, browsers, and automation frameworks.

Cloudbypass Proxy uses a traffic-based billing model for both rotating residential and datacenter proxies. All traffic packages do not expire. You may request a free trial to evaluate Cloudflare bypass performance before purchasing.

Direct connections from mainland China IP addresses are not supported. To use Cloudbypass Proxy services, you must deploy a global network environment, such as a server or VPS located in Hong Kong or other overseas regions.

Desktop users may connect via a global network accelerator, while mobile users can access through a router configured with a global network environment.

If you are unable to set up a compatible global network environment, please do not proceed with a purchase. Refunds are not available for unsupported direct connections.

Cloudbypass Help Center

Cloudbypass API FAQs cover credit rules, Version 2 updates, and concurrency limits. Overseas IP traffic is billed by data usage and supports multiple payment methods. Guides include Cloudflare bypass, HTTP API integration, global rotating proxies, fingerprint browsers, and multi-platform setup.

Cloudflare Bypass API Common Issues and Usage Rules
Cloudflare Bypass API: Common Issues & Usage Rules

Cloudbypass API credit rules: each successful request uses 1 credit, while Version 2 consumes 3 credits. Credits reset monthly and are separate from account balance. Version 2 supports JavaScript challenge polling and requires time-based proxy plans. Maximum concurrency is 30 requests per second. HTTP 403 or Access Denied errors typically require proxy configuration. The API is not compatible with Selenium or Puppeteer, but works with anti-detection browsers and data collection tools.

Data usage is calculated based on total upload and download traffic. The service provides rotating residential IPs and high-performance data center proxies, supporting HTTP and SOCKS5 protocols. A free trial is available after registration. For users in mainland China, usage requires a global network environment, as direct mainland IP access is not supported.
