Partner content. Prepared by the CaptchaAI team.
Your residential proxy connects, and the scraper receives a page. The request looks successful — until the parser finds a verification screen instead of the product information it expected.
Changing the IP immediately is not always the answer. The scraper needs to distinguish a connection problem from a CAPTCHA, then handle the challenge without discarding the session required to continue.
Residential proxies and CaptchaAI address different parts of this workflow. This guide explains how to connect them, when the solver needs your proxy, and how to check that the collection task actually succeeded.
This type of workflow should only be used in owned, client-authorized, or contractually permitted environments.
What Do Residential Proxies and a CAPTCHA Solver Each Do?
A residential proxy changes the network exit used to access the target website. CaptchaAI processes supported CAPTCHA-solving requests.
For a collection workflow using PSB Proxy residential proxies, the application remains responsible for request scheduling, session management, parsing, and output validation.
The separation matters because neither a working proxy nor a returned CAPTCHA result proves that the expected data was collected.
Track these outcomes individually:
| Stage | Success condition |
|---|---|
| Connection | The request reaches the target through the intended proxy. |
| Challenge handling | The supported CAPTCHA task returns a usable result. |
| Website verification | The target accepts the submitted result or session. |
| Extraction | The parser finds and saves the expected records. |
Diagnose the Response Before Rotating the IP
A scraper should inspect more than the HTTP status code.
A response can contain a verification page instead of the intended content. Validate expected fields, page markers, or the structure required by the parser.
If the response is unexpected, classify it before acting:
- Connection or authentication failure.
- Rate-limit response.
- Supported CAPTCHA challenge.
- Login requirement.
- Changed page structure.
For a rate limit, follow the site's instructions and adjust the request schedule. For changed markup, inspect the parser. Submit a solving task only when the interruption is a supported CAPTCHA.
Decide Whether the Session Needs a Stable IP
Rotation is useful between independent collection tasks, but changing the exit during a verification sequence can break a workflow that requires IP consistency.
For that sequence, use an appropriate persistent connection or session option where the provider supports it. Obtain the current connection details and session settings from your PSB Proxy account.
Do not assume that identical gateway settings mean an identical exit IP. Test what the destination sees across multiple requests.
Keep the country and session behavior consistent with the intended collection task, and avoid rotating between receiving a challenge and applying its result.

Know When to Pass the Proxy to CaptchaAI
The requirements differ by CAPTCHA method.
Cloudflare Challenge requires matching exit IPs, together with the returned clearance cookie and User-Agent.
For other supported methods, supply a proxy when the website or integration requires it. Proxy parameters are not a universal requirement.
CaptchaAI does not support reCAPTCHA v3 solving with a user-supplied proxy. A scraper may have its own proxy connection, but that proxy should not be included in the v3 solving task.
Before sending proxy-enabled tasks, sign in to CaptchaAI and activate Proxy in Account Configuration. Follow the method-specific documentation as well as the Using Proxies guide.
Build the Collection Workflow Step by Step
1. Verify the PSB Proxy Connection
Copy the host, port, authentication details, and protocol from your account.
Test them in the same HTTP client or browser environment that will run the scraper. Confirm access to the permitted target and the expected exit location.
2. Create the Session
Keep the relevant cookies, browser context, and connection available for the task.
If IP consistency is required, verify that the session holds the same exit throughout the operation.
3. Detect and Identify the CAPTCHA
Collect the inputs required by the corresponding CaptchaAI method.
Do not assume every challenge requires a site key or returns the same response format. reCAPTCHA, image CAPTCHA, and Cloudflare Challenge integrations differ.
4. Submit the Supported Task
Where required, add the documented proxy and proxytype parameters.
For username/password authentication, the documented proxy format is:
login:password@HOST:PORT
Use placeholders in shared examples and keep real credentials out of source control and logs.
5. Apply the Result and Validate the Data
Apply the result according to the method and website integration.
For Cloudflare Challenge, the follow-up website request must retain the matching exit IP and returned User-Agent when using the clearance cookie.
Check for the expected records before sending the response to the parser. Do not save verification-page text as though it were collected product data.
Test the Integration with 50 Free Threads

PSB Proxy users can get 50 free CaptchaAI threads for 3 days, with unlimited CAPTCHA solves within the trial's 50-thread capacity.
Send PSBProxy50 to @AskCaptchaAI on Telegram to request activation.
Start with a small representative collection task. Test session continuity, supported challenge handling, and extraction accuracy before increasing concurrency.
Example: A Product-Monitoring Task Meets a Challenge
Imagine a permitted monitoring job collecting prices from several catalogue pages.
One page returns the expected product data. The next returns a supported verification challenge.
Instead of discarding the whole batch, the application pauses the affected page, retains its session, and submits the appropriate CaptchaAI task. Where the method requires proxy matching, it supplies the intended connection.
After retrieving and applying the result, it requests the page again and checks for the expected product fields.
If validation succeeds, the page is parsed and saved. If it fails, the task is recorded for a bounded retry or investigation. Unaffected pages do not need to be restarted.
This is an illustrative workflow, not a performance benchmark. Its purpose is to make the recovery behavior explicit.
Scale According to Completed Records
All CaptchaAI subscription plans include unlimited solves within their selected thread capacity, without a fixed daily or monthly solve quota.
Threads control simultaneous solving tasks. If every thread is occupied, the application should queue additional work rather than repeatedly submitting requests.
More threads do not automatically produce more useful data. Browser resources, proxy capacity, request limits, parsing, and storage can become bottlenecks.
Measure:
- Valid records saved.
- Unresolved collection tasks.
- Time spent waiting for solving capacity.
- Challenge frequency.
- Proxy-related failures.
- Duplicate or incomplete records.
Increase concurrency gradually and observe whether valid output improves.
Troubleshoot the Failing Stage
| Problem | What to investigate |
|---|---|
| Proxy authentication fails | Credentials, protocol, and any allowlisting requirements. |
| The exit changes during verification | Rotation mode and session configuration. |
| A solution is returned but the page stays blocked | Result application, validity, and required session consistency. |
| Cloudflare Challenge repeats | Exit IP, returned User-Agent, and clearance-cookie handling. |
ERROR_NO_SLOT_AVAILABLE appears |
Active solving capacity and application queueing. |
| The scraper saves empty records | Response validation and parser assumptions. |
A repeated challenge is not proof that the proxy is the only cause. Inspect the full sequence before replacing the connection or submitting another solve.
