Supported CAPTCHA and anti-bot challenge types

Choose the challenge type your authorized test needs, then use the same REST API to create and track the task. SolveHub covers token-based challenges such as Cloudflare Turnstile, cookie-based protections such as DataDome. Each type has its own guide with required fields, a cURL example, result format and common errors.

Availability varies by type. Check live status and per-task pricing before you send a request.

• Cloudflare Turnstile Create authorized Cloudflare Turnstile tasks with the SolveHub API: send websiteURL and websiteKey, poll the task and receive a response token.
• Cloudflare Interstitial Pass the Cloudflare challenge page with the SolveHub API and reuse the clearance cookie with the returned user agent and same proxy. Fields, cURL, errors.
• PerimeterX / HUMAN Solve PerimeterX / HUMAN with the SolveHub API: app ID, target site, proxy and browser cookies, plus how to reuse the returned cookies.
• DataDome Solve authorized DataDome challenges with the SolveHub API: submit the challenge URL and proxy, then reuse the datadome cookie with the same IP and user agent.

How the CAPTCHA Solver API Works

Use one REST workflow across supported challenge types. Set up your API key, create a task, then poll the same task until you have a result.

1. Get an API key Register and verify your email. Activate self-service when available, or bind a key issued by SolveHub. Add funds using the options shown in your console.
2. Create a task Send the challenge type and its required fields to POST /v1/tasks. Include an Idempotency-Key, and reuse the same key and request body if you need to retry.
3. Poll and use the result Request GET /v1/tasks/{taskId} about every 2–3 seconds. When the task completes, read the returned token, cookies or recognized text and use it in your authorized test workflow. If the task enters an uncertain state, keep checking the same taskId rather than creating a new task.

  -H 'Idempotency-Key: order-12345' \
  -d '{"type":"turnstile","task":{"websiteURL":"https://example.com","websiteKey":"SITE_KEY"}}'

Why Choose SolveHub for Authorized CAPTCHA Testing?

• Pay for completed tasks See the task price when you create it. SolveHub charges only when a task completes successfully; failed or cancelled tasks release the reserved amount.
• Retry without duplicate tasks Send an Idempotency-Key with each create request. Reuse the same key and request body after a timeout, and use traceId and X-Request-ID to investigate issues.
• Check availability and prices live Read GET /v1/prices for current public availability and per-task prices. If your key has negotiated rates, GET /v1/me/prices shows the prices that apply to you.
• Manage usage in one console Manage API keys, review usage and spending, configure task webhooks, and open support tickets. The console is available in English, Chinese and Japanese.

A CAPTCHA Solving Service for Authorized QA

SolveHub is a hosted solving service behind one REST endpoint. You send the challenge parameters for a page you are authorized to test, poll the task, and receive the token, cookie or text to feed back into your own workflow.

• Built for authorized testing QA automation, regression checks and browser integration on sites and workflows you have permission to test — not general bypass tooling.
• One REST endpoint The same create-and-poll flow covers every supported type; only the task fields differ between challenges.
• Charged per completed task The price is fixed at creation and only charged when a task completes; failures and cancellations release the reserved amount.
• Official test keys first Testing your own Turnstile or FunCaptcha widget? Cloudflare and Arkose test keys are free and deterministic; use a paid task only for a real challenge flow.

Frequently Asked Questions

Which challenges does the SolveHub CAPTCHA solver API support?

SolveHub supports Cloudflare Turnstile and Interstitial, DataDome, Akamai Bot Manager, PerimeterX / HUMAN, Imperva / Incapsula, AWS WAF, Alibaba Cloud CAPTCHA 2.0, Arkose Labs FunCaptcha, reCAPTCHA and GeeTest. Check GET /v1/prices for each type's current availability.

How is SolveHub billed?

Prices are listed per task in USD. The price is fixed when you create a task, and the task is charged only if it completes successfully. Failed or cancelled tasks release the reserved amount.

Do I need an SDK?

No. The API uses HTTPS and JSON. Create a task with POST /v1/tasks, then poll GET /v1/tasks/{taskId}. You can use any language with an HTTP client; the documentation includes cURL and Python examples.

Do I need to provide a proxy?

It depends on the challenge type. Cookie-based protections such as DataDome, Akamai, PerimeterX and Imperva usually need your proxy so the returned cookies match the IP you will use. Turnstile does not require one.

What happens if a solving route goes down?

For types with more than one solving route, such as Arkose FunCaptcha, SolveHub watches each route per CAPTCHA type. After 5 consecutive failures, new tasks switch to the backup route automatically and move back once the main route recovers. The API, request fields and pricing stay the same, and tasks that already started stay on their route.

How long does a task take?

Processing limits vary by type, with a soft window of about 90–180 seconds. If a task enters an uncertain state, continue polling the same taskId instead of creating a new task.

How do I get an API key?

Register and verify your email. Activate self-service when available to receive a key, or bind a key issued by SolveHub. You can manage key permissions and expiry in the console.
