The reason why is that the completion of a task by a provider is not the same as accepting that task result by the destination. Most poor solver choices comes from picking based on headline price alone rather than workflow output needs. This comparison considers six providers based on the quality of task fit, delivery model, published prices, and ease of integration. It uses data from the current documentation of vendors. You will also get a secure API v2 integration pattern and a simple criterion of selecting token solving, browser-based solving and prevention. ## Key Takeaways - **Choose by task and delivery model.** A token API, a human-worker service, and a browser-integrated solver return different outputs and should not be compared as interchangeable products. - **2Captcha is no longer human-only.** Its current API documentation describes an AI-first system that sends difficult cases to verified human workers as fallback. - **A returned token is not proof of target acceptance.** The target can still reject an expired token, mismatched task, changed page state, or inconsistent session context. - **Compare current list prices on the same CAPTCHA type.** Do not rank providers by advertised speed, accuracy, or reliability without one controlled benchmark covering the full roster. - **Use solving only for the challenge layer.** When CAPTCHA is a symptom of broader bot detection, a managed fetch through Scrapfly Unblocker can be the more direct route to usable page content. **Get web scraping tips in your inbox**Trusted by 100K+ developers and 30K+ enterprises. Unsubscribe anytime. ## Which CAPTCHA Solving API Should You Choose in 2026? The right option is the provider that documents your exact challenge and returns the output your workflow needs. Price per 1,000 solves only matters once the task type and delivery model match. The table compares all six options on the two challenge types scrapers hit most often. | Provider | Delivery model | Documented fit | reCAPTCHA v2 list price | Turnstile list price | Main limitation | |---|---|---|---|---|---| | 2Captcha | AI-first, human fallback, token API | Broad token and puzzle tasks | EUR 0.99-2.80 / 1K | EUR 1.40 / 1K | Task fields and price vary by type | | CapSolver | Automatic API and extension | reCAPTCHA, Turnstile, AWS WAF, GeeTest, image | USD 0.80 / 1K | USD 1.20 / 1K | Pricing page narrower than marketing pages | | Anti-Captcha | Human workers, API and plugins | Human, custom, reCAPTCHA, Turnstile | USD 0.95-2.00 / 1K | USD 2.00 / 1K | Queue behavior is not a benchmark | | DeathByCaptcha | OCR plus human verification | Token, image, and audio tasks | USD 2.89 / 1K | USD 2.89 / 1K | Accuracy and timing are self-reported | | AZcaptcha | Token API and extension | Pay-as-you-go reCAPTCHA and Turnstile | USD 1.00 / 1K | USD 1.20 / 1K | Only pay-as-you-go rates are current | | Steel | Browser-integrated solving | Stateful browser sessions | USD 3.00 / 1K (Launch), USD 1.00 (Scale) | Same CAPTCHA meter | Browser time and proxy billed separately | *Public pricing checked September 2026. Currencies and task units differ between providers.* Notice that the table has no winner column. A cheap reCAPTCHA v2 rate is irrelevant if the provider does not document your challenge variant, and Steel's price is not directly comparable to the five token APIs. That last point is the most common source of confusion, so the next section separates the three kinds of output these products return. ## How Do Token APIs, Browser-Integrated Solvers, and Scrapfly Unblocker Differ? Token APIs return a challenge result, browser-integrated solvers work inside a live session, and Scrapfly Unblocker returns fetched page content after handling the access layer. They solve different jobs, so comparing them on price alone misleads. | Reader's job | Right layer | Output | Main boundary | |---|---|---|---| | Get a token for a documented challenge | Token API (2Captcha, CapSolver, Anti-Captcha, DeathByCaptcha, AZcaptcha) | Token or challenge answer | Target acceptance still happens in your workflow | | Keep detection and solving inside a browser | Steel CAPTCHA API | Session state and solve status | Browser, proxy, and solver usage are separate meters | | Retrieve a protected page without token plumbing | Scrapfly Unblocker or Web Scraping API | Page response or rendered content | Managed fetch path, not a token marketplace | With a token API, `ready` is a provider task state. It tells you the provider finished its work. It does not tell you the destination accepted the result and your code still has to submit the token in the right page context. Proxy requirements depend on the task. Some tasks are proxyless while others accept or require your own proxy. Do not assume every solve needs a residential IP or same-IP submission. Prevention belongs in this decision as a route choice. When a challenge appears because the target distrusts your TLS fingerprint, headers, or IP, fixing those signals can remove the challenge entirely.

Diagnose the failure first, then escalate from HTTP to a rendering API to stateful browser automation.](https://scrapfly.io/blog/posts/best-anti-bot-bypass-tools) Scrapfly sits in the third row as managed scraping and anti-blocking infrastructure. It is not a CAPTCHA solver vendor. Once you know which layer you need, the next step is comparing candidates inside that layer without trusting marketing numbers. ## How Should You Compare CAPTCHA Solving APIs Safely? Evaluate the providers on completions of one authorized task, not on their marketing or number of tokens issued. A token that is rejected by the destination is not valuable but costly. Identify three factors before evaluating any provider. - Specific task type, like reCAPTCHA v2 or Turnstile - Variant of the task, like invisible, enterprise, or proxyless - Desired result of your workflow, either token or full-page completion Choose two providers who support this task and perform this task for both providers using the same authorized example. Use identical client code, task parameters, network policy, and timeouts. Track these as separate events Compare CAPTCHA-solving providers by measuring the full workflow, not just returned results: create the task, receive the provider response, confirm the destination accepts it, and verify the workflow completes successfully.This is the step where most people make mistakes when they compare systems. When you do a benchmark, then measure the latency in end-to-end p50 and p95, accepted-result rate, and the cost per accepted completion. These figures are not provided here since they have not been gathered. Consider also what is being sent out from your environment. In a task, the URL of the page, site key, screenshots, cookies, user-agent, proxy credentials, or instructions for a third-party provider can be passed. Human-based service providers may give you more context information about the tasks than automated. When testing your own system, use official test keys or a vendor demo page. Do not continue solving when you are denied access. After adopting a strategy, the entries in the provider list below will give you an idea of which contenders to consider. ## Which CAPTCHA Solving API Fits Each Workflow? Each provider below fits a different workflow. The entries use the same format, covering delivery model, documented tasks, public price, one strength, and one limitation. Prices are the September 2026 list prices from the comparison table. ### 2Captcha for Broad Documented Task Coverage 2Captcha is suitable for groups requiring a single provider for a variety of challenges. Current documentation suggests an AI-first approach that passes on more complicated cases to human solvers as a second solution option. Previously existing descriptions of 2Captcha as a human-only solver are outdated due to contradicting documentation. List of documented solving tasks includes reCAPTCHA v2 and v3, Cloudflare Turnstile, Arkose Labs, GeeTest, AWS WAF, and image tasks. List is representative but not comprehensive. - **Price:** EUR 0.99-2.80 per 1,000 for reCAPTCHA v2, EUR 1.40 per 1,000 for Turnstile - **Strength:** unified JSON API v2 with `createTask` and `getTaskResult` endpoints for all task families - **Limitation:** you do task family-specific implementation and validation of the target manually ### CapSolver for Automatic Token API Workflows The CapSolver solution is appropriate for users who require an full automatic token API along with a browser extension as a secondary option. The solution’s official documentation discusses how to use the solution to solve reCAPTCHA, Turnstile, AWS WAF, GeeTest, and image recognition challenges. - **Price:** USD 0.80 per 1,000 reCAPTCHA v2 requests, USD 1.20 per 1,000 Turnstile - **Strength:** task-based API that uses a create-and-poll scheme, similar to the one of other token providers - **Weakness:** differences in details on the marketing pages and the dedicated pricing page may lead to discrepancies when budgeting There is no universal benchmark to compare speed, therefore no claim is made. ### Anti-Captcha for Human and Custom Tasks Anti-Captcha fits tasks that need human interpretation or custom instructions. It runs a human-worker model behind a task API and also offers browser plugins. Documented tasks include reCAPTCHA, Turnstile, and custom tasks. - **Price:** USD 0.95-2.00 per 1,000 for reCAPTCHA v2, USD 2.00 per 1,000 for Turnstile - **Strength:** custom tasks cover challenges that automated solvers do not document - **Limitation:** human queues add a separate processor and can expose more task context to third parties Queue behavior varies, so this entry makes no fixed completion-time or consistency claim. ### DeathByCaptcha for Hybrid and Existing Integrations The DeathByCaptcha solution will be suitable for those who have an integration set up already or wish to use their client libraries. It includes OCR and human verification and provides both API clients and browser extensions. Documented tasks include token, image, and audio challenges. - **Price:** USD 2.89 per 1,000 for reCAPTCHA and for Turnstile - **Strength:** well-established client solutions that minimize migration efforts for existing customers - **Limitation:** no accuracy and timing data obtained using a common method ### AZcaptcha for Straightforward Pay-As-You-Go Tasks AZcaptcha fits simple pay-as-you-go use on common token tasks. It offers an API and a browser extension. - **Price:** USD 1.00 per 1,000 for reCAPTCHA v2, USD 1.20 per 1,000 for Turnstile - **Strength:** a direct pay-as-you-go model on documented reCAPTCHA and Turnstile tasks - **Limitation:** current public evidence supports the per-task rates only, not the older subscription plan or success-rate figures earlier versions of this article cited ### Steel for Browser-Integrated CAPTCHA Handling Steel integrates into existing workflows running inside a cloud browser and requiring detection and solving to be done within that session. Steel’s CAPTCHA API returns the status of the page, which may include: `detected`, `validating`, `validation_failed`, `solving`, `solved`, `failed_to_detect`, and `failed_to_solve`. - **Price:** USD 3.00 for every 1,000 CAPTCHA solved using the Launch plan, USD 1.00 using the Scale plan - **Strength:** ability to define actions depending on failed validation or detection attempts - **Limitation:** CAPTCHA solves, browser minutes, and proxy minutes are billed separately, meaning solve price is not an equivalent to the five token APIs However, in case you have chosen a token API, read the next section about how to make a safe API request. ## How Do You Integrate 2Captcha API v2 Without Exposing Credentials? Pass the key in the body of the HTTPS JSON requests in API v2, manage provider/transport errors, time out after a fixed deadline, and treat the `ready` status as completion from the provider side only. The old way of passing keys via `in.php` and `res.php` exposed it in logs/proxies. Install the client first. shell ```shell pip install httpx==0.28.1 ``` The example below uses the documented `RecaptchaV2TaskProxyless` task against the 2Captcha reCAPTCHA v2 demo page. python ```python import os import time import httpx API_BASE = "https://api.2captcha.com" POLL_INTERVAL = 5 # seconds, the documented minimum between result checks DEADLINE = 180 # seconds before giving up on a task class SolverError(Exception): pass def call_api(client: httpx.Client, method: str, payload: dict) -> dict: """POST a JSON payload to an API v2 method and return a validated body.""" try: response = client.post(f"{API_BASE}/{method}", json=payload) response.raise_for_status() body = response.json() except httpx.HTTPError as exc: raise SolverError(f"{method}: transport error ({type(exc).__name__})") from None except ValueError: raise SolverError(f"{method}: response was not valid JSON") from None if not isinstance(body, dict): raise SolverError(f"{method}: expected a JSON object") if body.get("errorId", 1) != 0: code = body.get("errorCode", "UNKNOWN_ERROR") raise SolverError(f"{method}: {code} {body.get('errorDescription', '')}".strip()) return body def solve_recaptcha_v2(website_url: str, website_key: str) -> str: api_key = os.environ["TWOCAPTCHA_API_KEY"] task = { "type": "RecaptchaV2TaskProxyless", "websiteURL": website_url, "websiteKey": website_key, "isInvisible": False, } with httpx.Client(timeout=30) as client: created = call_api(client, "createTask", {"clientKey": api_key, "task": task}) task_id = created.get("taskId") if not task_id: raise SolverError("createTask: response had no taskId") deadline = time.monotonic() + DEADLINE while time.monotonic() < deadline: time.sleep(POLL_INTERVAL) result = call_api(client, "getTaskResult", {"clientKey": api_key, "taskId": task_id}) status = result.get("status") if status == "processing": continue if status != "ready": raise SolverError(f"getTaskResult: unexpected status {status!r}") token = (result.get("solution") or {}).get("gRecaptchaResponse") if not token: raise SolverError("getTaskResult: ready result had no gRecaptchaResponse") # "ready" means the provider finished, not that the target accepted it return token raise SolverError(f"task {task_id} not ready after {DEADLINE} seconds") if __name__ == "__main__": token = solve_recaptcha_v2( website_url="https://2captcha.com/demo/recaptcha-v2", website_key="6LfD3PIbAAAAAJs_eEHvoOl75_83eXSqpPSRFJ_u", ) print(f"Provider returned a token of {len(token)} characters") ``` Scrapfly #### Need to bypass anti-bot protection? Scrapfly's Unblocker handles Cloudflare, DataDome, and more — automatically. [Try Free →](https://scrapfly.io/register)The key comes from the `TWOCAPTCHA_API_KEY` environment variable and only ever travels in a POST body. Error messages carry the method name and provider error code, never the key or the request payload. `call_api` catches all exceptions that may occur prior to taking task state into account. These include HTTP errors, timeouts, response body not being JSON, not being an object, and non-zero `errorId` parameter. The provider-specific errors come back in terms of `errorCode` and `errorDescription`, which allows us to avoid retries on terminal conditions like invalid key and zero balance. The poll loop sleeps for five seconds between requests and operates until a certain deadline is reached. Only `processing` status causes further retries. Unknown status and `ready` with missing `gRecaptchaResponse` cause an error rather than successful completion. This function returns the token without printing anything. The `with` statement closes the HTTPX client in all possible cases of exiting from the function. This method returns the token without printing anything. The `with` construction will close the HTTPX client no matter what way out of this method. This is the source-validated provider API workflow. This code was tested on HTTPX 0.28.1 and proved that the error path of the provider appears to be clean enough when there is an invalid key. Submitting the token back into a page depends on the challenge and the page, so DOM injection is left out here. For more about that step for Playwright and Selenium, Check [5 Proven Ways to Bypass CAPTCHA in Python for 2026Captchas can ruin web scrapers but we don't have to teach our robots how to solve them - we can just get around it all!](https://scrapfly.io/blog/posts/how-to-bypass-captcha-web-scraping) Owning this plumbing is only worth it when you actually need the token, which leads to the alternative route. ## When Should You Use Scrapfly Unblocker Instead of a CAPTCHA Solver API? Use Scrapfly Unblocker when the job is retrieving protected page content without wiring up a separate challenge token flow. Use a solver API when your workflow specifically needs a challenge answer or token. The difference is in the output. A solver returns a task result that you still have to submit and validate. Scrapfly returns the fetched response or rendered page content. In the [Web Scraping API](https://scrapfly.io/products/web-scraping-api), Unblocker behavior is still enabled with the `asp=True` parameter. The [Unblocker documentation](https://scrapfly.io/docs/scrape-api/unblocker) covers its current limits and managed-fetch behavior. Neither route guarantees acceptance on every target. Unblocker removes token plumbing from your code, while a solver gives you direct control over the challenge step. Whichever route you pick, tokens will occasionally get rejected, so the next section covers how to diagnose that. ## Why Does a CAPTCHA Solver Return a Token That the Target Rejects? A solver can finish its task while the target rejects the result, because provider completion and destination validation are separate steps. Debug them separately, starting from the provider side. | Symptom | Check first | Safe next action | |---|---|---| | Task rejected immediately | API key, balance, task type, required fields, JSON shape | Fix the request before retrying | | Task stays in `processing` | Poll interval, timeout, provider status | Stop at the deadline and surface a timeout | | Provider returns an error | `errorId`, `errorCode`, and `errorDescription` | Handle the terminal error explicitly | | `ready` result has no token | Task-specific solution field | Treat it as malformed, not successful | | Target rejects the token | Task variant, page URL, site key, action, expiry, page state, session requirements | Recheck the task docs and change one variable at a time | The first four rows are provider problems, and the code example above already surfaces each one as an error. The final row is the difficult part. The tokens expire, so it is possible that the results you send a long time after their generation will be invalid. Also, a token generated for an incorrect page URL, site key, or variant (invisibility/checkbox) won’t work either. Page status plays a role here as well. If the page was refreshed and/or form was altered since the moment you read the site key, the token will become invalid. Proxy and session requirements are task-specific. Some tasks need a consistent IP or cookies between solving and submission, and others do not. Check the exact task documentation instead of applying one integration's same-IP rule to every challenge. To understand how to keep sessions consistent when a task does require it,check [The Complete Guide To Using Proxies For Web ScrapingIntroduction to proxy usage in web scraping. What types of proxies are there? How to evaluate proxy providers and avoid common issues.](https://scrapfly.io/blog/posts/introduction-to-proxies-in-web-scraping) And for Turnstile-specific mechanics, see [How to Bypass Cloudflare TurnstileLearn how Cloudflare Turnstile detects bots and 3 proven methods to bypass Turnstile challenges when web scraping.](https://scrapfly.io/blog/posts/how-to-bypass-cloudflare-turnstile) The FAQ below answers the setup questions that come up most often during that debugging. ## FAQ Do CAPTCHA Solving APIs Always Need Residential Proxies?No. Some tasks are proxyless, while others accept or require your own proxy or a consistent session context. Follow the exact task documentation for your challenge rather than rotating residential IPs by default. Adding a proxy the task does not need adds cost and another failure point without improving acceptance. Can Python, Node.js, Playwright, and Selenium Use the Same CAPTCHA API?Yes, because HTTP APIs are language-agnostic, but the browser handoff and target validation differ by framework. This article uses Python and HTTPX for the provider calls. Does a CAPTCHA API Accept the Same Payload for reCAPTCHA v2 and v3?No. Use the provider's task-specific schema. reCAPTCHA v2 and v3 have different task identifiers and parameters, and v3 adds fields such as the page action and minimum score. A request shape that works for v2 is not a drop-in payload for v3, which is why the example above stays on the documented v2 task. ## Which CAPTCHA Solving Route Should You Use? First, determine the specific challenge and the output you require before choosing the service provider. Afterward, consider the present market prices and the support for the task, and perform an accepted performance test if necessary. Employ the token API when the result from the challenge is required, use Steel if solving must happen within a browser session, and choose Scrapfly Unblocker if the desired output is behind a paywall. In the latter case, begin by referring to the [Scrapfly Unblocker documentation](https://scrapfly.io/docs/scrape-api/unblocker). ### Anti-Bot Bypass Bypass Cloudflare, DataDome, Akamai, and other anti-bot protections automatically.
