Web Unlocker FAQ
What are the benefits of Web Unlocker API?
Web Unlocker API is best for use cases that involve web scraping. Instead of manually dealing with CAPCHAs, blocks, and other restrictions, Web Unlocker does the unlocking for you, and does so at an extremely high success rate (typically 100%). All you need to do is send one request, and the Unlocker takes care of the rest including adapting to constantly changing site blocks.
Is Web Unlocker API a proxy?
Web Unlocker API uses Bright Data’s proxy infrastructure and has three major components that other premium proxies lack:
1. Request management: Web Unlocker uses retry logic and CAPTCHA-resolving to ensure a near 100% success rate.
2. Complete user emulation including:
3. Content verification: The data you collect is automatically validated using parameters such as request timing, data types, and response content to ensure you are collecting the highest quality information available.
Can I use Web Unlocker API to interact or navigate with a browser?
No, Web Unlocker API is not made for use on browsers or third party tools like Adspower, Puppeteer, Playwright, or Multilogin (MLA). If you need a solution that interacts with a browser, which also incorporates Bright Data’s unblocking tool Web Unlocker, check out our Scraping Browser solution.
Can I use Web Unlocker API without a monthly commitment?
Yes! Simply select the ‘Pay-As-You-Go’ plan at signup. Please note that the CPM is higher in the ‘Pay-As-You-Go’ plan, and you can switch plans at any stage.
Can Web Unlocker API bypass Akamai Bot Manager?
Yes. Web Unlocker API is specifically built to handle sophisticated bot protection systems including Akamai Bot Manager. Akamai is one of the most challenging anti-bot systems in use today, deployed across real estate, financial, and e-commerce sites. Web Unlocker handles it automatically by combining browser fingerprint emulation, intelligent IP rotation, TLS fingerprint management, and behavioral mimicry at the network, protocol, browser, and OS level. No additional configuration is required on your end.
Can Web Unlocker API bypass hCaptcha?
Yes. Web Unlocker API automatically detects and solves hCaptcha, including the image-based challenge variants commonly used on auction platforms, gaming sites, and real estate portals. hCaptcha solving is on by default and requires no setup. If a target page presents an hCaptcha challenge during your scraping session, Web Unlocker resolves it and returns the unlocked content transparently, without interrupting your pipeline.
Can Web Unlocker API bypass reCAPTCHA v3?
Yes. Web Unlocker API handles reCAPTCHA v3, including its invisible, score-based variant that never shows a visible challenge to the user. Because reCAPTCHA v3 evaluates behavioral signals rather than presenting a puzzle, bypassing it requires realistic user emulation at every layer: IP reputation, browser fingerprint, request timing, and header patterns. Web Unlocker applies all of these automatically, which is why it achieves a near 100% success rate even on sites using reCAPTCHA v3 as a silent gatekeeper.
Which anti-bot systems and CAPTCHAs does Web Unlocker API support?
Web Unlocker API supports a broad and continuously updated range of anti-bot systems and CAPTCHA types. Supported solvers include: Akamai Bot Manager, hCaptcha, reCAPTCHA, reCAPTCHA v2, reCAPTCHA v3, Cloudflare Turnstile, PerimeterX, DataDome, Kasada, Imperva, Arkose Labs, Arkose MatchKey, Shape Security, Distil Networks, BotD, CAPTCHA.bot, NoCaptcha, SecureAuth, AWS WAF CAPTCHA, GeeTest, Tencent CAPTCHA, FunCaptcha, KeyCaptcha, Yandex CAPTCHA, BotDetect, SimpleCaptcha, Altcha, Friendly Captcha, Click CAPTCHA, Puzzle CAPTCHA, Slider CAPTCHA, Rotate CAPTCHA, Checkbox CAPTCHA, 3D CAPTCHA, Math CAPTCHA, Image CAPTCHA, Audio CAPTCHA, Text CAPTCHA. Because anti-bot technology evolves constantly, Bright Data's engineering team continuously updates the unlocking logic so you do not need to maintain or update anything on your side. See the full CAPTCHA Solver page for the complete and up-to-date list.
