Kasada
Kasada is a bot mitigation platform used by Twitch, Kick, Nike and many more. Bypass Kasada protection with CaptchaSolv API.
What is Kasada?
Kasada is an enterprise-grade bot detection and mitigation platform that protects websites by intercepting requests and requiring clients to execute a proof-of-work JavaScript challenge (p.js / ips.js). The payload performs browser fingerprinting (canvas, WebGL, audio, hardware concurrency) and generates short-lived cryptographic tokens — x-kpsdk-ct, x-kpsdk-cd, and x-kpsdk-v — that must be sent as HTTP headers with every subsequent request. Kasada is deployed by major platforms including Twitch, Kick, Nike, PlayStation, and numerous streaming, ticketing, and e-commerce services worldwide. CaptchaSolv solves the Kasada challenge automatically using its proprietary engine, returning valid x-kpsdk tokens and a matching User-Agent within 3–7 seconds so your automation pipeline never stalls.

Solve Kasada Automatically with CaptchaSolv
CaptchaSolv provides a production-ready API for automated Kasada challenge solving. Send the target URL and the full pjs script URL (ips.js / p.js path) — our engine executes the proof-of-work payload in a real browser and returns valid x-kpsdk-ct, x-kpsdk-cd, and x-kpsdk-v tokens in 3–7 seconds. Every response also includes the matching User-Agent string required for session consistency. Use KasadaTaskProxyless (built-in proxies included) or KasadaTask (bring your own proxy) depending on whether the target site enforces IP-based geo-restrictions. CaptchaSolv works with all Kasada-protected websites — Twitch, Kick, Nike, PlayStation, streaming platforms, sneaker sites, ticketing services, and more. Built-in residential proxies spanning 90+ countries, automatic retries on failure, and 24/7 uptime monitoring mean you can integrate once and scale to millions of requests. The engine adapts to Kasada script version updates in real time, so your automation pipeline never breaks due to a Kasada update.
Frequently Asked Questions
How do I find the Kasada pjs URL?
Open your browser DevTools → Network tab and look for requests to a file ending in 'ips.js' or containing '/149e9513-…/2d206a39-…/' in the path. This is the Kasada payload script URL.
Do I need to use the same User-Agent?
Yes. Kasada tracks User-Agent consistency. Always use the userAgent returned in the solution for all subsequent requests to the protected site.
How long are Kasada tokens valid?
Kasada tokens are valid for a single session or a short time window of a few minutes. Solve fresh tokens as needed for each new session.
Which websites use Kasada protection?
Kasada is used by major platforms including Twitch, Kick, Nike, PlayStation, and various gaming, streaming, e-commerce, and ticketing services worldwide. It is commonly identified by the x-kpsdk-* headers in network requests.
What headers does the Kasada solution contain?
The solution returns x-kpsdk-ct, x-kpsdk-cd, x-kpsdk-v headers and a userAgent string. All four values must be included in your requests to the protected endpoint.
What is the Kasada p.js / ips.js script?
The Kasada p.js (also called ips.js) is the proprietary JavaScript payload that performs browser fingerprinting and proof-of-work computation on the client. Its URL typically contains two UUIDs in the path (e.g. /149e9513-.../2d206a39-.../p.js). You can find it in the Network tab of DevTools by filtering for '.js' requests on the protected page.
Can I bypass Kasada without a proxy?
Yes. Use KasadaTaskProxyless and CaptchaSolv will use its own high-quality residential proxies at no extra cost. This is the recommended option for most use cases. Use KasadaTask only if the target site restricts access based on IP geolocation and you need a specific country's IP.
How does Kasada bot detection work?
Kasada intercepts requests to protected endpoints and redirects clients to a challenge page that loads the p.js payload. This script performs browser fingerprinting (canvas, WebGL, fonts, hardware concurrency), proof-of-work computation, and behavioral analysis. It then generates signed cryptographic tokens (x-kpsdk-ct, x-kpsdk-cd) that expire quickly. CaptchaSolv solves the Kasada challenge automatically using its proprietary engine to produce valid tokens.
