Why NexCaptcha

Change one base URL.

Our REST surface follows the createTask / getTaskResult convention the whole category uses. For most providers, migration is a base URL and an API key, not a rewrite.

Before

const client = new Solver({

apiKey: process.env.SOLVER_KEY,

baseURL: "https://api.2captcha.com",

});

After

const client = new Solver({

apiKey: process.env.SOLVER_KEY,

baseURL: "https://api.nexcaptcha.net",

});

01Identical task type names — RecaptchaV2TaskProxyless, TurnstileTaskProxyless, GeeTestTaskProxyless.
02Identical auth: clientKey in the request body, no header juggling.
03Run both in parallel on a traffic split until you trust the numbers.

Coming from	API compatibility	What you change
2Captcha	Drop-in — change the base URL	Point your existing client at https://api.nexcaptcha.net/createTask and swap the API key — nothing else in the request body changes.
Anti-Captcha	Drop-in — change the base URL	Point your existing client at https://api.nexcaptcha.net/createTask and swap the clientKey value — the field name and the whole request envelope stay as they are.
CapMonster Cloud	Drop-in — change the base URL	Point your existing client at https://api.nexcaptcha.net/createTask and swap the clientKey value — the paths and the request envelope are identical.
CapSolver	Thin adapter — same concepts, different names	Point your existing client at https://api.nexcaptcha.net/createTask and swap the clientKey value; drop appId, which has no equivalent here.
DeathByCaptcha	Drop-in — change the base URL	Point your existing client at api.nexcaptcha.net and swap the API key — if you are on their 2Captcha or Antigate compatibility endpoint, that base URL constant is the whole migration.
NextCaptcha	Drop-in — change the base URL	Point your existing client at api.nexcaptcha.net and swap the API key — the request envelope, the field names and the response shape are already identical.
穿云API (Cloudbypass)	Bespoke API — a small shim is needed	Decide first whether you want the page or a token. A request you were sending to api.cloudbypass.com wants the page, and that is the Automation API. If you were only using x-cb-sitekey to obtain a Turnstile token, the Captcha Solving API's TurnstileTaskProxyless is less work: no proxy, no session partition, token returned directly.

Solve your first thousand on us.

Create a key, paste it into the sample above, and watch a real token come back. No card, no sales call.
