+### TSPD
+
+<sup>[API method description.](https://2captcha.com/2captcha-api#tspd)</sup>
+
+Cookie-based method for automatic solving of TSPD captcha. Returns cookies that can be used to access the target page.
+
+Required parameters: `pageurl`, `tspdCookie`, `htmlPageBase64`, `proxy`, `proxytype`.
+
+**Important:** `tspdCookie` and `htmlPageBase64` are dynamic — extract them immediately before creating the task. A proxy with a static session and the same IP must be used at all stages.
+
+```js
+solver.tspd({
+    pageurl: "https://example.com/login",
+    tspdCookie: "TS386a400d029=082670...010245; TS386a400d078=082670...dbb3b0c",
+    htmlPageBase64: "PCFET0NUWVBFIGh0bWw+...",
+    userAgent: "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/138.0.0.0 Safari/537.36",
+    proxy: "login:password@1.2.3.4:8080",
+    proxytype: "HTTP"
+})
+.then((res) => {
+console.log(res);
+})
+.catch((err) => {
+console.log(err);
