NopeCHA-compatible API

Cheaper captcha recognition. Switch by changing one URL.

Solvecha answers reCAPTCHA grids, text captchas, GeeTest sliders and FunCAPTCHA through the same API you already use. Replace the base URL. Keep the rest of your code.

What this test is, and is not

One public demo page, one data-center IP, two days in October 2026. It shows how often each model got a token there. A random-answer control got a token on 0 % of challenges. It does not show answer times, and it does not cover other sites, IPs or captcha settings. We publish a speed comparison only after an end-to-end measurement through the public API.

Migration

Change the base URL. That is the migration.

Endpoints, request fields, response shapes and error codes follow the NopeCHA recognition API. Your polling loop, your retry logic and your SDK stay as they are.

  • Same /v1/recognition/<type> paths and the legacy root path
  • Key as key field, Bearer or Basic header, or ?key=
  • Same error codes and the same polling pattern

Text captcha

An image with distorted letters and digits. The answer is the text.

How it works

Three calls, no SDK needed

  1. 1

    Get a key

    Create an account and copy your API key from the dashboard.

  2. 2

    Send the image

    POST the base64 image and the task text. You get a job id back at once.

  3. 3

    Poll for the answer

    GET with the id once a second. Error 14 means: not ready yet. Then the answer arrives.
