# Grid Image

The **Grid Image** is used to solve CAPTCHAs that present an image divided into a grid of tiles, where users must select specific tiles based on a given instruction. commonly seen in reCAPTCHA v2 image challenges.
CaptchaAI analyzes the image and returns the indices of the tiles that should be clicked.

To solve this type of CAPTCHA:

1. **Prepare the image and instruction**:
  - The image must be the full reCAPTCHA grid (`3×3` or `4×4`).
  - The instruction is plain text describing what to select (e.g., `crosswalks`, `traffic lights`).
2. **Submit the task**:
  - For API V1: Send a POST request to `in.php` with `img_type=recaptcha` and the `grid_size` parameter.
→ See [API V1 – Grid CAPTCHA](/api/grid)
  - **API V2 COMING SOON**


1. **Receive a task ID** (e.g., `0123456789`) in the response.
2. **Wait 5 seconds**, then poll for the result:
  - In API V1: Use the `res.php` endpoint with your task ID.
→ See [API V1 – Get Result](/api/grid)
  - **API V2 COMING SOON**


1. **Process the response**:
  - If ready, you’ll receive a list of tile indices (numbered left-to-right, top-to-bottom):
Example: `[1, 3, 6, 9]` for a 3×3 grid.
  - If the status is `CAPCHA_NOT_READY`, wait 3 seconds and retry.
  - Handle any error codes as described in the [Error Handling](/pages/err_handling) section.
2. **Simulate clicks** on the indicated grid cells in your automation script.
3. **Repeat the process** if the CAPTCHA presents a new set of images after submission.
