• Images Base64 — JSON array of images encoded in base64. Required if 'Image URLs' is empty.
• Metadata (required) — JSON metadata including mandatory 'Grid' (e.g., 4x4, 3x3, 1x1) and either 'Task' or 'TaskDefinition' describing the captcha challenge.

a single JSON object representing the captcha solution response from CapMonster cloud service

The output JSON corresponds to the solution of the recaptcha click challenge. Either 'Image URLs' or 'Images Base64' must be provided, and 'Metadata' must include 'Grid' plus 'Task' or 'TaskDefinition'. Errors occur if validation fails or the API returns an error.
