 * A tool that leverages the JigsawStack VOCR API.

 * This tool allows you to recognize, describe, and retrieve data from images with great accuracy.
 *
 * To use this tool, ensure that the `JIGSAWSTACK_API_KEY` environment variable is set.
 * You can create a free API key at [JigsawStack](https://jigsawstack.com).
 *
 * @example
 * ```typescript
 * const tool = new JigsawStackVOCR({
 *   params: {
 *     prompt: "Describe the image in detail",
 *   },
 * });
 * const res = await tool.invoke("https://rogilvkqloanxtvjfrkm.supabase.co/storage/v1/object/public/demo/Collabo%201080x842.jpg?t=2024-03-22T09%3A22%3A48.442Z");
