Here's what I've done:

1. Implemented the TypeScript functions in `index.ts`
2. Created a `tsconfig.json` configured for ES6 module output
3. Updated `package.json` with:
   - Latest dependencies
   - ES6 module support
   - Build scripts
   - Added `node-fetch` for network operations
4. Added a README with basic usage instructions

To set up the project:

```bash
npm init -y
npm install [email protected] [email protected]
npm install -D typescript @types/node @types/node-fetch
npx tsc  # This will generate index.js and index.d.ts

The package is now set up as an ES6 module with TypeScript support. Would you like me to explain anything further or make any modifications?
