# Lost Invention Mission

The Lost Invention Mission is an interactive guide that helps users understand how to utilize the API for retrieving information about lost inventions. This document provides step-by-step instructions and code samples in both TypeScript and Python.

## Before You Begin

Make sure you have the following before you start:

- Your API key
- The base API URL


## Configure Your API Key and Base URL

To interact with the API, you need to set your API key and base URL. You can do this in the code samples provided below.

## Add Steps for Left Panel

Define a section in the left panel by wrapping content with the `step` tag. Each step must have a unique `id`.

### Step 1: Set Up Your Environment

1. Clone the repository.
2. Navigate to the `_filesets` directory for the language you want to use (TypeScript or Python).
3. Install the necessary dependencies.


### Step 2: Configure API Key and Base URL

In the `usage.ts` or `usage.py` file, set your API key and base URL as follows:


```typescript
// TypeScript
const apiKey = 'YOUR_API_KEY';
const baseUrl = 'YOUR_BASE_API_URL';
```


```python
# Python
api_key = 'YOUR_API_KEY'
base_url = 'YOUR_BASE_API_URL'
```

### Step 3: Make API Requests

Use the SDK functions to make requests to the API. Refer to the `usage.ts` or `usage.py` file for examples of how to call these functions.


```typescript
// TypeScript
import { fetchInventions } from './sdk';

fetchInventions(apiKey, baseUrl);
```


```python
# Python
from sdk import fetch_inventions

fetch_inventions(api_key, base_url)
```

## Chunks for Right Panel

Use chunk annotations to control which lines are highlighted in the right panel when a step becomes active in a code walkthrough.

### TypeScript SDK Implementation


```typescript sdk.ts
export async function fetchInventions(apiKey: string, baseUrl: string) {
    const response = await fetch(`${baseUrl}/inventions`, {
        headers: {
            'Authorization': `Bearer ${apiKey}`
        }
    });
    return response.json();
}
```

### TypeScript Usage Example


```typescript usage.ts
import { fetchInventions } from './sdk';

const apiKey = 'YOUR_API_KEY';
const baseUrl = 'YOUR_BASE_API_URL';

fetchInventions(apiKey, baseUrl).then(data => {
    console.log(data);
});
```

### Python SDK Implementation


```python sdk.py
import requests

def fetch_inventions(api_key, base_url):
    response = requests.get(f"{base_url}/inventions", headers={
        'Authorization': f'Bearer {api_key}'
    })
    return response.json()
```

### Python Usage Example


```python usage.py
from sdk import fetch_inventions

api_key = 'YOUR_API_KEY'
base_url = 'YOUR_BASE_API_URL'

data = fetch_inventions(api_key, base_url)
print(data)
```
