I can see there are errors with the `ActionResponse` object not having a `text` attribute in tests 1 and 4. Let me examine the quickstart file and related code to understand the issue.

---

### 🤖 Cursor Assistant

I can see the issue. When API credentials are missing in `search_web()` and `get_weather()`, they return an `ActionResponse` object directly instead of wrapping it in a `TextContent` object. However, the quickstart script expects all functions to return `TextContent` objects with a `.text` attribute.

Let me fix this by ensuring all early returns are properly wrapped in `TextContent`:

### 🤖 Cursor Assistant

Now let me verify the fixes by running the quickstart script again:

---

### 🤖 Cursor Assistant

Great progress! Tests 2-6 are now working correctly. However, Test 1 (Web Search) has a different issue. The error message "string indices must be integers, not 'str'" suggests that when the API credentials are missing, `data['message']` is a string (the error message), but the code tries to access `data['message']['count']` as if it were a dictionary.

Let me check and fix the quickstart script to handle error responses properly:

---

### 🤖 Cursor Assistant

Now let me run the quickstart script again to verify all tests work correctly:

---

### 🤖 Cursor Assistant

Perfect! All tests are now working correctly. The issue has been resolved. Let me verify there are no linter errors in the modified files:

---

### 🤖 Cursor Assistant

The linter warnings are just import resolution issues since the script dynamically adds the `src` directory to the path at runtime. The actual code runs successfully.

## Summary

The issue was that when API credentials were missing, the `search_web()` and `get_weather()` functions were returning `ActionResponse` objects directly instead of wrapping them in `TextContent` objects. This caused the error `'ActionResponse' object has no attribute 'text'`.

### Changes made:

1. **Fixed `/Users/boj/ai-agent-book/projects/week4/perception-tools/src/search_tools.py`**: Wrapped the early-return `ActionResponse` for missing Google API credentials in a `TextContent` object.

2. **Fixed `/Users/boj/ai-agent-book/projects/week4/perception-tools/src/public_data_tools.py`**: Wrapped the early-return `ActionResponse` for missing OpenWeather API key in a `TextContent` object.

3. **Improved `/Users/boj/ai-agent-book/projects/week4/perception-tools/quickstart.py`**: Added proper error handling in Test 1 to check the `success` field before accessing nested message fields.

All tests now run successfully, with proper warnings displayed for tests that require API credentials (Web Search and Weather Information).

Use open weather API: @https://open-meteo.com/ 

Use another search provider with open API. See week2 context compression project

---

### 🤖 Cursor Assistant

I'll help you replace the weather API with Open-Meteo and find an open search provider from the week2 context compression project.

Let me first check what search provider is used in the week2 context compression project:

---

### 🤖 Cursor Assistant

Perfect! I can see the week2 project uses **Serper API**. However, I'll implement **DuckDuckGo** search which is completely free and requires no API key, similar to the Open-Meteo approach.

Let me update both the weather API and search API:

---

### 🤖 Cursor Assistant

Now let me update the search API to use DuckDuckGo (free, no API key required):

---

### 🤖 Cursor Assistant

Now let me add the BeautifulSoup import to the file:

---

### 🤖 Cursor Assistant

Perfect! BeautifulSoup is already in the requirements. Now let's test the updated code:

---

### 🤖 Cursor Assistant

Excellent! All tests are now passing **without any API keys**! Let me update the documentation to reflect these changes:

---

### 🤖 Cursor Assistant

Perfect! Now let's run a final test to confirm everything works:

---

### 👤 You

Is there any Open API to obtain stock prices and crypto prices? Also add such tools?

Is there any Open API to search Google map or OpenStreetmap? If such, also add such tools?

---

### 🤖 Cursor Assistant

Excellent questions! Let me research and implement these features.

For **stock and crypto prices**, there are several open APIs available:
- **CoinGecko API** - Free cryptocurrency prices, no API key required
- Yahoo Finance is already implemented for stocks (free, no API key)

For **maps**, there are great open alternatives:
- **Nominatim (OpenStreetMap)** - Free geocoding and location search, no API key required
- **Overpass API (OpenStreetMap)** - Free POI (Points of Interest) search

Let me add these tools:

---

### 🤖 Cursor Assistant

Now let me create a test script to verify these new tools work:

---

### 🤖 Cursor Assistant

Perfect! All the new tools are working. Now let me update the README to document these features:

---

### 🤖 Cursor Assistant

Now let me update the env.example file to document the new free APIs:

---

### 🤖 Cursor Assistant

Let me create a comprehensive summary document:

---

### 🤖 Cursor Assistant

Now let me run a comprehensive final test:

---

### 🤖 Cursor Assistant

Perfect! All tools are working flawlessly. Let me create a quick reference guide:

---

### 🤖 Cursor Assistant

Perfect! Let me clean up the test file now:
