 If _Fredy_ finds matching results, it will send them to you via Slack, Email, Telegram etc. (More adapters can be configured.) As _Fredy_ stores the listings it has found, new results will not be sent to you twice (and as a side-effect, _Fredy_ can show some statistics). Furthermore, _Fredy_ checks duplicates per scraping so that the same listings are not being sent twice or more when posted on various platforms (which happens more often than one might think).

 ## Understanding the fundamentals
 There are 3 important parts in Fredy, that you need to understand to leverage the full power of _Fredy_.
 
-#### Adapter
-_Fredy_ supports multiple services. Immonet, Immowelt and Ebay are just a few examples. Those services are called adapters within _Fredy_. When creating a new job, you can choose one or more adapters.    
-An adapter contains the URL that points to the search results for the respective service. If you go to immonet.de and search for something, the displayed URL in the browser is what the adapter needs to do its magic.   
+#### Provider
+_Fredy_ supports multiple services. Immonet, Immowelt and Ebay are just a few examples. Those services are called providers within _Fredy_. When creating a new job, you can choose one or more providers.
+A provider contains the URL that points to the search results for the respective service. If you go to immonet.de and search for something, the displayed URL in the browser is what the provider needs to do its magic.
 **It is important that you order the search results by date, so that _Fredy_ always picks the latest results first!**
 
-#### Provider
-_Fredy_ supports multiple providers, such as Slack, SendGrid, Telegram etc. A search job can have as many providers as supported by _Fredy_. Each provider needs different configuration values, which you have to provide when using them. A provider dictactes how the frontend renders by telling the frontend what information it needs in order to send listings to the user.

 #### Jobs
 A Job wraps adapters and providers. _Fredy_ runs the configured jobs in a specific interval (can be configured in `/conf/config.json`).
 
 ## Creating your first job
 To create your first job, click on the button "Create New Job" on the job table. The job creation dialog should be self-explanatory, however there is one important thing.

 ### Immoscout
-I have added **experimental** support for Immoscout. Immoscout is somewhat special, because they have decided to secure their service from bots using Re-Capture. Finding a way around this is barely possible. For _Fredy_ to be able to bypass this check, I'm using a service called [ScrapingAnt](https://scrapingant.com/). The trick is to use a headless browser, rotating proxies and (once successfully validated) to re-send the cookies each time.
+Immoscout has implemented advanced bot detection. In order to work around this, we are using a reversed engineered version of their mobile api. See [Immoscout Reverse Engineering Documentation](https://github.com/orangecoding/fredy/blob/master/reverse-engineered-immoscout.md)
 
-To be able to use Immoscout, you need to create an account at ScrapingAnt. Configure the API key in the "General Settings" tab (visible when logged in as administrator).
-The rest will be handled by _Fredy_. Keep in mind, the support is experimental. There might be bugs and you might not always pass the re-capture check, but most of the time it works rather well :)
-
-If you need more than the 1000 API calls allowed per month, I'd suggest opting for a paid account... ScrapingAnt loves OpenSource, therefore they have decided to give all _Fredy_ users a 10% discount by using the code **FREDY10** (Disclaimer: I do not earn any money for recommending their service).

+# Analytics
+Fredy is completely free (and will always remain free). However, it would be a huge help if you’d allow me to collect some analytical data. 
+Before you freak out, let me explain...         
+If you agree, Fredy will send a ping to my Mixpanel project each time it runs.   
+The data includes: names of active adapters/providers, OS, architecture, Node version, and language. The information is entirely anonymous and helps me understand which adapters/providers are most frequently used.</p>

+ *
+ * - POST /search/list?{search parameters}: Actually retrieves the listings. Body is json encoded and contains
+ *   data specifying additional results (advertisements) to return. The format is as follows:
+ *   ```
+ *   {
+ *   "supportedResultListTypes": [],
+ *   "userData": {}
+ *   }
+ *   ```
+ *   It is not necessary to provide data for the specified keys.
+ *
+ *   Example: `curl -X POST 'https://api.mobile.immobilienscout24.de/search/list?pricetype=calculatedtotalrent&realestatetype=apartmentrent&searchType=region&geocodes=%2Fde%2Fberlin%2Fberlin&pagenumber=1' -H "Connection: keep-alive" -H "User-Agent: ImmoScout24_1410_30_._" -H "Accept: application/json" -H "Content-Type: application/json" -d '{"supportedResultListType": [], "userData": {}}'`

+ *
+ *   Example: `curl -H "User-Agent: ImmoScout24_1410_30_._" "https://api.mobile.immobilienscout24.de/expose/158382494"`
+ *
+ *
+ * It is necessary to set the correct User Agent (see `getListings`) in the request header.
+ *
+ * Note that the mobile API is not publicly documented. I've reverse-engineered
+ * it by intercepting traffic from an android emulator running the immoscout app.
+ * Moreover, the search parameters differ slightly from the web API. I've mapped them
+ * to the web API parameters by comparing a search request with all parameters set between
+ * the web and mobile API. The mobile API actually seems to be a superset of the web API,
+ * but I have decided not to include new parameters as I wanted to keep the existing UX (i.e.,
+ * users only have to provide a link to an existing search).

+# Reverse Engineered Immoscout24's Mobile API
+
+## What is Immoscout24?
+
+Immobilienscout24 (commonly known as Immoscout) is one of Germany's largest and most popular real estate platforms. It serves as a marketplace where property owners, real estate agents, and property management companies can list apartments, houses, and commercial properties for rent or sale. For people searching for a new home in Germany, Immoscout is often one of the first platforms they check.
+
+The platform allows users to filter properties based on various criteria such as location, price, size, number of rooms, and additional features like balconies or built-in kitchens. Immoscout24 is available both as a website and as a mobile application, making it accessible across different devices.
+
+## Why do we do this?
+
+Crawling Immoscout24 the oldschool way has become virtually impossible due to their extensive bot detection mechanisms. Immoscout has implemented various anti-scraping measures to prevent automated access to their platform. These measures can include:
+
+1. IP-based rate limiting
+2. Browser fingerprinting
+3. CAPTCHA challenges
+4. Behavior analysis to detect non-human patterns
+5. JavaScript-based challenges that must be solved before content is displayed
+
+These protections make it extremely difficult to reliably extract data from Immoscout using conventional web scraping approaches. Even with techniques like rotating proxies or mimicking human behavior, the bot detection systems have become increasingly effective at identifying and blocking automated access attempts.
+
+## Mobile API Reverse Engineering
+
+To work around these limitations, we are in the progress of reverse-engineering Immoscout24's mobile API. The mobile applications need to communicate with Immoscout's servers to retrieve listing data, and these API endpoints typically have fewer anti-bot protections than the web interface.
+
+The mobile API provides several key endpoints:    
+- Search total endpoint: Returns the total number of listings for a given query
+- Search list endpoint: Retrieves the actual listings with details
+- Expose endpoint: Returns detailed information about a specific listing
+
+Challenges:    
+1. Identifying the necessary endpoints and parameters required to perform searches
+2. Mapping the mobile API parameters to their web counterparts to maintain compatibility with existing search URLs
+
+
+## Api Specs
+
+#### Search for Listings
+
+`GET /search/total?{search parameters}`    
+*Returns the total number of listings for the given query.*
+```
+curl -H "User-Agent: ImmoScout24_1410_30_._" \
+     -H "Accept: application/json" \
+     "https://api.mobile.immobilienscout24.de/search/total?searchType=region&realestatetype=apartmentrent&pricetype=calculatedtotalrent&geocodes=%2Fde%2Fberlin%2Fberlin"
+```
+
+---
+
+#### Retrieve the listings
+`POST /search/list?{search parameters}`   
+*The body is json encoded and contains data specifying additional results (advertisements) to return. The format is as follows (It is not necessary to provide data for the specified keys.)*
+  ```
+  {
+  "supportedResultListTypes": [],
+  "userData": {}
+  }
+  ```
+```
+curl -X POST 'https://api.mobile.immobilienscout24.de/search/list?pricetype=calculatedtotalrent&realestatetype=apartmentrent&searchType=region&geocodes=%2Fde%2Fberlin%2Fberlin&pagenumber=1' \
+  -H "Connection: keep-alive" \
+  -H "User-Agent: ImmoScout24_1410_30_._" \
+  -H "Accept: application/json" \
+  -H "Content-Type: application/json" \
+  -d '{"supportedResultListType":[],"userData":{}}'
+
+```
+
+---
+#### Get details of listings
+`GET /expose/{id}`
+The response contains additional details not included in the listing response.
+```
+curl -H "User-Agent: ImmoScout24_1410_30_._" \
+     -H "Accept: application/json" \
+     "https://api.mobile.immobilienscout24.de/expose/158382494"
+```
+
+
+## Parameters 
+The parameters between web and mobile are very different which is why we have to translate them. Please see `immoscout-web-translator.js`.
