### About

**Pseudo API for Google Trends**

* Allows simple interface for automating downloads of csv reports from Google Trends.
* Main feature is to help trick google into thinking the script is actually a browser.


* Only good until Google changes their backend again :-P

```pip install pytrends```

**Requirements**
* Written for both Python 2.7+ and Python 3.3+
* Requires a google account to use.
* Requires BeautifulSoup4, Requests, lxml

**Caveats**
* This is not an official or supported API
* Google may change aggregation level for items with very large or very small search volume

## Connect to Google

### Request a Report
**`request_report(payload)`**

* Advanced Keywords
- When using Google Trends dashboard Google may provide suggested narrowed search terms.
- For example ```"iron"``` will have a drop down of ```"Iron Chemical Element, Iron Cross, Iron Man, etc"```.
- Find the encoded topic by using the get_suggestions() function and choose the most relevant one for you.
- For example: ```https://www.google.com/trends/explore#q=%2Fm%2F025rw19&cmpt=q```
- ```"%2Fm%2F025rw19"``` is the topic "Iron Chemical Element" to use this with pytrends
* `hl`
- Language to return result headers in
- Two letter language abbreviation
- For example US English is ```{'hl': 'en-US'}```
- Defaults to US english
* `cat`
- Category to narrow results
- Find available cateogies by inspecting the url when manually using Google Trends. The category starts after ```cat=``` and ends before the next ```&```
- For example: ```"https://www.google.com/trends/explore#q=pizza&cat=0-71"```
- ```{'cat': '0-71'}``` is the category
- Defaults to no category
* `geo`
- Two letter country abbreviation

- Timezone using Etc/GMT
- For example US CST is ```{'tz': 'Etc/GMT+5'}```

- Custom Timeframe Pattern:
- By Month: ```{'date': 'MM/YYYY #m'}``` where # is the number of months from that date to pull data for
- For example: ``{'date': '10/2009 61m'}`` would get data from October 2009 to October 2014
- Less than 4 months will return Daily level data
- More than 36 months will return monthly level data
- 4-36 months will return weekly level data
- Current Time Minus Time Pattern:
- By Month: ```{'date': 'today #-m'}``` where # is the number of months from that date to pull data for
- For example: ``{'date': 'today 61-m'}`` would get data from today to 61months ago
- 1-3 months will return daily intervals of data
- 4-36 months will return weekly intervals of data
- 36+ months will return monthly intervals of data
- **NOTE** Google uses UTC date as *'today'*
- Daily: ```{'date': 'today #-d'}``` where # is the number of days from that date to pull data for
- For example: ``{'date': 'today 7-d'}`` would get data from the last week
- 1 day will return 8min intervals of data
- 2-8 days will return Hourly intervals of data
