`steampy` is a library for Python, inspired by node-steam-tradeoffers, node-steam and other libraries for Node.js.
It was designed as a simple lightweight library, combining features of many steam libraries from Node.js into a single python module.
`steampy` is capable of logging into steam, fetching trade offers and handling them in simple manner, using steam user credentials
and SteamGuard file, or by passing sessionID and webCookie cookies.
'steampy' is also capable of using proxies.
`steampy` is developed with Python 3 using type hints and many other features its supported for Windows, Linux and MacOs.

Installation
============

Requires python 3.8 at least
```
pip install steampy
```

Usage
=======
[Obtaining API Key](http://steamcommunity.com/dev/apikey)

[Obtaining SteamGuard from mobile device]( https://github.com/SteamTimeIdler/stidler/wiki/Getting-your-%27shared_secret%27-code-for-use-with-Auto-Restarter-on-Mobile-Authentication )

[Obtaining SteamGuard using Android emulation]( https://github.com/codepath/android_guides/wiki/Genymotion-2.0-Emulators-with-Google-Play-support)

** __init__(self, api_key: str, username: str = None, password: str = None, steam_guard: str = None,
login_cookies: dict = None, proxies: dict = None) -> None:**

SteamClient needs at least api_key to provide some functionalities. User can also provide username, password
and SteamGuard file to be able to log in and use more methods. Proxies are also supported.

```python
from steampy.client import SteamClient

steam_client = SteamClient('MY_API_KEY')
steam_client.login('MY_USERNAME', 'MY_PASSWORD', 'PATH_TO_STEAMGUARD_FILE')
```

User can also provide login_cookies from browser to log in by cookies.

```python
from steampy.client import SteamClient

login_cookies = {} # provide dict with cookies
steam_client = SteamClient('MY_API_KEY',username='MY_USERNAME',login_cookies=login_cookies)
assert steam_client.was_login_executed
```

`proxies` dict can be provided for using proxy for internal SteamClient session.

```python
from steampy.client import SteamClient

proxies = {
"http": "http://login:password@host:port",
"https": "http://login:password@host:port"
}

steam_client = SteamClient('MY_API_KEY', proxies=proxies)

```

If you have `steamid`, `shared_secret` and `identity_secret` you can place it in file `Steamguard.txt` instead of fetching SteamGuard file from device.
```python
{
"steamid": "YOUR_STEAM_ID_64",
"shared_secret": "YOUR_SHARED_SECRET",
"identity_secret": "YOUR_IDENTITY_SECRET"
}
```

Examples
========

You'll need to obtain your API key and SteamGuard file in order to run the examples,
and then fill login and password in `storehose.py` file.
The `storehouse.py` file contains an example of handling incoming trade offers.

```
python storehouse.py
```

If you want to generate authentication codes and use steampy as steam desktop authenticator
then fill required secrets in `desktop_authenticator.py` file.
The `desktop_authenticator.py` file contains examples of generating such one time codes/

```
python desktop_authenticator.py
```

SteamClient methods
===================

Unless specified in documentation, the method does not require login to work(it uses API Key from constructor instead)

**def set_proxy(self, proxy: dict) -> dict**

Set proxy for steampy session, example:

```python
from steampy.client import SteamClient

steam_client = SteamClient('MY_API_KEY')
proxies = {
"http": "http://login:password@host:port",
"https": "http://login:password@host:port"
}
steam_client.set_proxies(proxies)

```

**def set_login_cookies(self, cookies: dict) -> None**

Set login cookies, can be used instead of normal `login` method.

```python
from steampy.client import SteamClient

login_cookies = {} # provide dict with cookies
steam_client = SteamClient('MY_API_KEY',username='MY_USERNAME',login_cookies=login_cookies)
assert steam_client.was_login_executed
```

**login(username: str, password: str, steam_guard: str) -> requests.Response**

Log into the steam account. Allows to accept trade offers and some other methods.

```python
from steampy.client import SteamClient

steam_client = SteamClient('MY_API_KEY')
steam_client.login('MY_USERNAME', 'MY_PASSWORD', 'PATH_TO_STEAMGUARD_FILE')
```

You can also use `with` statement to automatically login and logout.

```python
from steampy.client import SteamClient

with SteamClient('MY_API_KEY', 'MY_USERNAME', 'MY_PASSWORD', 'PATH_TO_STEAMGUARD_FILE') as client:
client.some_method1(...)
client.some_method2(...)
...
```

**logout() -> None**

Using `SteamClient.login` method is required before usage
Logout from steam.

```python
from steampy.client import SteamClient

steam_client = SteamClient('MY_API_KEY')
steam_client.login('MY_USERNAME', 'MY_PASSWORD', 'PATH_TO_STEAMGUARD_FILE')
steam_client.logout()
```

You can also use `with` statement to automatically login and logout.

```python
from steampy.client import SteamClient

with SteamClient('MY_API_KEY', 'MY_USERNAME', 'MY_PASSWORD', 'PATH_TO_STEAMGUARD_FILE') as client:
client.some_method1(...)
client.some_method2(...)
...
```

**is_session_alive() -> None**

Using `SteamClient.login` method is required before usage
Check if session is alive. This method fetches main page and check
if user name is there. Thanks for vasia123 for this solution.

```python
from steampy.client import SteamClient

steam_client = SteamClient('MY_API_KEY')
steam_client.login('MY_USERNAME', 'MY_PASSWORD', 'PATH_TO_STEAMGUARD_FILE')
is_session_alive = steam_client.is_session_alive()
```

**api_call(request_method: str, interface: str, api_method: str, version: str, params: dict = None) -> requests.Response**

Directly call api method from the steam api services.

[Official steam api site](https://developer.valvesoftware.com/wiki/Steam_Web_API)

[Unofficial but more elegant](https://lab.xpaw.me/steam_api_documentation.html)

```python
from steampy.client import SteamClient

steam_client = SteamClient('MY_API_KEY')
params = {'key': 'MY_API_KEY'}
summaries = steam_client.api_call('GET', 'IEconService', 'GetTradeOffersSummary', 'v1', params).json()
```
**get_trade_offers_summary() -> dict**

**get_trade_offers(merge: bool = True) -> dict**

Fetching trade offers from steam using an API call.
Method is fetching offers with descriptions that satisfy conditions:

* Are sent by us or others
* Are active (means they have `trade_offer_state` set to 2 (Active))
* Are not historical
* No time limitation

If `merge` is set `True` then offer items are merged from items data and items description into dict where items `id` is key
and descriptions merged with data are value.

**get_trade_offer(trade_offer_id: str, merge: bool = True) -> dict**

**get_trade_receipt(trade_id: str) -> list**

Using `SteamClient.login` method is required before usage
Getting the receipt for a trade with all item information after the items has been traded.
Do NOT store any item ids before you got the receipt since the ids may change.
"trade_id" can be found in trade offers: `offer['response']['offer']['tradeid']`. Do not use ´tradeofferid´.

**make_offer(items_from_me: List[Asset], items_from_them: List[Asset], partner_steam_id: str, message:str ='') -> dict**

Using `SteamClient.login` method is required before usage
`Asset` is class defined in `client.py`, you can obtain `asset_id` from `SteamClient.get_my_inventory` method.
This method also uses identity secret from SteamGuard file to confirm the trade offer.
No need to manually confirm it on mobile app or email.
This method works when partner is your friend or steam.
In returned dict there will be trade offer id by the key `tradeofferid`.

```python
from steampy.client import SteamClient, Asset
from steampy.utils import GameOptions

steam_client = SteamClient('MY_API_KEY')
steam_client.login('MY_USERNAME', 'MY_PASSWORD', 'PATH_TO_STEAMGUARD_FILE')
partner_id = 'PARTNER_ID'
game = GameOptions.CS
my_items = steam_client.get_my_inventory(game)
partner_items = steam_client.get_partner_inventory(partner_id, game)
my_first_item = next(iter(my_items.values()))
partner_first_item = next(iter(partner_items.values()))
my_asset = Asset(my_first_item['id'], game)
partner_asset = Asset(partner_first_item['id'], game)
steam_client.make_offer([my_asset], [partner_asset], partner_id, 'Test offer')
```

**make_offer_with_url(items_from_me: List[Asset], items_from_them: List[Asset], trade_offer_url: str, message: str = '', case_sensitive: bool = True) -> dict**

Using `SteamClient.login` method is required before usage
This method is similar to `SteamClient.make_offer`, but it takes trade url instead of friend account id.
It works even when partner isn't your steam friend
In returned dict there will be trade offer id by the key `tradeofferid`.
If `case_sensitive` is False, then url params with be parsed with case insensitive params keys.

**get_escrow_duration(trade_offer_url: str) -> int**

Using `SteamClient.login` method is required before usage

Check the escrow duration for trade between you and partner(given partner trade offer url)

**accept_trade_offer(trade_offer_id: str) -> dict**

Using `SteamClient.login` method is required before usage
This method also uses identity secret from SteamGuard file to confirm the trade offer.
No need to manually confirm it on mobile app or email.

**decline_trade_offer(trade_offer_id: str) -> dict**

Decline trade offer that **other** user sent to us.

**cancel_trade_offer(trade_offer_id: str) -> dict**

Cancel trade offer that **we** sent to other user.

**get_my_inventory(game: GameOptions, merge: bool = True, count: int = 5000) -> dict**

Using `SteamClient.login` method is required before usage

If `merge` is set `True` then inventory items are merged from items data and items description into dict where items `id` is key
and descriptions merged with data are value.

`Count` parameter is default max number of items, that can be fetched.

Inventory entries looks like this:

```python
inventory_entry = {'7146788981': {'actions': [{

**get_partner_inventory(partner_steam_id: str, game: GameOptions, merge: bool = True, count: int = 5000) -> dict**

Using `SteamClient.login` method is required before usage

Inventory items can be merged like in `SteamClient.get_my_inventory` method

`Count` parameter is default max number of items, that can be fetched.

**get_wallet_balance(convert_to_decimal: bool = True, on_hold: bool = False) -> Union[str, float]**

Check account balance of steam acccount. It converts money string to Decimal if `convert_to_decimal` is set to `True`,
otherwise, it will return the value string without a decimal point.
If the `on_hold` parameter is set to `True`, it will return the current on-hold balance value.

Example:
```python
from steampy.client import SteamClient
from decimal import Decimal
with SteamClient('MY_API_KEY', 'MY_USERNAME', 'MY_PASSWORD', 'PATH_TO_STEAMGUARD_FILE') as client:
wallet_balance = client.get_wallet_balance()
on_hold_wallet_balance = client.get_wallet_balance(on_hold = True)
assert type(wallet_balance) == Decimal
assert type(on_hold_wallet_balance) == Decimal
```

market methods
==============

**fetch_price(item_hash_name: str, game: GameOptions, currency: str = Currency.USD) -> dict**

Some games are predefined in `GameOptions` class, such as `GameOptions.DOTA2`, `GameOptions.CS` and `GameOptions.TF2,
but `GameOptions` object can be constructed with custom parameters.

Currencies are defined in Currency class, [currently](https://github.com/bukson/steampy#currencies)

Default currency is USD

May rise `TooManyRequests` exception if used more than 20 times in 60 seconds.

```python
from steampy.client import SteamClient
from steampy.models import GameOptions

steam_client = SteamClient('API_KEY')
item = 'M4A1-S | Cyrex (Factory New)'
price = steam_client.market.fetch_price(item, game=GameOptions.CS)
# price == {'volume': '208', 'lowest_price': '$11.30 USD', 'median_price': '$11.33 USD', 'success': True}
```

**fetch_price_history(item_hash_name: str, game: GameOptions) -> dict**

Using `SteamClient.login` method is required before usage

response = client.market.fetch_price_history(item, GameOptions.CS)
response['prices'][0]
['Jul 02 2014 01: +0', 417.777, '40']
```

Each entry in `response['prices']` is a list, with first entry being date, second entry price, and third entry a volume.

guard module functions
======================

**load_steam_guard(steam_guard: str) -> dict**

If `steam_guard` is file name then load and parse it, else just parse `steam_guard` as json string.

**generate_one_time_code(shared_secret: str, timestamp: int = None) -> str**

Generate one time code for logging into Steam using shared_secret from SteamGuard file.
If none timestamp provided, timestamp will be set to current time.

**generate_confirmation_key(identity_secret: str, tag: str, timestamp: int = int(time.time())) -> bytes**

Generate mobile device confirmation key for accepting trade offer.
Default timestamp is current time.

Utils methods
======================

**calculate_gross_price(price_net: Decimal, publisher_fee: Decimal, steam_fee: Decimal = Decimal('0.05')) -> Decimal:**

Calculate the price including the publisher's fee and the Steam fee. Most publishers have a `10%` fee with a minimum
fee of `$0.01`. The Steam fee is currently `5%` (with a minimum fee of `$0.01`) and may be increased or decreased by
Steam in the future.

Returns the amount that the buyer pays during a market transaction:

```python
from decimal import Decimal
from steampy.utils import calculate_gross_price

publisher_fee = Decimal('0.1') # 10%

calculate_gross_price(Decimal('100'), publisher_fee) # returns Decimal('115')
```

**calculate_net_price(price_gross: Decimal, publisher_fee: Decimal, steam_fee: Decimal = Decimal('0.05')) -> Decimal:**

Calculate the price without the publisher's fee and the Steam fee. Most publishers have a `10%` fee with a minimum fee
of `$0.01`. The Steam fee is currently `5%` (with a minimum fee of `$0.01`) and may be increased or decreased by Steam
in the future.

Returns the amount that the seller receives after a market transaction:

```python
from decimal import Decimal
from steampy.utils import calculate_net_price

publisher_fee = Decimal('0.1') # 10%

calculate_net_price(Decimal('115'), publisher_fee) # returns Decimal('100')
```

Test
====

All public methods are documented and tested.
`guard` module has unit tests, `client` uses an acceptance test.
For the acceptance test you have to put `credentials.pwd` and `Steamguard` file into `test` directory

Example `credentials.pwd` file:

```
account1 password1 api_key1
account2 password2 api_key2
```

In some tests you also have to obtain `transaction_id`.
You can do it by `SteamClient.get_trade_offers` or by logging manually into steam account in browser and get it from url

In some tests you also have to obtain partner steam id.
You can do it by logging manually into steam account in browser and get it from url
