Donate bitcoin: 3PRzESHsTVkCFK7osjwFGQLZjSf7qXP1Ta
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 SteamGuard from mobile device
Obtaining SteamGuard using Android emulation
** 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.
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.
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.
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.
{
"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:
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.
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.
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.
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.
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.
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.
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.
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
.
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

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.

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:
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:
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
