LoungeDestroyer API for item price list about loungedestroyer HOT 31 CLOSED

This wouldn't be very performance friendly either, as it would, once an hour, request all of the prices. Maybe at initial installation, it'll request them all (or if you do not have any in local storage already) & then if the result is (maybe user defined?) over an hour old, then it'll request it again?

from loungedestroyer.

Don't think it is that bad. It is only one request per hour to our future JSON API, and it easily allows to have a market price for all items on CSGL without delay. The pros outweigh the cons anyway. At the moment market price loading for inventories takes way too much time too if your inventory is huge (100+ items).

There is already another extension that is doing the same actually, but I believe it is 4 hour interval instead. https://chrome.google.com/webstore/detail/csgoloungecom-prices/hgbdpagnjbkhoadnmjcaainaclkmhfla

from loungedestroyer.

Hmm, probably true. Just make sure not to get rate-throttled for the initial request.

from loungedestroyer.

You misunderstood and I didn't explain it properly, the JSON API will be LoungeDestroyer's, hosted on my webserver. It will return all CS:GO items market values at once, single request. The application on my server would fetch steam market prices periodically and store in a database, then cache the response for LD users.

from loungedestroyer.

Ah, that makes more sense. If you put it into one large array, I'm sure you could reduce the bandwidth waste. What about the CPU/sudden BW load on the client side? Would you somehow throttle that, or just let it overload for a few seconds at most?

from loungedestroyer.

Bandwidth shouldn't be a concern since it's just a JSON (list of weaponName => marketValue), and not sure about CPU load but it will just save the API response straight away to Chrome Local Storage. Besides I am already doing two other tasks in the background with AJAX requests: 1) New match checking 2) CS:GO Lounge bot status

from loungedestroyer.

Okay, awesome. Great idea however. Hopefully it'll work out just fine in practice.

from loungedestroyer.

Yep, just need to write it. :( Or find already existing solution.

Wish I could help, but JS isn't my language :P - Good luck though.

from loungedestroyer.

It doesn't need to be JS since its a server application, it can be PHP if you want.

http://csgo.steamanalyst.com/jsonList.php Could reuse this on web application.

How frequent does this update?

from loungedestroyer.

I do not know, but I asked them on subreddit if they have API. http://www.reddit.com/r/steamanalyst/comments/2h1bvf/api_for_developers/

from loungedestroyer.

Possibly save all requested prices to storage, along with timestamp. Then check if item has a price in storage before requesting, and if so, check if timestamp is more than an hour ago. If it is, request new price. Otherwise, load from storage.

Steam API is very poor. I searched for ways to get all marketable items, but I couldn't find a way to get a list of all skins, not even through game files. The classIDs is somewhere located, but I don't know where.

Example API request for an item:
http://api.steampowered.com/ISteamEconomy/GetAssetClassInfo/v0001?key={APIKEY}&format=json&language=en&appid=730&class_count=1&classid0=350539070

After that I figured I could try scraping data from market search instead. Volvo allows to list 100 items per page.

http://steamcommunity.com/market/search/render/?query=&start=0&count=100&search_descriptions=0&sort_column=name&sort_dir=asc&appid=730&currency=1

Currency can be forced if you are not logged in.

Okay, I made some progress, but the market price fetching script needs to be more bullet proof.

from loungedestroyer.

Is this every single item?

from loungedestroyer.

Every item that is on Steam market for CS:GO.

Okay, I made the script more dirtier by applying dirty error handling and retrying for each request (25 requests in total). If anyone wants to see the script, I have it on private repository.

Now to work on the extension part.

from loungedestroyer.

Should we convert the betting value for items too?

from loungedestroyer.

Some progress. I love it how it loads market prices in a lightning speed. 😄 Still not ready to be pushed live though.

Requesting a file is a fucking stupid idea since it comes uncompressed. 250kb (CS:GO only) without gzip compression. 32kb with gzip. Getting rid of quantity property makes it 25kb.

from loungedestroyer.

Doto2 + CS:GO = 180kb. Hmpph.

from loungedestroyer.

Now with Doto2.

from loungedestroyer.

Is this still something that needs to be done? I say we get an API repo created, use NodeJS (keep it javascript since all contrib's have used it?), and get it hosted on Heroku (free service).

from loungedestroyer.

Apologies for necroing this, I am also looking to write a code that will fetch the market data for all available items.

I have looked at what's available on GitHub but it seems all to fetch the data for single items.
Is there something that does it for all items for a game?

from loungedestroyer.

There is no easy way, sadly.

Is there another alternative to get all cs:go weapon skins not ony by one ?

from loungedestroyer.

@xscence
All i know - you can take some classids from here

http://api.steampowered.com/ISteamEconomy/GetAssetPrices/v0001?format=json&language=en&appid=730&key={api_key}

and use them like this

http://api.steampowered.com/ISteamEconomy/GetAssetClassInfo/v0001?key={api_key}&format=json&language=en&appid=730&class_count=91%27&classid0=992003612&classid1=992003613&classid2=927007517&classid3=721248158&classid4=638243112&classid5=613589848&classid6=360448780&classid7=259019412&classid8=186150630&classid9=341265706&classid10=191923205&classid11=186150629&classid12=506856209&classid13=506856210&classid14=613589849&classid15=613589850&classid16=613589851&classid17=613589852&classid18=613589853&classid19=613589854&classid20=613589855&classid21=613589856&classid22=613589857&classid23=613589858&classid24=613589859&classid25=613589860&classid26=613589861&classid27=613589862&classid28=613589863&classid29=613589864&classid30=613589865&classid31=613589866&classid32=615451613&classid33=619637866&classid34=619637867&classid35=619637868&classid36=619637869&classid37=619637870&classid38=619637871&classid39=619637872&classid40=619637873&classid41=619637874&classid42=625567400&classid43=625567401&classid44=625567402&classid45=625567403&classid46=625567404&classid47=625567405&classid48=667021859&classid49=667021860&classid50=667021861&classid51=667021863&classid52=667021864&classid53=667021865&classid54=667021866&classid55=667021867&classid56=667021868&classid57=667021869&classid58=667021870&classid59=667021871&classid60=667021872&classid61=667021873&classid62=783092523&classid63=783092524&classid64=783092525&classid65=783092526&classid66=783092527&classid67=783092528&classid68=783092529&classid69=783092530&classid70=783092532&classid71=783092533&classid72=783092534&classid73=783092535&classid74=783092536&classid75=783092537&classid76=783092538&classid77=783092539&classid78=783092540&classid79=945464709&classid80=945464710&classid81=945464711&classid82=945464712&classid83=945464713&classid84=945464714&classid85=945464715&classid86=945464716&classid87=945464717&classid88=945464718&classid89=945464719&classid90=903185406%27

But, anyway, its not full list of items.

from loungedestroyer.

then how most of the bet websites have all items ? And thanks for your response!
