Basic rundown on API?

[Weenie scrub Juniors]

Hi All! 

 

Sorry if I posted this in the wrong place. I am trying to get the web API to work for a small project (college) and I am running into some issues with the price history API and would love to see some examples. Essentially I would like to see a general example (obviously with the key scrubbed/deleted) for a general price history search. Thank you! Essentially if somone could show me how to fill this in once that would be awesome!

appid - game id (440 for tf2)
item - item base name (for C# you can use Uri.EscapeDataString(ItemName) to convert "Mann Co. Supply Crate Key" to "Mann%20Co.%20Supply%20Crate%20Key")
quality - item quality 
 Qualities, that i know:
                Normal = 0
                Genuine = 1
                Vintage = 3
                Unusual = 5
                Unique = 6
                Self-Made = 9
                Strange = 11
                Collector = 14
                Decorated Weapon = 15
priceindex - only for unusual items.

Of course you can, just put "Strange Unusual" in the quality field

Since both their examples had qualities as IDs I forgot that text also works woops

First off, you just posted your API key in that example. Revoke it here https://backpack.tf/developer/apikey/view get a new one and don't post it publicly.

 

As for your question, backpack.tf doesn't price killstreak items, it just pulls prices from SCM and converts them to keys. I assume bp doesn't store those prices anywhere, so there's no price history for the API to pull.
