Steam Market API?

Question

I know that there's a Steam API allowing me to use data from Steam Community.
My question is, does anyone know if there's a Steam Market API?
For example, I want to get the current price of an item in the Steam Market.

I've googled and haven't found anything yet.
I'd be glad to have your help.

If there isn't an API, you should be able to scrape the HTML for the tag containing the price. Check this out #23056173 – Minimum

Answer 1

I could not find any documentation, but I use:

http://steamcommunity.com/market/priceoverview/?appid=730&currency=3&market_hash_name=StatTrak%E2%84%A2 M4A1-S | Hyper Beast (Minimal Wear)

to return a JSON. At time of writing, it returns:

{"success":true,"lowest_price":"261,35€ ","volume":"11","median_price":"269,52€ "}

You can change the currency. 1 is USD, 3 is euro but there are probably others.

This is the best solution I'm aware of if you want just one item. If you want an entire game though, backpack.tf provides their own API that updates (at least hourly if not more often): backpack.tf/api/market Their servers seem faster and more stable than Valve's. – Terry

Also, Valve will temporary ban you (for a few minutes) if you ask excessively. – Scallop

@rannman looks like the URL has changed. Here's the developer page, which includes links to the API docs for CSGO on backpack: csgo.backpack.tf/developer – Nuncle

what does the volume object mean? – Amuck

@Violet I'm pretty sure this is the number of items sold in the last 24h – Scallop

@Scallop yup when using this, caching is absolutely essential – Moskowitz

Why do I sometimes get a response like {"success": true, "volume": 29, "median_price": "$3.45"} and I get no lowest_price? – Marcel

Answer 2

A better search api that can give you all the results for a game, example using pubg which only has 272 items, if your game has more try changing the count parameter at the end

https://steamcommunity.com/market/search/render/?search_descriptions=0&sort_column=default&sort_dir=desc&appid=578080&norender=1&count=500

Eccrinology

Even if count >100; it still only shows 100 results. I solved that by multiple requests utilizing the start parameter. – Phosphaturia

Use sort_column=name as well. I think its random if you use default – Medullary

Answer 3

Using the currency parameter you can change which local currency steam returns.

&currency=1 # USD
&currency=2 # GBP
&currency=3 # EUR
&currency=4 # CHF
...

You can use 34 for Argentinian pesos, not sure why 33 isn't being used though. – Zeph

Answer 4

To add to what the other people have said, the temporary ban on the JSON site happens if you try and request 20 items within a minute's time from the server. If you're creating a script to request those links, add a three second delay between each script. Also, the ban only lasts for the remaining server-side minute (which may not be 60 seconds).

This doesn't answer the question. – Haplite

Answer 5

You can use SteamApis.com to acquire Steam market prices and item information. The data is returned in JSON. The service is not free but also not that expensive.

The documentation is available to view here. It has detailed information on what endpoints are available and what data is returned.

Answer 6

Script-scraper which maps search results from https://steamcommunity.com/market/search?q= to array of objects

Array.from(document.querySelectorAll('a.market_listing_row_link')).map(item => {
  const itemInfo = item.children[0]
  return {
    isStatTrek: itemInfo.getAttribute('data-hash-name').startsWith('StatTrak™'),
    condition: itemInfo.getAttribute('data-hash-name').match(/.*\((.*)\)/)[1],
    priceUSD: Number(itemInfo.querySelector('.normal_price[data-price]').getAttribute('data-price')/100)
  }
})

can be used with iframe and "weapon | skin name (condition)" search template
