Supported Marketplaces and Providers

A provider is a CS2 marketplace that CS2Cap indexes for pricing, bid, and sales data. Each provider has a short string key — such as steam, buff163, or csfloat — that you use in request parameters. Always use the provider key, not the marketplace’s display name or brand name. You can filter most market-data endpoints to one or more providers using the repeatable providers query parameter:

GET /prices?market_hash_name=AK-47+%7C+Redline+(Field-Tested)&providers=steam&providers=buff163

This endpoint is available to all tiers (free, starter, pro, quant) at the standard rate limit for your tier.

Provider response fields

The response is a JSON object keyed by the provider’s display name. Each entry contains the following fields:

Example response

{
  "Avan Market": {
    "key": "avanmarket",
    "code": "AVAN",
    "market_type": "STORE",
    "default_currency": "USD",
    "fees": {
      "sell_fee": null,
      "insta_sell_fee": 0.14,
      "trading_spread_fee": null
    },
    "features": {
      "has_buy_orders": false,
      "has_recent_sales": false
    },
    "health": {
      "status": "up",
      "last_checked_at": "2026-03-21T05:47:49.308777+00:00",
      "total_offers": 221316,
      "unique_items": 14792,
      "market_coverage": 37.93,
      "total_value": 696770885,
      "total_value_usd": 696770885
    }
  },
  "BUFF163": {
    "key": "buff163",
    "code": "B163",
    "market_type": "P2P",
    "default_currency": "CNY",
    "fees": {
      "sell_fee": 0.025,
      "insta_sell_fee": null,
      "trading_spread_fee": null
    },
    "features": {
      "has_buy_orders": true,
      "has_recent_sales": true
    },
    "health": {
      "status": "up",
      "last_checked_at": "2026-03-21T05:45:55.403317+00:00",
      "total_offers": 4239178,
      "unique_items": 32235,
      "market_coverage": 82.66,
      "total_value": 101161038598,
      "total_value_usd": 14661379184
    }
  }
}

health.total_value is denominated in the provider’s native default_currency in minor units. health.total_value_usd converts that same value to USD. Both fields use minor units — divide by 100 for display.

Using the providers parameter

The providers parameter is repeatable. Pass it multiple times to query several providers in one request:

GET /prices?market_hash_name=AK-47+%7C+Redline+(Field-Tested)&providers=steam&providers=buff163&providers=csfloat

The meta.returned_providers field in the response tells you which providers actually returned data for that query — it may be a subset of what you requested if a provider is down or has no listings for the item.
