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

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
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.
