What the Steam API does not give you.
Valve's Steam Web API covers accounts, inventories and some game stats, and Game State Integration streams your own game client. Neither covers pro matches, and the Steam Market is one price among many.

Give Claude, Cursor and ChatGPT the CS2 data. One command writes the MCP config; agents call live scoreboard, team map stat, opening duel and transfer tools instead of inventing match IDs, and your key stays on your machine.

The CS2 data Steam does not have
Pair Steam for accounts and inventories with this API for esports and prices.
Pro match data
Results, maps and box scores from pro matches.
Live pro scores
Every tracked match in progress, not just your client.
Player stats
Ratings, ADR and KAST for pro players.
Cross-market prices
Steam and third-party marketplaces side by side.
Price history
Daily prices going back years on long-listed skins.
No inventories
Inventories stay with Steam; this API prices what is in them.
Steam, GSI and a CS2 API
| Need | Steam Web API / GSI | CS2 API (Cito) |

| Rate limit | 100,000 calls a day per key | Per plan, with Retry-After on 429 |
| Live pro scores | GSI streams only a client you run | Every tracked match |
| Player inventories | Yes | No |
| Skin prices | Steam Community Market only | Steam plus third-party markets |
| Price history | Steam Market only | Daily cheapest across markets |
| Pro player ratings | Not covered | Rating, ADR, KAST per map |
Does the Steam Web API have CS2 match history?
No. In Valve's catalogue of Steam Web API methods, GetMatchHistory exists only for Dota 2. CS:GO never had one, and neither does CS2.
The closest thing is ICSGOPlayers_730/GetNextMatchSharingCode. Give it your Steam ID, your game authentication code and the share code of one match you know, and it returns the next share code, or "n/a" when there is no newer match. It only covers the account's own matchmaking games, one code per call, and a share code holds no scores: the stats have to be parsed out of the replay demo.
Professional matches are not in Steam at all. A CS2 esports API holds them indexed by team, player and tournament, so a team's last 50 results is one request.
Valve's CS2 interfaces on the Steam Web API
What each one returns, from Valve's own method catalogue (checked 3 October 2026).
| Interface | What it covers |
|---|---|

| ICSGOServers_730 | Game server and matchmaking status. |
| ICSGOTournaments_730 | Major pick'em layouts and predictions. |
| IEconItems_730 | Item schema and related item data. |
| IGCVersion_730 | Game coordinator version info. |

Frequently asked questions
Steam, GSI, inventories and prices
Something missing? Email support@citoapi.com.
Does Valve have a CS2 API?
Valve's Steam Web API covers accounts, inventories and some game stats. It does not provide pro esports matches or player ratings.
Does Steam still provide CS2 match history?
Steam never had a CS2 match history endpoint: GetMatchHistory exists only for Dota 2. For your own matchmaking games, GetNextMatchSharingCode returns share codes one at a time; pro match history comes from a CS2 esports API.
What is the Steam Web API rate limit?
100,000 calls per key per day under Valve's Steam Web API Terms of Use. Steam answers 429 Too Many Requests when you are throttled.
What is CS2 Game State Integration?
GSI makes a CS2 client send its own game state to a local endpoint, which is useful for overlays of a game you are playing or observing. It does not list other matches.
Can I get CS2 skin prices from Steam?
Steam covers its own market. This API adds third-party marketplaces, sell listings and daily history for each skin.
Does this API read Steam inventories?
No. Fetch the inventory from Steam, then price each item with /cs2/skins.
Is this API affiliated with Valve?
No. CS2 API is operated by Cito API and is not affiliated with Valve Corporation.
