Overview

The Steam Web API lets developers access public data from the Steam platform, including player profiles, game ownership, achievement stats, and the store catalog. An API key is free and easy to obtain through the Steam developer portal. It is widely used for building gaming dashboards, leaderboards, and Steam profile widgets.

Beginner Tip

All user-specific endpoints require the player Steam ID, a 17-digit number. Users can find their Steam ID in their profile URL or by using a tool like steamid.io.

Available Data

The kind of data this API exposes, based on its documentation. We could not call the endpoint to confirm the exact field names.

match scores and results
team standings
player statistics
schedule and fixtures
Use case: Integrate steam web api documentation data into web and mobile applications

Example Response

Illustrative shape only — we were not able to call this endpoint (it requires credentials or exposes no public sample URL), so the fields below show the kind of data this API returns rather than a recorded response.

Implementation Example

Calls a real endpoint of this API. Replace any placeholder credentials with your own key.

Request
const url = "https://api.steampowered.com/ISteamUser/GetPlayerSummaries/v2/?key=YOUR_API_KEY&steamids=76561198000000000";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
  headers: {
  "X-API-Key": "YOUR_API_KEY"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

Common Errors & Troubleshooting

Generated guidance based on this API's documentation, not observed by us. Treat it as a starting point and check against the provider's own error reference.

Empty or null player data Target player has set their profile to private
Steam respects privacy settings; only public profiles return full data through the API
403 Forbidden Invalid or missing API key
Obtain a free API key at steamcommunity.com/dev/apikey and pass it as the key parameter
Missing game stats Some games are not enrolled in Steam achievements or stat tracking
Use GetSchemaForGame first to see which stats are available for a given app ID before querying them

Metadata Score Breakdown

Estimated from metadata — endpoint not independently tested

This score is estimated from observable metadata — HTTPS support, authentication model, declared CORS, and documentation reachability — because the API requires authentication or exposes no publicly testable endpoint. The five-signal breakdown is only shown for live-tested APIs.
