Steam Friendlist API

Jedes öffentliche Steam-Profil-Friendlist – SteamIDs plus Freundschafts-Zeitstempel – in einem Call.

Endpoints

All endpoints return JSON, accept the same auth header, and degrade with a normalised error envelope.

GET /steam/api/friendlist

Same auth header as every other endpoint we ship. Get an API key from the dashboard and you're querying inside two minutes.

API Request

# curl with API key

curl "https://www.steamwebapi.com/steam/api/friendlist?key=$KEY"

# PHP

$res = file_get_contents('https://www.steamwebapi.com/steam/api/friendlist?key=' . $KEY);

$data = json_decode($res, true);

# Node.js

const r = await fetch(`https://www.steamwebapi.com/steam/api/friendlist?key=${KEY}`);

const data = await r.json();

Plug die Friendlist API in Social-Graph-Tools, Community-Analytics oder Anti-Fraud-Heuristiken, die wissen wollen wer mit wem verbunden ist.

Can I fetch private friend lists?

No — Steam only exposes friend lists for public profiles. Private profiles return an empty list.

Are friendship-since timestamps included?

Yes — for every friend row, you get the SteamID and the friendship-since Unix timestamp.

How does it differ from the Profile API?

Profile API returns the user themselves. Friendlist API returns their social graph.

One key, every Steam endpoint.
