About this API

Plug the Friendlist API into social-graph tools, community analytics, or anti-fraud heuristics that need to know who connects to whom. Returns a flat list of SteamIDs with the friendship-since timestamp.

Public profiles only — private profiles return an empty list, which lets you detect private-profile fraud signals cheaply.

Steam Friendlist API — FAQ

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.
