About this API

Avant d'ouvrir une fenêtre de trade Steam, vous voulez savoir : cet utilisateur peut-il trader maintenant, est-il locké, a-t-il Steam Guard, est-il trade-banned ? La Steam Trading API répond à tout cela dans une seule requête.

FAQ

What does trade-eligibility return?

Trade ban status, Steam Guard requirement, lock state, days until trade restriction lifts (if applicable).

Is this real-time?

Yes — every check hits Steam fresh, with short-term caching server-side to absorb rate limits.

How does it differ from the Profile API?

Profile gives you the user's identity. Trade eligibility tells you whether they can trade right now.
