About this API

Antes de abrir una ventana de trade de Steam, quieres saber: ¿puede este usuario hacer trade ahora, está lockeado, tiene Steam Guard, está trade-banned? La Steam Trading API responde a todo esto en una sola solicitud.

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.
