About this API

Bevor du ein Steam-Trade-Window öffnest, willst du wissen: kann dieser User gerade traden, ist er gelockt, hat er Steam-Guard, ist er trade-banned? Die Steam Trading API beantwortet das alles in einem Request.

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.
