Workspace プランで使える XDC データ API

A pass or fail verdict for a Plugin feed, from fixed rules: the feed is fresh, its answer is positive and its last round is complete. Returns the reasons, warnings such as a single-oracle quorum, the oracle setup of the aggregator, and the other proxies for the same pair with the one to prefer. The feed's answer value is not returned.
