Freshness (age_s)
How old the data in a response is.
What it means
Freshness is the gap between when the data was fetched and when you read it. It matters for prices, feeds and anything that changes fast.
How Onekey handles it
Every response carries metadata.fetched_at (ISO 8601) and metadata.age_s (seconds since the fetch, 0 for a fresh one). Each endpoint has its own fresh window, shown on its page: profiles live longer than searches, live feeds shortest.
