# Get Index Status

> Check how far the historical index trails the chain

Reports whether the market has indexed history and how far behind the chain the index currently sits. Use it to decide whether [Get Market History](/endpoints/external-securities-lending/get-history) is trustworthy before charting it, and to tell "no activity" apart from "not indexed yet".

Like the history endpoint, an indexing outage returns `200` with `available: false` rather than an error.
