# Lending Rate History

> Coming soon, upon request — this feature is turned on for your tenant by the Aurea team. [Contact us](https://www.aureahub.com/contact)

The pool's yearly rate over the last 90 days, for a chart.

## Overview

- Up to 30 points, one every 3 days, oldest first, for the first lending chain of the network (Gnosis Chain first; [Chain and Wallet](https://docs.aureahub.com/docs/guide-lending.md)).
- `timestamp` in Unix seconds, worked out from the chain's block times, so approximate; `apy` in percent, compounded, rounded to two decimals. A point that cannot be read is left out.
- No lending chain on the network: `"history": []`.
