The v1 market data endpoints give you access to real-time and historical APY and TVL data across leading lending and staking vaults. You can query the full vault catalog, drill into a single vault, fetch benchmark rates, or pull time-series data for charting and backtesting.
These are legacy v1 endpoints. They are fully supported and maintained. For new integrations, consider using the v2 endpoints.

​
