# Lending Market Interest Rates

> Daily supply and borrow rates for one token in one lending market, as decimals (0.05 is 5%), weighted by the supply and borrow balances they apply to, with those weights in USD. Each series is one market token, keyed by protocol, product, chain, market and token. Many series per market, so name the series you need.

One row per token in a lending market with interest rates, keyed by protocol, product, chain, market and token: the market and token, the parent protocol and product, chain and the mapped protocol, project and network records. The id is the series key of the lending-market-interest-rates timeseries model.

| | |
| - | - |
| Access | Lending-protocols-dataset |
| Tabular model | `lending-market-interest-rates`: primary key `id` |
| Timeseries model | `lending-market-interest-rates`: intervals `1d`, series key `id` (Lending Market Interest Rate ID), series must be named (up to 20 per call) |

## Metrics

8 metrics. Use the `Field` value in `selections`; every point starts with the timestamp and continues in this order.

| Field | Name | Type | Unit | Description |
| - | - | - | - | - |
| `borrowAPR` | Borrow APR | float64 | | Borrow-weighted borrow APR, as a decimal. |
| `supplyAPR` | Supply APR | float64 | | Supply-weighted supply APR, as a decimal. |
| `borrowAPY` | Borrow APY | float64 | | Borrow-weighted borrow APY, as a decimal. |
| `supplyAPY` | Supply APY | float64 | | Supply-weighted supply APY, as a decimal. |
| `borrowAPYStdDev` | Borrow APY Standard Deviation | float64 | | Weighted standard deviation of the borrow APY over the day. |
| `supplyAPYStdDev` | Supply APY Standard Deviation | float64 | | Weighted standard deviation of the supply APY over the day. |
| `borrowedUSD` | Borrowed (USD) | float64 | | Borrows in USD, the weight behind the borrow rates. |
| `suppliedUSD` | Supplied (USD) | float64 | | Supply in USD, the weight behind the supply rates. |

## Columns

Use the `Field` value in `selections`, `sortBy`, and as the base of a filter parameter (`Field` plus one of its `Filters` suffixes).

| Field | Type | Filters | Sort | Description |
| - | - | - | - | - |
| `id` | string | `Eq`, `IsOneOf` | | The series key of the lending-market-interest-rates timeseries model, the parent slug, product slug, chain, market key and token key, joined with underscores. (primary key) |
| `name` | string | `Eq`, `IsOneOf`, `Contains` | default | The display name of the series, the market name and token symbol. |
| `slug` | string | `Eq`, `IsOneOf` | yes | The parent protocol's project slug, the slug used for the same protocol across the API. |
| `parentSlug` | string | `Eq`, `IsOneOf` | yes | The parent protocol's short name, the id in lending-protocols (aave). |
| `productSlug` | string | `Eq`, `IsOneOf` | | The product or version within the parent protocol (aave-v3). |
| `chain` | string | `Eq`, `IsOneOf` | | The short name of the chain the market lives on (ethereum, bnb, solana). |
| `marketID` | string | `Eq`, `IsOneOf` | | The market or pool address; null when the protocol does not label markets. |
| `marketName` | string | `Eq`, `IsOneOf`, `Contains` | | The market display name. |
| `marketType` | string | `Eq`, `IsOneOf` | | The market type where the protocol distinguishes one (for example core, pooled or credit\_vault); null otherwise. |
| `tokenAddress` | string | `Eq`, `IsOneOf` | | The token contract address (the mint address on Solana); null when unlabeled. |
| `tokenSymbol` | string | `Eq`, `IsOneOf`, `Contains` | yes | The token's ticker symbol. |
| `protocolSlug` | string | `Eq`, `IsOneOf` | | The slug of the protocol record mapped to the product; null when unmapped. |
| `protocolName` | string | `Eq`, `IsOneOf` | | The name of the protocol record mapped to the product; null when unmapped. |
| `projectID` | string | `Eq`, `IsOneOf` | | The identifier of the parent protocol's project record. |
| `networkID` | string | `Eq`, `IsOneOf` | | The chain's networkID in the blockchains model; null when unmapped. |
