# Get historical lending rates for assets

`GET /api/v1/markets/lend/rate-history`

## Query parameters

- `asset_ids` string, nullable — Optional comma-separated list of asset IDs to filter for. If excluded, values will be returned for all assets.
- `interval` integer — Interval value E.g. for interval buckets of 2h: `interval=2&period=h`
- `period` union, required
  - 'h'
  - 'd'
  - 'w'
  - 'm'
  - 'y'
- `start` integer, required — Start timestamp for interval range (inclusive) Must be provided as unix timestamp (in seconds)
- `end` integer, required — End timestamp for interval range (inclusive) Must be provided as unix timestamp (in seconds)
- `offset` integer — Time series bucket offset
- `limit` integer — Maximum number of time buckets/intervals to return. For responses with multiple series, this limit is applied to each series individually rather than accumulating across series. This is a limit of returned *interval sections*, it is **not** a limit of returned *points*. In other words, `limit=200` will provide 200 time points for a single series. For multi-series responses, each series will also see the exact same set of 200 time points.

## Response `200`

Success response

- AssetRateHistoryObjResponse
  - `data` AssetRateHistory, required — Historical rates for assets
    - `range` object, required — Provides values for the requested range in it's entire width, regardless of page/limit.
      - `start` string, date-time, required
      - `end` string, date-time, required
      - `interval` Interval, required — Interval period & size
        - `value` integer, required
        - `unit` union, required
          - 'h'
          - 'd'
          - 'w'
          - 'm'
          - 'y'
    - `series` object[], required
      - `asset` AssetSpec, required — Provides a unique identifier for an asset for use throughout the Neptune API. IDs are unique across asset domains (contract tokens, native denoms, etc)
        - `id` string, required
        - `group` union, required
          - 'native'
          - 'token'
        - `group_key` string, required
      - `points` object[], required
        - `t` string, date-time, required
        - `v` string, nullable, required
    - `pagination` object, required — Values used for paginating the time series data
      - `next_offset` integer, nullable, required — The offset a client should use to fetch the next page of intervals (so long as limit remains unchanged)
      - `interval_count` integer, required — The total number of intervals/buckets for the provided interval parameters (size, period, start, end)
  - `error` unknown, required
  - `status` integer, required — HTTP status. Successful responses are guaranteed to be < `400`. Conversely, error responses are guaranteed to be >= `400`.
  - `status_text` string, required — HTTP status text

## Other responses

- `500` — Server error response
- `default`
