# POST /entity-types/query/multi

`POST /entity-types/query/multi`

## Headers

- `X-Authenticated-User-Actor-Id` string, uuid, required

## Request body

- GetClosedMultiEntityTypesParams
  - `entityTypeIds` array[], required
    - VersionedUrl[]
  - `includeResolved` 'resolved' | 'resolvedWithDataTypeChildren'
  - `temporalAxes` union, required — Defines the two possible combinations of pinned/variable temporal axes that are used in queries that return [`Subgraph`]s. The [`VariableTemporalAxisUnresolved`] is optionally bounded, in the absence of provided bounds an inclusive bound at the timestamp at point of resolving is assumed. [`Subgraph`]: crate::subgraph::Subgraph
    - object
      - `pinned` object, required
        - `axis` 'transactionTime', required — Time axis for the transaction time. This is used as the generic argument to time-related structs and can be used as tag value.
        - `timestamp` string, date-time, nullable, required
      - `variable` object, required
        - `axis` 'decisionTime', required — Time axis for the decision time. This is used as the generic argument to time-related structs and can be used as tag value.
        - `interval` UnresolvedRightBoundedTemporalInterval, required
          - `end` union, required
