# Index Info

> Returns some information about the index; such as `vectorCount`, `indexSize`, `dimension` and `similarityFunction`.

Info will be updated eventually, so it might take some time to see the effect of changes in this endpoint.

## Request

This request doesn't require any additional data.

## Response

<ResponseField name="vectorCount" type="number" required>
  The number of vectors in the index, that are ready to use.
</ResponseField>

<ResponseField name="pendingVectorCount" type="number" required>
  The number of vectors in the index, that are still processing and not ready to
  use.
</ResponseField>

<ResponseField name="indexSize" type="number" required>
  The total size of the index, in **bytes**.
</ResponseField>

<ResponseField name="dimension" type="number" required>
  Dimension of the vectors.
</ResponseField>

<ResponseField name="similarityFunction" type="string" required>
  Name of the similarity function used in indexing and queries.
