Up to 100 namespaces are returned at a time by default, in sorted order (bitwise “C” collation). If the `limit` parameter is set, up to that number of namespaces are returned instead. Whenever there are additional namespaces to return, the response includes `pagination.next`, a token you pass as `paginationToken` to get the next batch of namespaces. When the response has no `pagination`, there are no more namespaces to return.

For guidance and examples, see [Manage namespaces](/guides/manage-data-manage-namespaces).

**Note:** This operation is not supported for pod-based indexes.

```bash curl theme={null}
# To get the unique host for an index,
# see https://docs.pinecone.io/guides/manage-data/target-an-index
PINECONE_API_KEY="YOUR_API_KEY"
INDEX_HOST="INDEX_HOST"

curl "https://$INDEX_HOST/namespaces" \
    -H "Api-Key: $PINECONE_API_KEY" \
    -H "X-Pinecone-Api-Version: 2026-07"
```

`GET /namespaces`

:::code-group
```bash title="cURL"
curl --request GET \
  --url https://{index_host}/namespaces \
  --header 'Authorization: Bearer <token>'

## Authorizations

- `Authorization` (header, string, required) — Bearer authentication header of the form `Bearer <token>`.

## Query Parameters

- `limit` (query, integer) — Max number of namespaces to return per page. Defaults to 100.
- `paginationToken` (query, string) — Pagination token to continue a previous listing operation.
- `prefix` (query, string) — Prefix of the namespaces to list. Acts as a filter to return only namespaces that start with this prefix. Must be ASCII and must not contain the NUL character, matching the namespace names it filters. An empty prefix matches every namespace.

## Headers

- `X-Pinecone-Api-Version` (header, string, required) — Required date-based version header

## Response

- `200` — A successful response
- `400` — Bad request. The request included invalid request parameters.
- `401` — Unauthorized. Possible causes: missing or invalid API key.
- `4XX` — An unexpected error response.
- `5XX` — An unexpected error response.
