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 also includes a `pagination_token` that you can use to get the next batch of namespaces. When the response does not include a `pagination_token`, 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: 2026-04"
```

`GET /namespaces`

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