# Weaviate

> Where to find your Weaviate cluster URL + API key and connect them to Nora.

Weaviate is an open-source vector database — useful as the retrieval layer of agent workflows. Nora connects with the cluster URL and an optional API key (anonymous clusters are also supported for dev).

## Where to apply for credentials

| Setup                | Where to find auth                                                         |
| -------------------- | -------------------------------------------------------------------------- |
| Weaviate Cloud (WCS) | [console.weaviate.cloud](https://console.weaviate.cloud) → Cluster details |
| Self-hosted          | The `WEAVIATE_API_KEY` env var on your Weaviate container                  |

For Weaviate Cloud, the cluster URL has the shape `https://<id>.weaviate.network` and the API key is shown once on cluster creation.

## Connect in Nora

<Steps>
  <Step title="Paste the cluster URL">
    Required. Must be HTTPS. RFC1918 / loopback URLs are rejected.
  </Step>

  <Step title="(Optional) Paste an API key">
    For Weaviate Cloud and self-hosted clusters with API-key auth, paste the key. Leave blank for
    anonymous (dev) clusters.
  </Step>

  <Step title="Connect">
    Click **Connect**. Nora calls `GET <url>/v1/meta` (with the Bearer header when a key is set) and reports the Weaviate version on success.
  </Step>
