The Enterprise connection examples now read the database URI from LANCEDB_URI and the endpoint from LANCEDB_HOST_OVERRIDE, with the API key and region beside them, the convention the rest of the site uses. Without an endpoint they stop rather than fall back to one. Their tests check both. The REST API reference used LANCEDB_URI for the HTTP endpoint and listed and created tables at routes the server does not serve. It now uses LANCEDB_HOST_OVERRIDE, lists tables at /v1/table/, creates `words` from an Arrow IPC stream, and describes it to confirm the write.

[Lance REST Namespace](https://lance.org/format/namespace/) spec
|
|
is an OpenAPI protocol that enables reading, writing and managing Lance tables by connecting
|
|
those metadata services or building a custom metadata server in a standardized way.
|
|
|
|
LanceDB OSS allows you to interface with Lance tables via the REST Namespace.
|
|
LanceDB Enterprise provides an extended REST API with
|
|
additional endpoints for managing tables and data.
|
|
If you have specific needs or questions about the Enterprise REST API Namespace,
|
|
please [contact us](mailto:support@lancedb.com).

## Authentication {#authentication}
|
|

|
<Badge color="red">Enterprise</Badge>
|
|
|
|
All HTTP requests to LanceDB APIs must contain an <u>x-api-key</u> header that specifies a valid API key and
|
|
must be encoded as JSON or Arrow RPC.
|
|
|
|
To authenticate to the Enterprise REST API, you need the endpoint for your deployment and a valid API key for that deployment.
|
|
|
|
### Get your Enterprise credentials {#get-your-enterprise-credentials}
|
|
|
|
1. Obtain the following values from your LanceDB administrator or the LanceDB team that provisioned your Enterprise deployment:
|
|
- an API key
|
|
- your Enterprise REST endpoint
|
|
- your database name, if your deployment uses a private endpoint or `host_override`
|
|
|
|
2. Export those values in your terminal:
|
|
|
|
```bash
|
|
export LANCEDB_API_KEY="<your-api-key>"
|
|
export LANCEDB_HOST_OVERRIDE="https://your-enterprise-endpoint.com"
|
|
export LANCEDB_DATABASE="your-database-name"
|
|
```
|
|
|
|
`LANCEDB_HOST_OVERRIDE` is the endpoint the SDKs take as `host_override`; the
|
|
database name is the part of its `db://` URI after `db://`.
|
|
|
|
3. If your Enterprise deployment is private, connect through the private network endpoint provided for your deployment. For example, Azure Private Link deployments commonly use a private IP or an internal DNS name as the endpoint.
|
|
|
|
### Verify authentication {#verify-authentication}
|
|
|
|
4. Check that you can reach the deployment and list tables:
|
|
|
|
```bash
|
|
curl -X GET "$LANCEDB_HOST_OVERRIDE/v1/table/" \
|
|
-H "x-api-key: $LANCEDB_API_KEY" \
|
|
-H "x-lancedb-database: $LANCEDB_DATABASE"
|
|
```
|
|
|
|
The response lists one page of table names, with a token for the next page when
|
|
there are more.
|
|
|
|
If your deployment endpoint already includes the database host name, you can omit the `x-lancedb-database` header.
|
|
|
|
5. Create a table to confirm write access. Let's call it `words`. A table is
|
|
created from an Arrow IPC stream, which this writes with PyArrow:
|
|
|
|
```bash
|
|
python -c "import pyarrow as pa, sys; t = pa.table({'word': ['hello', 'world']}); w = pa.ipc.new_stream(sys.stdout.buffer, t.schema); w.write_table(t); w.close()" > words.arrow
|
|
|
|
curl -X POST "$LANCEDB_HOST_OVERRIDE/v1/table/words/create" \
|
|
-H "Content-Type: application/vnd.apache.arrow.stream" \
|
|
-H "x-api-key: $LANCEDB_API_KEY" \
|
|
-H "x-lancedb-database: $LANCEDB_DATABASE" \
|
|
--data-binary @words.arrow
|
|
```
|
|
|
|
6. Check that the table has been created:
|
|
|
|
```bash
|
|
curl -X POST "$LANCEDB_HOST_OVERRIDE/v1/table/words/describe" \
|
|
-H "Content-Type: application/json" \
|
|
-H "x-api-key: $LANCEDB_API_KEY" \
|
|
-H "x-lancedb-database: $LANCEDB_DATABASE" \
|
|
-d '{}'
|
|
```
|
|
|
|
That's it -- you're connected! Now, you can start adding data and querying it.
