# Apicurio

Apicuro supports the following versions of Confluent's API:

* Confluent Schema Registry API v6
* Confluent Schema Registry API v7

{% hint style="success" %}
Only one Schema Registry connection is allowed.

Name must be schema-registry.

See [JSON schema](/latest/deployment/configuration/agent/overview.md#json-schema-support) for support.

Environment variables are supported; escape the dollar sign

```yaml
sslKeystorePassword:
  value: "\${ENV_VAR_NAME}"
```

{% endhint %}

Set the schema registry URLs to include the compatibility endpoints, for example:

```bash
http://localhost:8080/apis/ccompat/v6
```

{% code title="provisioning.yaml" %}

```yaml
confluentSchemaRegistry:
  - name: schema-registry
    tags: ["tag1"]
    version: 1      
    configuration:
      schemaRegistryUrls:
        value:

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.lenses.io/latest/deployment/configuration/agent/automation/schema-registries/apicurio.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
