Get a schema

Gets information about API schema. You can use the `versionId` query parameter to get a schema published in an API version. You can use this API to do the following: - Get a schema's metadata. - Get all the files in a schema. This only returns the first file in the schema. The endpoint response contains a link to the next set of response results. - Get a schema's contents in multi-file or bundled format. **Note:** The `versionId` query parameter is a required parameter for API viewers.
