What Open Library's access means for an assistant

Public API. A documented public API an agent can call, usually with a key from the service. Open Library's answered HTTP 200 when checked.

To use Open Library from an assistant, connect it where the assistant offers connections (an MCP server, an app or a connector), or point an agent at the published file or API above. What the service returns, and on what terms, is set by Open Library.
