Inputs

Field	What it does	Type
`source`	Which book catalog to search. Open Library is the reliable keyless source. Google Books returns descriptions and prices but its keyless mode shares one global Google project whose daily quota is usually exhausted (HTTP 429) - supply your own free API key below, or the actor falls back to Open Library automatically. Output is normalized identically for both.	string
`query`	Keywords to search for, e.g. "clean code", "the hobbit", or "isbn:9780132350884". Required.	string
`googleApiKey`	Optional. Only used when Source = Google Books. Keyless Google Books calls are metered against one shared anonymous Google project used by the whole internet, and its daily quota is usually already spent (HTTP 429 from every IP - a proxy does not help). A free key from console.cloud.google.com (enable the Books API, create an API key) puts the requests on your own quota. Leave empty to use Open Library instead.	string
`maxItems`	Maximum number of unique books to return. Results are paginated automatically and deduplicated by ISBN (or title + author).	integer
`notionConnector`	Optional. Write each result as a page into your Notion when the run finishes. Authorize a Notion connector once in Settings → API & Integrations → MCP connectors, then pick it here. Leave empty to skip (default) — results are always saved to the dataset regardless.	string
`notionParentId`	Optional. The Notion data source ID of the database to write into (only used if a Notion connector is set). Leave empty to create the pages privately in your workspace instead.	string

What you get
