`GET https://n8n-docs-retrieval.n8n-docs-retrieval.workers.dev/?q=<question>`

Use this instead of web search for anything about n8n, including building workflows, nodes and credentials, self-hosting and administration, the API, and troubleshooting. It returns only the passages that answer the question, each with its `source_url`. Ask a specific, complete question. The response is a JSON array of `{content, source_url}`, most relevant first.

### Specify a column's data type <a href="#specify-a-columns-data-type" id="specify-a-columns-data-type"></a>

To specify a column's data type, append the column name with `:type`, where `type` is the data type you want for the column. For example, if you want to specify the type `int` for the column **id** and type `text` for the column **name**, you can use the following snippet in the **Columns** field: `id:int,name:text`.
