**Searching these docs as an agent**

Ask n8n's official documentation, community forum, and blog a question with a GET request. No authentication needed.

`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.

## What to do if your operation isn't supported

If this node doesn't support the operation you want to do, you can use the [HTTP Request node](/integrations/builtin/core-nodes/n8n-nodes-base.httprequest.md) to call the service's API.

You can use the credential you created for this service in the HTTP Request node:

1. In the HTTP Request node, select **Authentication** > **Predefined Credential Type**.
2. Select the service you want to connect to.
3. Select your credential.

Refer to [Custom API operations](/integrations/builtin/custom-api-actions-for-existing-nodes.md) for more information.
