# SearXNG credentials

Documentation for the SearXNG credentials. Use these credentials to authenticate SearXNG in n8n, a workflow automation platform.

You can use these credentials to authenticate the following nodes:

* [SearXNG Tool](/integrations/builtin/cluster-nodes/sub-nodes/n8n-nodes-langchain.toolsearxng.md)

{% hint style="info" %}
**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.

To configure this credential, you'll need an instance of SearXNG running at an URL that's accessible from n8n:

* **API URL**: The URL of the SearXNG instance you want to connect to.

Refer to [SearXNG's Administrator documentation](https://docs.searxng.org/admin/index.html) for more information about running the service.
