HTTP Request Tool#

The HTTP Request tool works just like the HTTP Request node but it allows you to use it with an AI agent as a tool to collect information from a website or API.

On this page, you'll find a list of operations the HTTP Request node supports and links to more resources.

Credentials

Refer to HTTP Request credentials for guidance on setting up authentication.

Parameter resolution in sub-nodes

Sub-nodes behave differently to other nodes when processing multiple items using an expression.

Most nodes, including root nodes, take any number of items as input, process these items, and output the results. You can use expressions to refer to input items, and the node resolves the expression for each item in turn. For example, given an input of five name values, the expression {{ $json.name }} resolves to each name in turn.

In sub-nodes, the expression always resolves to the first item. For example, given an input of five name values, the expression {{ $json.name }} always resolves to the first name.
