NaLU AIInstall

Summary

Sends an agent message and the user's reply to the NaLU AI service to analyze conversational context, such as whether the user is making a counter-proposal (e.g. changing installments vs. currency amounts). Returns the service's JSON response as-is.

Inputs

• agent_message (required) — The message the agent sent, e.g. an offer like "Posso parcelar em 20x de R$100. Topa?".
• user_reply (required) — The user's reply to that message, e.g. "Bora em 48?".

Output shape

One JSON object per input item, containing the parsed response from the NaLU AI endpoint (POST https://naluai.dev/v1/extract/reply). Each output is paired to its input item.

The response fields are not defined in the node source; they come directly from the API. Requires the naluAiApi credential. The Language parameter is not sent for this operation. If Continue On Fail is enabled, a failed item returns {error: message} instead of stopping the workflow.

Examples

Example 1: Interpret a customer's counter-offer in a debt negotiation chatbot.

Validator: Validate Reply Context; Agent Message: "Posso parcelar em 20x de R$100. Topa?"; User Reply: "Bora em 48?"

Example 2: Map chat history fields to the validator using expressions.

Agent Message: {{ $json.lastBotMessage }}; User Reply: {{ $json.userText }}
