Perplexity API Module

This reusable workflow allows you to interact with the [Perplexity API](https://docs.perplexity.ai/api-reference/async-chat-completions-post) using the sonar or sonar-pro models. It is designed to be triggered from other workflows and accepts dynamic prompts via input parameters.

Features

- 🧱 Modular: Triggered using Execute Workflow from any other workflow - 📥 Inputs: - SystemPrompt: Set your system-level instruction for the LLM - UserPrompt: The main user prompt for the conversation - 🧠 Uses Perplexity’s chat/completions endpoint - 🔐 Built with API authentication in mind (Bearer token or header auth) - 🔁 Easily extendable for any model in the Perplexity suite

Models supported - sonar - sonar-pro [See full model list and capabilities](https://docs.perplexity.ai/models/model-cards)

Usage

1. Set up your credentials in n8n under HTTP Bearer or Header Auth. 2. Add this workflow as a subworkflow using the “Execute Workflow” node. 3. Pass the desired SystemPrompt and UserPrompt as input variables. 4. Receive the model response in return.
