# Perplexity with n8n

## Overview

n8n ships a native **Perplexity node** with Agent, Search, and Embeddings resources — all configurable from the visual canvas. Models load dynamically from the API, so the dropdown always reflects the latest options.

:::callout{intent="info"}
**n8n** is a node-based workflow automation platform. It supports both self-hosted and cloud deployments — all examples below work in either. If you're self-hosting, make sure your instance can reach `api.perplexity.ai` outbound. Learn more at [n8n.io](https://n8n.io).
:::

The node supports three resources:

- **Agent** — Third-party models (OpenAI, Anthropic, Google, xAI) with tool-calling and structured output
- **Search** — Raw ranked web results for your own processing
- **Embeddings** — Vector generation for RAG and retrieval pipelines

## Prerequisites

- n8n 2.14.0+ (cloud at [app.n8n.cloud](https://app.n8n.cloud) or self-hosted)
- A Perplexity API key

:::card{title="Get API Key" href="https://console.perplexity.ai/project/keys" icon="key"}
Generate your Perplexity API key from the console.
:::

## Credential Setup

::::steps
:::step{title="Open Credentials"}
In n8n, go to **Settings → Credentials → Add credential**.
:::

:::step{title="Select Perplexity"}
Search for **Perplexity API** and select it.
:::

:::step{title="Add Your Key"}
Paste your API key and save. The node will reference this credential automatically.

## Agent

Use the Agent resource to route through third-party models (OpenAI, Anthropic, Google, xAI) with Perplexity's `web_search` and `fetch_url` tools.

Set **Resource** to `Agent` and configure:

| Parameter               | Description                                                                                 |
| ----------------------- | ------------------------------------------------------------------------------------------- |
| **Model**               | Any model from the dynamic dropdown (e.g., `openai/gpt-5.5`, `anthropic/claude-sonnet-4-6`) |
| **Input**               | Your prompt — supports n8n expressions                                                      |
| **Tools**               | Select `web_search`, `fetch_url`, or both                                                   |
| **System Instructions** | Optional system prompt for the agent                                                        |
| **Response Format**     | Optional JSON schema for structured output                                                  |

## Search

Get raw ranked web results without LLM processing. Set **Resource** to `Search`:

| Parameter         | Description                                 |
| ----------------- | ------------------------------------------- |
| **Query**         | The search query — supports n8n expressions |
| **Recency**       | `day`, `week`, `month`, or `year`           |
| **Domain Filter** | Limit to specific domains                   |
| **Language**      | ISO 639-1 language code                     |
| **Country**       | Two-letter country code                     |

Each result includes `title`, `url`, `snippet`, and `date`.

## Embeddings

Generate vectors for RAG and retrieval pipelines. Set **Resource** to `Embeddings`:

| Parameter | Description                                                        |
| --------- | ------------------------------------------------------------------ |
| **Model** | `pplx-embed-v1-4b` (2560 dims) or `pplx-embed-v1-0.6b` (1024 dims) |
| **Input** | Text to embed — supports n8n expressions                           |

The node also supports contextual embeddings via `POST /v1/contextualizedembeddings` for document-chunk-aware vectors.

## Error Handling

Use n8n's **Error Trigger** workflow or the built-in **Retry on Fail** setting (node settings → Retry on Fail) to handle transient errors:

- **429 Too Many Requests** — add a **Wait** node with exponential backoff before retrying
- **401 Unauthorized** — verify your Perplexity API credential is saved correctly
- **500 errors** — enable Retry on Fail in the node settings
