n8n Market Sentiment Node

n8n-nodes-market-sentiment brings structured stock sentiment data from Adanos into n8n workflows.

It is built for finance automations that need usable outputs instead of raw posts:

• enrich a watchlist from Google Sheets, Airtable, or Notion
• send Slack or Discord alerts when a ticker gets unusually hot
• build daily market recap and newsletter workflows
• compare names like NVDA, AMD, TSLA, or PLTR before the open

What it looks like in n8n

Real editor run with the Enrich Incoming Items operation on a live watchlist:

What the node does

The package exposes a single Market Sentiment node with three operations:

| Operation | Best for | Output | | --- | --- | --- | | Get Stock Snapshot | multi-ticker scans | combined or per-source sentiment snapshots | | Get Trending Stocks | source-specific movers | one item per trending ticker | | Enrich Incoming Items | watchlists and downstream routing | original items plus nested sentiment data |

Supported sources:

• reddit
• x
• news
• polymarket

Install in n8n

1. Open Settings -> Community Nodes.
2. Install n8n-nodes-market-sentiment.
3. Create an Adanos API credential.
4. Add the Market Sentiment node to your workflow.

The node always talks to the official Adanos API at https://api.adanos.org.

Operation guide

1. Get Stock Snapshot

Use this for pre-market scans, manual comparisons, and one-shot ticker lookups.

Inputs:

• tickers: comma-separated list like AAPL,NVDA,TSLA
• sources: any mix of reddit, x, news, polymarket
• days: lookback window, 1 to 90
• outputMode
  • combined: one row per ticker with averaged metrics and source alignment
  • perSource: one row per ticker/source pair
  • raw: raw source payloads grouped into one result item

2. Get Trending Stocks

Use this for “what is moving right now?” workflows.

Inputs:

• source: reddit, x, news, or polymarket
• days: lookback window, 1 to 90
• limit: 1 to 100
• offset
• assetType: all, stock, or etf

3. Enrich Incoming Items

Use this when you already have items coming from Sheets, Airtable, Notion, webhooks, or a Code node.

Inputs:

• tickerField: input field that holds the stock ticker
• targetField: field that will receive the combined snapshot
• sources
• days
• includeSources: include nested per-source breakdowns or not

Typical flow:

Google Sheets -> Market Sentiment -> IF / Slack / AI summarizer

Output shape

Combined snapshot example:

{
  "ticker": "AAPL",
  "companyName": "Apple Inc",
  "averageBuzz": 36.73,
  "averageBullishPct": 63.5,
  "averageBearishPct": 15,
  "averageSentimentScore": 0.16,
  "coverage": 3,
  "sourceAlignment": "divergent",
  "sources": {
    "news": {
      "sourceLabel": "Finance News",
      "buzzScore": 43.9,
      "bullishPct": 80,
      "activity": 25,
      "activityLabel": "mentions",
      "trend": "stable"
    },
    "x": {
      "sourceLabel": "X.com",
      "buzzScore": 66.3,
      "bullishPct": 47,
      "activity": 287,
      "activityLabel": "mentions",
      "trend": "falling"
    }
  }
}

Enriched item example:

{
  "symbol": "NVDA",
  "marketSentiment": {
    "averageBuzz": 38.8,
    "averageBullishPct": 59.5,
    "coverage": 3,
    "sourceAlignment": "mixed"
  }
}

Import-ready example workflows

These are the fastest way to smoke-test the node inside a real n8n instance:

• Manual snapshot validation
• Manual enrichment validation

More workflow templates:

• Daily market recap
• Watchlist enrichment
• Trending alert

After import, select your Adanos API credential on the Market Sentiment node and run the workflow.

Local runtime validation

This package was validated inside a real Docker n8n instance on 2026-03-29.

Validated paths:

• node installs as a community node
• credential loads in the running n8n server
• Manual Snapshot Validation runs in the editor
• Manual Enrichment Validation returns 4 enriched watchlist items in the editor output

Practical note:

• editor/manual execution in the running n8n server works
• standalone n8n execute --id ... can hit a credential/license-state path in some local environments, so use the editor flow for smoke tests

Local development

cd integrations/n8n/market-sentiment-node
npm install
npm run test
npm run typecheck
npm run build

Maintainer release flow

This repo publishes from Git tags through .github/workflows/publish.yml.

Release steps:

1. bump package.json to the target version
2. push main
3. create and push the matching tag, for example v0.1.0
4. let GitHub Actions run npm publish --provenance --access public

The publish workflow fails if the pushed tag does not match package.json exactly.
