Marketstack

Retrieve stock market data, end-of-day prices, exchange details, and ticker information.

Overview

Marketstack is a REST API providing real-time and historical stock market data. This tool provides access to the Marketstack API v1 (api.marketstack.com/v1). It supports three resources: End-of-Day Data (get many — closing prices for stocks), Exchange (get — stock exchange details by MIC code), and Ticker (get — stock symbol details). The End-of-Day Data resource supports filtering by latest data, specific date, or date range, plus exchange and sort order filters. Authentication is via API key passed as the access_key query parameter. The free plan uses HTTP only; paid plans support HTTPS.

Output Data

Every result record is merged onto the input item JSON, so upstream fields stay addressable alongside the market data, and binary data is forwarded unchanged.

How many items you get back depends on the resource:

Resource / Operation	Output items
End-of-Day Data: Get Many	Fans out — one item per end-of-day record returned. A query covering three symbols over twenty trading days produces sixty items.
Exchange: Get	One item, carrying the exchange record.
Ticker: Get	One item, carrying the ticker record.

When a query matches nothing at all, a single pass-through item is emitted carrying the input JSON unchanged — so an empty result is visible downstream rather than silently dropping the item.

The record fields are whatever the Marketstack API returns for that endpoint (for end-of-day data that includes the symbol, the date, and the open/high/low/close/volume figures). Reference them downstream by expression, for example {{ $json.close }}.

Usage Examples

• Get the latest closing prices for AAPL and MSFT
• Get end-of-day data for a specific date
• Get end-of-day data for a date range
• Get details about the NASDAQ exchange
• Get details about the AAPL ticker

Example Configuration

Latest closing prices for several symbols:

{
  "type": "marketstack",
  "parameters": {
    "resource": "endOfDayData",
    "operation": "getAll",
    "symbols": "AAPL,MSFT,GOOGL",
    "returnAll": true,
    "filters": {
      "latest": true,
      "sort": "DESC"
    }
  }
}

A month of NASDAQ closes for one symbol, capped at 50 records:

{
  "type": "marketstack",
  "parameters": {
    "resource": "endOfDayData",
    "operation": "getAll",
    "symbols": "AAPL",
    "returnAll": false,
    "limit": 50,
    "filters": {
      "dateFrom": "2026-01-01",
      "dateTo": "2026-01-31",
      "exchange": "XNAS"
    }
  }
}

Closing data for one specific trading day, with the symbol taken from the item:

{
  "type": "marketstack",
  "parameters": {
    "resource": "endOfDayData",
    "operation": "getAll",
    "symbols": "{{ $json.ticker }}",
    "returnAll": true,
    "filters": {
      "specificDate": "2026-03-15"
    }
  }
}

Look up an exchange by its MIC code:

{
  "type": "marketstack",
  "parameters": {
    "resource": "exchange",
    "operation": "get",
    "exchange": "XNAS"
  }
}

Look up a ticker:

{
  "type": "marketstack",
  "parameters": {
    "resource": "ticker",
    "operation": "get",
    "symbol": "AAPL"
  }
}

Error Handling

Mode	Behavior
stop	Halts workflow on first error
continue	Skips failed items, passes successful ones through
errorPort	Routes failed items to Error output port

Tips

Retrieve stock market end-of-day prices, exchange details, and ticker information from the Marketstack API using an API key.

Behavior notes

• Pick exactly one time filter. Latest, Specific Date, and the Timeframe Start/End pair select different endpoints. Latest wins over Specific Date, which wins over the timeframe; and if you use neither Latest nor Specific Date you must supply both timeframe dates or the node errors.
• Ticker takes a comma-separated list. AAPL,MSFT in one node is one API call, and cheaper than three nodes.
• Exchanges are addressed by MIC code, not by name — XNAS for NASDAQ, XNYS for NYSE.
• Dates accept YYYY-MM-DD or full ISO-8601.
• Return All pages the API until it is exhausted, which burns request quota fast on a long timeframe. Set a limit while you are building the workflow.
• The free Marketstack plan is HTTP-only. Paid plans serve the same endpoints over HTTPS.
