Pull real-time and historical stock market data directly into your agent workflows

DatabaseAnalyticsFinanceDeveloperAutomation

Marketstack is a REST API that delivers real-time, intraday, and historical stock market data for 170,000+ tickers across 70+ global exchanges — returning everything in clean JSON that any system can consume. Connect it to Actionist and your agents can pull daily portfolio closes, intraday price snapshots, dividend and split history, benchmark index data, and full ticker and exchange metadata on a schedule or on demand — feeding financial models, populating CRM records, generating market-commentary content, and maintaining compliance logs without anyone touching a finance terminal.

Daily portfolio valuation at market close

When the market-close calendar event fires, the agent fetches closing prices for all 50 portfolio holdings, writes them to the valuation sheet in Google Sheets with calculated P&L, fetches benchmark index closes for comparison, and posts a summary card to the #finance Slack channel — all before the analyst would have finished pulling the first ticker manually.

What your agent runs for you

  • Sales
    20 min / week
    Manual market research before account calls

    Sales Agent
    0 min
    Agent enriches accounts with live market data automatically

    When a new enterprise account is added to the CRM, the agent looks up the ticker, fetches the current price, and writes market context to the deal record before the rep makes the first call.

  • Marketing
    45 min / week
    Manual market data collection for content

    The content team manually pulls index returns from finance sites, formats the numbers into a recap, and QA-checks the figures before publication — every Friday afternoon.

    Marketing Agent

  • Customer Support
    25 min / week
    Manual coverage lookup for each support ticket

FAQs

Questions about Marketstack + Actionist

How does Actionist connect to Marketstack?
Go to the Apps tab, find Marketstack, and click Connect. You will need a Marketstack API access key — log in to your Marketstack account (marketstack.com), navigate to the Dashboard, and copy your API key. Paste it into the API key field in Actionist and click Test Connection. Actionist runs a lightweight read call to the end-of-day endpoint to confirm the handshake before any agent tasks run.
Do I need a specific Marketstack plan or permissions for Actionist to work?
Yes. Your API key inherits the permissions of your Marketstack plan. A Free plan key only reaches end-of-day data and the last 12 months of history. A Basic or higher key unlocks intraday data. Professional and above add real-time quotes updated every 60 seconds, plus advanced endpoints like indices, commodities, and ETFs. Make sure the key you paste into Actionist matches the plan that covers the data types your agents need — otherwise calls to premium endpoints will return a 401 error.
Can Actionist trigger actions the moment a stock price changes?
Marketstack is a REST polling API — it does not offer webhooks or push-based event streams. Actionist agents schedule periodic calls to fetch the latest end-of-day or intraday data on a cadence you set (e.g., daily at market close, or hourly during trading hours). If you want to react to a price crossing a threshold, configure a scheduled agent task that fetches the current quote and compares it against your target — the agent fires downstream actions when the condition is met.
How does API call counting work and how do I avoid hitting my Marketstack quota?
Each ticker symbol in a Marketstack API request counts as one API call. A query for five tickers uses five of your monthly quota. Actionist agents batch-fetch tickers where possible to minimize call count. API errors do not count against your quota. Marketstack sends automatic alerts at 75%, 90%, and 100% of your monthly limit, and overages are charged per-call at a rate that decreases on higher plans. If your agents run frequent multi-ticker sweeps, monitor consumption in the Marketstack dashboard and upgrade if you consistently approach your ceiling.
Which stock exchanges and ticker symbols does Marketstack cover?
Marketstack covers 170,000+ stock tickers across 70+ global stock exchanges, including NASDAQ, NYSE, London Stock Exchange, Tokyo Stock Exchange, and dozens more. U.S. exchange data is sourced from Tiingo, Inc. Coverage spans equities, ETFs, market indices, and — on higher plans — bonds and commodities. If you need a specific ticker or exchange, verify it is in the Marketstack supported list via the /tickers or /exchanges endpoints before building an agent workflow around it.
How far back does Marketstack historical data go?
Marketstack provides up to 30 years of end-of-day historical data on its highest-tier plans, and at least 12 months on the Free plan. Intraday data at 1-minute resolution is available from the intraday endpoint on Basic plans and above. Historical depth varies by plan: Free gives 1 year, Basic 5 years, Professional 10 years, and Business/Enterprise up to 30 years. Specify date ranges using the date_from and date_to parameters in your agent's fetch action.
What are the most common ways finance teams use Marketstack with Actionist?
Common Marketstack agent patterns for finance teams: (1) daily EOD sweep — fetch closing prices for a watchlist at 6 PM and push them to a Google Sheets model; (2) weekly portfolio valuation — pull end-of-day data for all held tickers every Friday and update a Notion portfolio tracker; (3) index benchmark comparison — fetch S&P 500 index data alongside individual holdings to produce a vs-benchmark report in Slack; (4) earnings-window data pull — scheduled agent tasks that increase fetch frequency around a company's earnings date to capture intraday volatility.
Do I need a separate data pipeline to get Marketstack data into my spreadsheets or reports?
Marketstack returns all data as lightweight JSON, which Actionist can parse, filter, and pass downstream without any transformation middleware. Your agent can extract specific fields — open, high, low, close, volume, adjusted close — and write them directly to Google Sheets cells, append rows to a database, format them into a Slack digest, or use them as inputs to a financial model in Notion. No separate ETL pipeline is needed for the standard read-and-distribute workflow.
