Before you start

  • An email address (no card for the free plan)

Create your Financial Modeling Prep API key

  1. 1

    Sign up

    Create an account at financialmodelingprep.com and verify your email.

  2. 2

    Open the dashboard

    Go to Dashboard (site.financialmodelingprep.com/developer/docs/dashboard).

  3. 3

    Copy the API key

    Copy the key at the top of the page; save it as FMP_API_KEY. The usage block below shows today’s calls.

Test the key

Before wiring the key into a strategy, make one request by hand. It separates “the key is wrong” from “my code is wrong”.

curl -s "https://financialmodelingprep.com/stable/historical-price-eod/full?symbol=AAPL&apikey=$FMP_API_KEY" | head -c 300
A JSON array of daily bars means the key works; Invalid API KEY means it does not.

Add the key to your AlgoGP project

  1. 1

    Open your project’s APIs & keys tab

    Open the strategy project, select APIs & keys, and under Platforms choose Financial Modeling Prep (Pro).

  2. 2

    Paste each value

    Paste the values into FMP_API_KEY and click Save. Values are encrypted at rest, never shown again and never written into code or exports.

  3. 3

    Run locally with the same names

    Exported projects read the same names from .env (copy .env.example). Keep .env out of version control.

FMP_API_KEY=paste-your-value-here

How the Financial Modeling Prep API works

AlgoGP is not affiliated with Financial Modeling Prep. Menus get renamed from time to time; if a label differs, the official documentation has the current path.
