How to get a Finnhub API key

Before you start

An email address

Create your Finnhub API key

1
Register
Sign up at finnhub.io.
2
Copy the key
The API key is on your dashboard (finnhub.io/dashboard). Save it as FINNHUB_API_KEY.

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 -H "X-Finnhub-Token: $FINNHUB_API_KEY" "https://finnhub.io/api/v1/quote?symbol=AAPL"

A JSON quote with c (current price) means the key works.

Add the key to your AlgoGP project

1
Open your project’s APIs & keys tab
Open the strategy project and select APIs & keys in the workspace tabs.
2
Paste each value
Paste the values into FINNHUB_API_KEY and click Save. Values are encrypted at rest, never shown again and never written into code or exports.
3
Run locally with the same names
Exported projects read the same names from .env (copy .env.example). Keep .env out of version control.

.env for local runs
