How to get a Tiingo API key

Tiingo gives every account an API token on a dedicated page. Pass it as token or in an Authorization: Token … header.

Before you start

  • An email address

Create your Tiingo API key

  1. 1

    Sign up

    Create a free account at tiingo.com and confirm your email.

  2. 2

    Open the token page

    Open the account menu and choose API → Token, or go to tiingo.com/account/api/token.

  3. 3

    Copy the token

    Copy the token shown. Save it as TIINGO_API_TOKEN.

  4. 4

    Regenerate if exposed

    The same page lets you reset the token; old copies stop working immediately.

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 "Authorization: Token $TIINGO_API_TOKEN" \
  "https://api.tiingo.com/tiingo/daily/aapl/prices?startDate=2025-01-02&endDate=2025-01-10"
A JSON array of bars means the token works. 401 means a wrong token.

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 Tiingo (Pro).

  2. 2

    Paste each value

    Paste the values into TIINGO_API_TOKEN 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.

TIINGO_API_TOKEN=paste-your-value-here
.env for local runs

Troubleshooting

429 / limit message
Hourly or daily request limit, or the monthly unique-symbol cap. Cache and slow down.
Empty array
No trading in the range, or a wrong ticker (Tiingo uses lowercase, brk-b).

Frequently asked questions

Can I use Tiingo commercially on the free plan?

No. The free and Power plans are for internal, personal use; redistribution needs a commercial licence.

Turn Tiingo data into a tested strategy

Backtest an idea in the browser, then export Python whose live loop reads candles straight from Tiingo with your own key.

  • Generated Tiingo candle fetcher, closed bars only
  • An AI copilot that writes and revises the rules
  • Pair it with Alpaca, Binance, OANDA or another broker

How the Tiingo API works

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