How to Get a NewsAPI Key (Free Developer Plan) – Guide

Before you start

1
Register
Go to newsapi.org/register, enter your name, email and a password, and accept the terms.
2
Copy your key
Your API key is shown right after registration and on your Account page. Save it as NEWS_API_KEY.
3
Set a news query
In AlgoGP set news_query in config.json (e.g. bitcoin OR btc) and enable filters.sentiment with the news source. Backtests use the keyless archive; the key adds NewsAPI headlines when live.py runs.

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-Api-Key: $NEWS_API_KEY" \
  "https://newsapi.org/v2/everything?q=bitcoin&pageSize=3&sortBy=publishedAt"

"status":"ok" with articles means the key works; apiKeyInvalid means it does not.

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 NEWS_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.

NEWS_API_KEY=paste-your-value-here

.env for local runs

rateLimited: More than 100 requests today on the free plan.
parameterInvalid (date): A from date older than your plan allows.

Yes, the Developer plan key is free for development with 100 requests per day.

Combine price rules with news and sentiment filters, test them point-in-time so nothing leaks from the future, and export the code.

Free plan, no card required.
