Not every project needs a paid subscription on day one. A free stock market API without an API key is perfect for prototypes, student projects, widgets and testing integrations before going live.

curl "https://api.marketapi.app/v1/free/prices/latest?symbols=EURUSD,XAUUSD"No registration, no key. The response has the same structure as the paid API, so upgrading later only means adding an Authorization header.
What the free tier includes
- Delayed prices for a selection of popular symbols.
- Fair-use limits per minute and per day, so the service stays fast for everyone.
- The same JSON format and status fields as the full API.
Great uses for a free market data API
- Website tickers and "price of gold today" widgets.
- Learning projects: charts, alerts, spreadsheets.
- Integration tests in CI pipelines.
When to upgrade
Move to a key when you need live prices, historical candles, tick data, streaming or higher limits. New accounts receive free credits, and you can pay as you go or choose a monthly plan.
Limits explained
Free requests are limited per minute and per day, per visitor, plus a global limit that protects the service. When you reach a limit, the API answers with HTTP 429 and tells you when to retry, so your code can back off politely. Delayed prices are clearly labelled, so nobody mistakes them for live quotes.

Fetch the free endpoint from your server or build step, cache the result for a minute and render it in your page. Calling it from every visitor's browser wastes your daily allowance; one cached request serves everyone.
Do I need an account?
No account and no key for the free tier. Create an account when you want live data, more symbols, history or higher limits; you start with free credits.
Can I use it commercially?
The free tier is meant for testing, learning and light use. Production apps should use an API key so usage and limits are tied to your account.
More details are on the free stock market API page.
