The main difference between the plans is the international data coverage (Level A & B). Also, to get full access to WebSocket, the minimum requirement is the Pro plan.

The trial is designed to help you get started with API and WebSocket by using the specific symbols from all international markets.

To make the API request, replace the symbol and your API key.

https://api.twelvedata.com/time_series?symbol=TEST_SYMBOL&interval=1day&apikey=YOUR_API_KEY

In most cases "apikey=demo" parameter will be sufficient for trial symbols.

Firstly, connect to the WebSocket server.

wss://ws.twelvedata.com/v1/quotes/price?apikey=YOUR_API_KEY

Secondly, send the event with the test symbols.

{

"action": "subscribe",

"params": {

"symbols": "TEST_SYMBOL_1,TEST_SYMBOL_2"

}

}

Remember that you can only establish up to 1 connection and subscribe for up to 8 symbols from the list below. For more detailed WebSocket documentation, check out here. If you still have questions, check the WebSocket FAQ.

All symbols listed here work across all API (including fundamentals) and WebSocket endpoints. Instruments from international markets should include the exchange name after the symbol, separated by the colon SYMBOL:EXCHANGE_NAME.
