How to retrieve a list of all market pairs like ETH/BTC using Binance API?

You are looking for the /exchangeInfo public endpoint.

See more at https://github.com/binance-exchange/binance-official-api-docs/blob/master/rest-api.md :

Exchange information

GET /api/v1/exchangeInfo

Current exchange trading rules and symbol information

Resulting symbols array of all coin pairs:

..."symbols": [{"symbol": "ETHBTC","status": "TRADING","baseAsset": "ETH","baseAssetPrecision": 8,"quoteAsset": "BTC","quotePrecision": 8,"orderTypes": [  // These are defined in the `ENUM definitions` section under `Order types (orderTypes)`.  // All orderTypes are optional.],"icebergAllowed": false,"filters": [  // There are defined in the `Filters` section.  // All filters are optional.]}]...

I think it would be easier to create dump of the coin list and place here for new developers

For python users that ended up here after googling "binance api trade pairs":

from binance.client import Clientapi_key = "xxx"api_secret = "xxx"client = Client(api_key, api_secret)exchange_info = client.get_exchange_info()for s in exchange_info['symbols']:    print(s['symbol'])
