API documentation
For using our API, you can retrieve an API-key on the Security page. The secret key is only showed once, so you should save it immediately. The API-key (identifier) is shown in a table. If possible, lock access to a single IP-address, and do not enable more rights than necessary.
The API supports among other things the features to place orders, read the orderbook and to deposit euros or bitcoins. The description of the API and all specific functions are described in the API documentation on GitHub.
Websocket
BL3P offers two public websockets for realtime streaming of executed trades and the current orderbook:
- Trades: wss://api.bl3p.eu/1/BTCEUR/trades
- Orderbook: wss://api.bl3p.eu/1/BTCEUR/orderbook
For questions about our API or websockets you can use our regular support channels.
