Capital.com vs eToro API

The same fields from the Capital.com record and the eToro record, side by side. No winner is picked: which one suits you depends on what you are building.

Independent and unofficialNewest check

Risk warning: CFDs and spread bets are complex instruments and come with a high risk of losing money rapidly due to leverage. You can lose money on these products, and each provider publishes its own loss figure under FCA rules. You should consider whether you understand how they work and whether you can afford to take the high risk of losing your money. Automated and API trading can amplify losses through bugs, connectivity failures and runaway orders.

Instrument topics need no authentication; the private topic needs an Authenticate message first, which carries the user key and API key inside its data object over the open socket, never as a header. A Subscribe message lists topics such as instrument:<instrumentId> or private, with an optional snapshot flag. The AsyncAPI document, the Topics page and the example code agree on that shape. The server sends a single binary frame from time to time as a heartbeat. No connection or subscription limit is given and no reconnection or replay behaviour is described.eToro WebSocket API, AsyncAPI documentchecked
