For non-individual users, the delay significantly impacts the user experience, as well as prices and exchange fees. In the United States, end-of-day data (EOD) is not fee-liable, real-time data has the highest exchange fees, and delayed data is a more affordable option in between.

With real-time prices, applications gain the highest level of accuracy and allow you to use them for any business case. However, not all applications will require that degree of performance, so a delayed data feed might be a great alternative with lower fees if it matches your app requirements.

Individual users do not have to pay exchange fees, so data delays come at significantly lower costs.

API calls are the core metric that defines how often you can access Finazon API. This includes but is not limited to requests to reference, price, aggregates, fundamentals, and other endpoints. And thanks to the flexibility of API, each request consumes only one API call. At the start of each minute, the limit will be reset for options with limit (2, 30, 100, 500, 1200, 2500, and 5000 API calls).

Selecting the right amount of API calls largely depends on the intended usage. For instance, simple portfolio tracking applications require fewer requests, while the brokerage terminal has progressive demand and will require unlimited API calls. It’s also possible to make fewer API requests during the development stage and switch to higher limits in production mode.

Sidenote: In the past, we had two options—"API requests" and "Historical API requests." On 25 Jan 2024, we combined them into a single option, "API requests." Now, you can easily choose how many requests you need without worrying about your app's consumption. Configuring datasets has become more friendly and transparent.

WebSocket - Trades

Binance dataset can be configured to stream all trades that are executed in the exchanges. WebSocket trades deliver significantly more frequent data compared with aggregates — frequency that will be noticed when dealing with algorithmic trading and other applications requiring each trade to be processed. The response contains only the last trade price and last trade quantity.

WebSocket - Quotes

To get even more depth of data for the most demanding applications, consider upgrading your dataset with WebSocket Quotes, the best real-time bid/ask (aka Level 1) price and quantity tick level streaming. Level 1 data is a good option for apps that need profound data at the best cost.
