Monthly billing

When you are on monthly billing, subscriptions are charged on the same date each month every month, for as long as that subscription is active.

You can cancel your account at any time, taking effect at the next payment date.

Annual billing

When you are on annual billing, subscriptions are charged once for the balance of one full year, and will not be charged again (assuming not alterations to the number of users in the Pipedrive account) until the year is over.

Being on the annual billing cycle will give you a discount compared to if you had opted for monthly billing.

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 (10, 30, 200, 500, 700 and 1000 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 while in the development stage and switch to higher limits in production mode.

Price endpoints

With API calls, you can make time series requests that include up to 1,000 most recent records for a given interval. If you require a greater depth of data, you can select an additional rate of historical API calls. And all other endpoints that include prices are requested without any limit.

Reference endpoints

You can access any reference endpoint, for instance, ticker list, exchange list, market status, and conditions. Finazon encourages you to refresh them daily as new information gets populated.

Many applications are powered by historical data that should be accurate and easily accessible. Historical API call is the unit of count when requesting time series data that goes beyond 1,000 records for a given interval. It’s also configurable up to 400 API calls, allowing it to be used for any finance application. And thanks to the infrastructure design of Finazon, historical requests can be executed as fast as fresh data requests.

You can choose the number of API calls that work the best for your case without storing the data, or you can cache mass amounts of data on your side. Caching will help reduce latency, especially around the open/close market where the heaviest traffic occurs.

WebSocket - Trades

Bitfinex Market Data API 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.
