Usage

coin_history_range(coin_id, vs_currency = "usd", from, to, max_attempts = 3)

Arguments

coin_id

(character): ID of the coin of interest or a vector with several IDs. The maximum number of coins that can be queried simultaneously is 30. An up-to-date list of supported coins and their IDs can be retrieved with the supported_coins() function.

vs_currency

(character): name of the reference currency to express the price in. An up-to-date list of supported reference currencies (both fiat and cryptocurrencies) can be obtained with the supported_currencies() function. If an unsupported vs_currency is requested, the call will fail with the respective error message.

from

(POSIXct): timestamp of the beginning of the period of interest (YYYY-MM-DD HH:MM:SS).

to

(POSIXct): timestamp of the end of the period of interest (YYYY-MM-DD HH:MM:SS).

max_attempts

(double, positive): specifies the maximum number of attempts to call the CoinGecko API (e.g., if the first call fails for some reason). Additional attempts are implemented with an exponential backoff. Defaults to 3.

Details

This function returns hourly data for periods of up to 90 days and daily data for periods that are longer than 90 days.

Sometimes, the retrieved data will contain missing values. In such cases, the function will issue a warning and show a list of columns that have missing values.

This function is based on the public CoinGecko API, which has a limit of 50 calls per minute. Please keep this limit in mind when developing your applications.

Value

A tibble with the following columns:
