Historical Cryptocurrency Prices for Active and Delisted Tokens!

This is a modification of the original crypto package by jesse vent. It is entirely set up to use means from the tidyverse and provides tibbles with all data available via the web-api of coinmarketcap.com. It does not require an API key but in turn only provides information that is also available through the website of coinmarketcap.com.

It allows the user to retrieve

• crypto_listings() a list of all coins that were historically listed on CMC (main dataset to avoid delisting bias) according to the CMC API documentation
• crypto_list() a list of all coins that are listed as either being active, delisted or untracked according to the CMC API documentation
• crypto_info() a list of all information available for all available coins according to the CMC API documentation
• crypto_history() the most powerful function of this package that allows to download the entire available history for all coins covered by CMC according to the CMC API documentation
• crypto_global_quotes() a dataset of historical global crypto currency market metrics to the CMC API documentation
• fiat_list() a mapping of all fiat currencies available via the CMC WEB API (note: since v2.0.0 only USD is available)
• exchange_list() a list of all exchanges available as either being active, delisted or untracked according to the CMC API documentation
• exchange_info() a list of all information available for all given exchanges according to the CMC API documentation

Since version 3.0.0 the package also draws on CoinGecko as a second, independent source, again without an API key. The cg_* functions return tibbles with the same column names as their CMC counterparts:

• cg_list(), cg_listings(), cg_info() the CoinGecko coin universe (including dead coins via cg_id_mapping()), a full current snapshot with prices, and coin metadata
• cg_history() and cg_history_by_id() daily close, volume and market cap for the full lifetime of each coin (USD), plus daily OHLC for the last 30 days
• crypto_crosswalk() links CoinMarketCap ids to CoinGecko ids, including dead coins, from the weekly Open Crypto Pricing crosswalk (CC BY 4.0)

See vignette("coingecko-integration") for a walkthrough and vignette("cg-vs-cmc") for matching and reconciling the two sources.

Changelog

Version 3.0.0 (October 2026)

CoinGecko becomes a second data source (cg_* functions), and crypto_crosswalk() links CoinMarketCap and CoinGecko ids. crypto_listings() now returns all coins and their prices by default (limit = NULL, quote = TRUE); the old default limit = 5000 cut every historical day at rank 5,000 since 2021. crypto_info() and exchange_info() use a column allowlist and no longer break when CMC adds fields. See NEWS for the full list.

Version 2.0.2/2.0.3/2.0.4/2.0.5 (September 2025)

Slight change in api output broke crypto_info() (new additional column). Fixed.

Version 2.0.1 (July 2024)

Slight change in api output broke crypto_info(). Fixed.

Version 2.0.0 (May 2024)

After a major change in the api structure of coinmarketcap.com, the package had to be rewritten. As a result, many functions had to be rewritten, because data was not available any more in a similar format or with similar accuracy. Unfortunately, this will potentially break many users implementations. Here is a detailed list of changes:
