A look at CoinMarketCap API Solactive integration: how CMC pricing data powers two live cryptocurrency benchmark indices distributed on Nasdaq, Bloomberg, and Reuters.
Introduction
Solactive is a German index provider that calculates, administers, and distributes financial indices across multiple asset classes for ETF issuers, banks, and asset managers worldwide. The company has operated since 2007 and administers thousands of custom indices for institutional clients globally.
In 2019, Solactive entered a formal data partnership with CoinMarketCap to build and operate two cryptocurrency benchmark indices: the CMC Crypto 200 Index and the CMC Crypto 200 ex BTC Index.
The CoinMarketCap API’s Solactive integration is displayed on Solactive's platform, where both index pages explicitly name CoinMarketCap as the data provider and index sponsor. On March 20, 2019, the indices went live on the Nasdaq Global Index Data Service (GIDS), Bloomberg Terminal, Reuters/Refinitiv Eikon, and Germany's Börse Stuttgart. They continue to trade under the Bloomberg tickers CMC200 Index and CMC200EX Index.
This case study examines the partnership’s structure, the evidence on Solactive’s live index pages, where the indices appear today, and what the integration demonstrates for financial institutions building products on CoinMarketCap data.

CoinMarketCap API Integration With Solactive: What Evidence Shows
The partnership between CoinMarketCap and Solactive produced two live indices, both of which carry an explicit data attribution to CoinMarketCap on Solactive's own platform. The evidence spans the original joint press release, the live index pages on solactive.com, independent corroboration from financial news outlets, and real-time quotes on major financial data platforms.
Solactive live index pages — CoinMarketCap named as data provider and sponsor
The data relationship is displayed on Solactive's own index platform. Both index pages carry identical attribution text confirming CoinMarketCap's role as the pricing data source and index sponsor.

"Pricing data for the index is provided by CoinMarketCap, the leading cryptocurrency data provider in the world. [...] The index is sponsored by CoinMarketCap, an independent, unbiased provider of cryptocurrency pricing with history on over 3,000 cryptocurrencies dating back to 2013."
The same text appears on both index pages, which also display the ISIN, Bloomberg ticker, Reuters/Refinitiv RIC, currency, and return type for each index. These pages remain live and accessible today.
What CoinMarketCap API Provides
CoinMarketCap API is the data foundation for both Solactive indices. For an index provider calculating a market cap-weighted benchmark that rebalances quarterly, the specific data requirements map directly to CMC's core endpoint categories:
- Exchange-aggregated pricing: Real-time and historical prices aggregated from 790+ exchanges across 2.4 million assets
- Circulating supply data: Verified circulating supply, total supply, and max supply figures used to determine market cap weights and ranking
- Market cap rankings: Market cap rankings and percentage of total market cap per asset, required to select the top 200 components
- VWAP calculation inputs: Volume-weighted average price (VWAP) inputs from over 200 licensed exchanges per asset
- Historical depth: Historical OHLCV data back to 2010 for backtesting index performance prior to the live date
- Asset metadata: Asset identifiers, symbols, and metadata needed to map CoinMarketCap IDs to index constituents
The API handles over 1 billion calls per month and supports institutional production use cases through its Enterprise plan, which includes custom rate limits, SLA commitments, and commercial licensing. Index providers calculating live financial products on regulated exchanges require this level of operational reliability.

Why CoinMarketCap API
CoinMarketCap's designation as the index sponsor and named pricing data provider for two live Solactive indices reflects its standing as the benchmark data standard in cryptocurrency markets. Here is what makes it the appropriate choice for an institutional index calculation use case.
Conclusion
The CoinMarketCap API’s Solactive integration is one of the most clearly documented data partnerships in the cryptocurrency industry. The evidence is on display on Solactive's own platform, where both live index pages name CoinMarketCap as the pricing data source and index sponsor in formal product documentation. The indices trade in real time on Nasdaq, Bloomberg, Reuters, and Börse Stuttgart, and the same data relationship extends downstream to the NAV calculations for institutional crypto ETPs on the SIX Swiss Exchange.
For financial institutions, index providers, and asset managers considering cryptocurrency benchmark products, the Solactive and CoinMarketCap partnership demonstrates what a production-grade institutional integration looks like. It features two formally named parties, a documented data flow, live tradeable products on regulated financial platforms, and an ongoing operational relationship that has been running since 2019.
CoinMarketCap API is available across free and paid tiers at coinmarketcap.com/api. Whether the use case is a cryptocurrency benchmark index, an institutional crypto ETP, or a market cap-weighted analytics product, CMC provides the pricing depth, supply methodology, and operational scale to power it.
