CoinGecko

CoinGecko is a cryptocurrency market-data service that aggregates information about cryptoassets, exchanges, non-fungible tokens, and on-chain trading venues. Its public website presents ranked asset and exchange pages alongside market summaries, charts, research, and portfolio tools.^[1]

The service was founded by TM Lee and Bobby Ong on 8 April 2014, according to its corporate history.^[2] CoinGecko serves both a general audience through its website and mobile products and technical users through free and paid data interfaces.^[2][3]

What It Does

CoinGecko organizes cryptocurrency information around assets, exchanges, market categories, blockchain networks, and related products. The website reports prices, trading volumes, market capitalization, exchange listings, token contract information, and broader market indicators.^[1][2] It also provides pages for decentralized-finance categories, derivatives, NFTs, and cryptocurrency treasury holdings.^[1]

The company characterizes its approach as broader than price aggregation because it also tracks community activity, open-source development, events, and on-chain metrics.^[2] That characterization is a description of CoinGecko's own methodology rather than an independently audited statement about data quality. Users therefore need to distinguish values calculated by CoinGecko from values supplied by exchanges or other upstream sources.

Products

The consumer-facing product includes the CoinGecko website, mobile applications, watchlists, portfolio tracking, research reports, and educational material.^[1][2] GeckoTerminal, introduced in the company's chronology in 2021, supplies charts and market information for tokens traded through decentralized exchanges.^[2]

For developers, the CoinGecko API exposes market and on-chain data. Its documentation identifies REST endpoints, WebSocket streams, webhooks, official Python and TypeScript software-development kits, and spreadsheet integrations.^[3] The documentation separates a limited Demo API from paid Pro access, making the service usable for experimentation as well as commercial integration.^[3]

Data And Methodology

CoinGecko's market pages combine data from many trading venues and display derived measures such as market capitalization, fully diluted valuation, dominance, and price changes over multiple periods.^[1] Because cryptocurrency markets trade continuously and the set of listed assets changes, counts and aggregate values shown on the homepage are snapshots rather than stable facts.^[1]

The company says it introduced a Trust Score in 2019 to address misleading exchange-volume reporting.^[2] Its API documentation separately describes coverage of centralized-market data and decentralized-exchange activity, with GeckoTerminal supplying the latter.^[3] Academic literature has also cited CoinGecko as a cryptocurrency-data source, indicating use beyond the company's own publications, although such use does not independently validate every displayed metric.^[4]

Delivery And Pricing

Information is delivered through web pages, mobile applications, downloadable research, and programmable interfaces.^[1][2][3] The API documentation describes key-based access and distinguishes free Demo endpoints from paid Pro endpoints; it also documents streaming and notification mechanisms for applications that require updates without repeatedly polling the REST service.^[3] Exact limits and prices are plan-dependent and should be checked on CoinGecko's current pricing pages rather than inferred from historical descriptions.

History

CoinGecko's published chronology records the launch of its quarterly cryptocurrency report in 2017, a public API and mobile applications in 2018, Trust Score in 2019, portfolio tools in 2020, an enterprise API and GeckoTerminal in 2021, and an NFT floor-price tracker in 2023.^[2] These dates are company-reported milestones. The same chronology says CoinGecko acquired the NFT-data company Zash in 2023 and expanded its on-chain API offering in 2024.^[2]
