DIA scrapes raw trade data directly from 100+ centralized and decentralized exchanges. There are no third-party aggregators in the data chain. Every price is traceable to specific trades on specific markets, giving developers full transparency into how each data point was derived.
DIA provides a REST API and a GraphQL endpoint. The REST API returns JSON responses for individual token prices, historical data, and batch queries. GraphQL allows more flexible querying, filtering by blockchain, asset type, exchange, and time range. Both are free to access.
DIA sources trade data directly from exchanges rather than aggregating pre-calculated feeds from third-party providers. This means full source transparency: you can verify exactly which exchanges, pairs, and trades contributed to each price. DIA also offers configurable pricing methodologies and onchain oracle deployment for dApps that need prices on the blockchain.
Yes. DIA's API provides historical price data with configurable time ranges and resolution. You can retrieve price histories for backtesting trading strategies, building price charts, conducting research, or generating reports.
Yes. Beyond the free off-chain API, DIA deploys dedicated oracle smart contracts on 65+ blockchains. These onchain oracles power DeFi applications including lending protocols, stablecoins, derivatives platforms, and more. Oracle deployments are configured per customer with custom update triggers and data sources.
DIA applies transparent, configurable methodologies to raw trade data.
