List of Pricing Data API projects on Ethereum (2026)

Token API provides instant access to standardized token data including balances, transaction histories, and pricing information across multiple blockchains. The service requires zero setup and delivers real-time token data for wallets and applications.

Witnet Data Feeds provides pre-built price feed contracts deployed across multiple blockchain networks, offering smart contracts access to aggregated cryptocurrency and asset price data without requiring custom data request implementation. The feeds are maintained by the Witnet Foundation and updated at regular intervals through the Witnet oracle network, with each feed exposing standardized interfaces following ERC-2362 specifications for price pair queries. Developers integrate feeds by calling on-chain smart contracts that return latest price values with decimal precision, update timestamps, and query status codes while the underlying data aggregation and validation occurs on the Witnet blockchain.

Codex API provides GraphQL access to blockchain data across multiple networks, indexing transactions, token metadata, and exchange activity for millions of tokens. The system offers real-time and historical data through free and paid tiers for integration into applications.

0x Trade Analytics API is a data service that indexes on-chain trading activity processed through 0x infrastructure. It provides query access to historical trade volumes, pricing, and execution details across supported blockchains for monitoring and reporting purposes. Developers use it to build trade insight dashboards and analytics features into their own applications.

CPAY Market Data is a real-time cryptocurrency pricing and market information service delivered through its own API surface. Developers and businesses query the API to retrieve live price feeds and market information for use in their own applications. It functions independently of CPAY's payment and wallet products, serving as a standalone data access point.
