# APIs

Powered by a cutting-edge microservice-driven architecture, Wetez provides timely, accurate and stable APIs, Wetez APIs, for dApps, developers and general users. Wetez APIs currently supports blockchain networks like Ethereum, Polygon, Solana, Arbitrum and also the Cosmos-eco networks, and is gradually covering a wider range of blockchain networks starting with the Cosmos Ecosystem.
