Covalent API

Blockchain · Data Analytics

Covalent provides a Unified API that abstracts blockchain data across more than 100 networks under a single, consistent API structure. Rather than building separate integrations for Ethereum, BNB Chain, Polygon, Avalanche, Arbitrum, Optimism, and dozens of other EVM and non-EVM chains, Nigerian developers can use one API with one key and one endpoint pattern to query any supported network.

Covalent API Highlights

Covalent API is verified for developer integrations in Nigeria and across African markets, providing documented endpoints, sandbox testing, and developer support.
