# Cosmos

**Canonical:** https://apis.io/providers/cosmos/  
**APIs profiled:** 2

Cosmos is an interoperable blockchain ecosystem providing a modular framework (Cosmos SDK) for building sovereign, high-performance application-specific blockchains. The Cosmos SDK exposes LCD (Light Client Daemon) REST APIs on port 1317, generated automatically via gRPC-gateway from Protobuf definitions. These endpoints cover accounts, balances, transactions, governance proposals, staking delegations, IBC transfers, minting, distribution, and ABCI app data. The Cosmos Hub (cosmoshub-4) is the flagship chain; the same API surface is shared by 150+ chains in the ecosystem.
