Cosmos

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.

Cosmos publishes 2 APIs on the APIs.io network: Query API and Service API. Tagged areas include Blockchain, Cosmos, IBC, Staking, and Governance.

The Cosmos catalog on APIs.io includes 2 JSON-LD contexts and 1 Spectral governance ruleset.

Cosmos’ developer surface includes documentation, engineering blog, and 13 more developer resources.
