name: Cosmos description: >- 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. image: https://kinlane-images.s3.amazonaws.com/shared/apis-json/apis-json-logo.jpg url: https://raw.githubusercontent.com/api-evangelist/cosmos/refs/heads/main/apis.yml version: "0.19" created: "2026-06-13" modified: "2026-06-13" specificationVersion: "0.19" tags: - Blockchain - Cosmos - IBC - Staking - Governance - DeFi - Web3 apis: - name: Cosmos Auth API description: >- Query authentication-related data for accounts on a Cosmos SDK chain, including account information, parameters, and address lookups. image: https://kinlane-images.s3.amazonaws.com/shared/apis-json/apis-json-logo.jpg humanURL: https://docs.cosmos.network/sdk/latest/modules/auth baseURL: https://lcd.cosmos.network tags: - Auth - Accounts - Authentication properties: - type: Documentation url: https://docs.cosmos.network/sdk/latest/modules/auth - type: OpenAPI url: https://cosmos.github.io/cosmos-sdk/openapi.html contact: - FN: Cosmos Developer Support url: https://discord.gg/interchain email: "" - name: Cosmos Bank API description: >- Query account balances, total coin supply, denomination metadata, and denom ownership across a Cosmos SDK chain.
