Cosmos gRPC & REST
Cosmos gRPC
HAQQ exposes gRPC endpoints for all the integrated Cosmos SDK modules. This makes it easier for wallets and block explorers to interact with the Proof-of-Stake logic and native Cosmos transactions and queries.
Cosmos HTTP REST (gRPC-Gateway)
gRPC-Gateway reads a gRPC service definition and generates a reverse-proxy server which translates RESTful JSON API into gRPC. With gRPC-Gateway, users can use REST to interact with the Cosmos gRPC service. See the list of supported gRPC-Gateway API endpoints using Swagger here.
