gRPC is an open source remote procedure call system initially developed at Google (like [[Golang]]) in 2015 as the next generation of the RPC infrastructure Stubby. [gRPC: Up and Running](https://learning.oreilly.com/library/view/grpc-up-and/9781492058328/) is available at [[O'Reilly]]. In [[Emacs]], it's possible to use [`ob-grpc`](https://github.com/shsms/ob-grpc) with Org-babel to perform calls through [`grpcurl`](https://github.com/fullstorydev/grpcurl).
