Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://sommelier-finance.gitbook.io/sommelier-documentation/strategists/protobuf.md). # Protobuf If you are familiar with the use of Protocol Bufffers (protobuf) and gRPC, you can skip this page. > If you are interested in a deeper dive into Protocol Buffers, check out the [official documentation](https://protobuf.dev). In short, protobuf messages define types that can then be generated into any programming language. This allows for a common interface between different languages and platforms and saves time by automatically generating code for message serialization and deserialization and API client/server code. The Steward API is defined by a protobuf package and can be used with a gRPC client. Strategists must generate proto bindings and a client from the Steward API protobuf files for their preferred language using the [protoc compiler](https://grpc.io/docs/protoc-installation/) or [buf](https://buf.build). Please feel free to reach out to the Sommelier team for assistance with generating the necessary bindings in your language of choice if required. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://sommelier-finance.gitbook.io/sommelier-documentation/strategists/protobuf.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
