A comparison of JSON-RPC and REST, clarifying that JSON-RPC is a protocol organized around actions while REST is an architectural philosophy centered on resources. Key differences include transport agnosticism (JSON-RPC) vs. HTTP-native caching and discoverability (REST). REST dominates at 92% of APIs in 2025 and suits public-facing, resource-oriented APIs, while JSON-RPC fits complex batch operations and action-heavy use cases like MCP and language server protocols. The future likely involves both coexisting rather than one replacing the other.
