This repository defines the specification for JSON:API, a standardized format for building APIs with JSON. The goal is to minimize bikeshedding and inconsistency by giving developers a well-documented schema for requests and responses. It specifies how to represent resources, relationships, pagination, sorting, filtering, and metadata in a predictable way. Clients and servers that follow the spec can interoperate seamlessly without custom glue code for every new service. JSON:API also emphasizes efficiency, recommending ways to reduce payload size and minimize the number of requests. Over time it has become a widely adopted contract for RESTful APIs, helping teams save time and avoid fragmentation across microservices and third-party integrations.

Features

Standardized request/response format for RESTful JSON APIs
Minimizes requests and payload through compound documents and inclusion
Defines conventions for pagination, sorting, filtering, and linking resources
Supports extensible profiles and optional extensions for custom needs
Promotes discoverability via consistent metadata and link structures
Widely adopted and tool-supported within API ecosystems
