JSON-LD
JSON-LD (JavaScript Object Notation for Linking Data) is a W3C standard for expressing linked data in JSON. It adds lightweight semantics to ordinary JSON so machines can understand what the data means, not just its shape—by mapping keys to globally unique identifiers (IRIs) via a @context. Common features include @id (identity), @type (class), and optional graph constructs (@graph).
Also known as JSON for Linking Data.
Providers that carry JSON-LD 5
These providers' own APIs.json profiles carry JSON-LD as a tag — the provider's statement that the standard is part of what it does. APIs.io has not verified the implementation on this page; the de facto profiles on this site are where that measurement exists. Ordered by Kin Score.
