GetBlock provides fast and reliable access to Cardano nodes via JSON-RPC API. Connect to the Cardano network without running your own infrastructure.
Ogmios is a lightweight bridge to a Cardano node that speaks JSON-RPC 2.0. Over HTTP, it answers stateless request-response calls: ledger and network state queries, transaction submission, and script evaluation. Stateful protocols such as chain synchronization and mempool monitoring run over the WebSocket interface instead.
Every request is an HTTP POST with a JSON-RPC 2.0 body: a method, optional params, and an id. Responses carry the same id and either a result or an error.
