Interacting with the Casper JSON-RPC API
Casper uses a custom JSON-RPC implementation known as casper-json-rpc that is compliant with the JSON-RPC 2.0 specification. If you are on this page, you are an advanced user wishing to interact directly with a Casper node's JSON-RPC API. You may use Postman or write code to interact with the Casper JSON-RPC API, which is fully compatible with the JSON-RPC 2.0 Specification.
Casper nodes provide the RPC schema on port 8888, followed by rpc-schema:
<HOST:8888>/rpc-schema
To see an example, navigate to a node's RPC schema using a browser.
The Casper client subcommand list-rpcs provides all currently supported RPCs. Here is an example of running the Casper client to list RPCs:
casper-client list-rpcs --node-address <HOST:PORT>
