Using the RPC API

The RPC API allows you to communicate directly with the Calimwero network. The approach is the same as with NEAR RPC, but the RPC endpoint is different.

Access KeysRetrieve information about an account's access keys.
Accounts/ContractsView details about accounts and contracts as well as perform contract calls.
Block/ChunkQuery the network and get details about specific blocks or chunks.
GasGet gas price for a specific block or hash.
ProtocolRetrieve current genesis and protocol configuration.
NetworkReturn status information for nodes and validators.
TransactionsSend transactions and query their status.
Maintenance WindowsQuery the maintenance windows in current epoch for a validator.
