Overview

Package api implements the general Kaia API functions.

Overview of api package

This package provides various APIs to access the data of the Kaia node. Remote users can interact with Klyatn by calling these APIs instead of IPC. APIs are grouped by access modifiers (public or private) and namespaces (klay, txpool, debug and personal).

Source Files

  • addrlock.go : implements Addrlocker which prevents another tx getting the same nonce through API.
  • api_private_account.go : provides private APIs to access accounts managed by the node.
  • api_private_debug.go : provides private APIs exposed over the debugging node.
  • api_public_account.go : provides public APIs to access accounts managed by the node.
  • api_public_blockchain.go : provides public APIs to access the Kaia blockchain.
  • api_public_mainnet.go : provides public APIs to return specific information of Kaia Mainnet network.
  • api_public_debug.go : provides public APIs exposed over the debugging node.
  • api_public_klay.go : provides public APIs to access Kaia related data.
  • api_public_net.go : provides public APIs to offer network related RPC methods.
  • api_public_transaction_pool.go : provides public APIs having "klay" namespace to access transaction pool data.
  • api_public_tx_pool.go : provides public APIs having "txpool" namespace to access transaction pool data.
  • backend.go : provides the common API services.
  • tx_args.go : provides API argument structures and functions.
