Node API is Ankr's product term for the gateway empowering your projects to interact with blockchains. Node API supports `HTTPS` and `WSS` protocols for RPC and REST types of requests for blockchain communication.
Node API contains the following method collections:
Standard — a collection of standard methods to connect to a node for interaction with on-chain data and sending different types of transactions to the network.
Trace — a collection of non-standard methods that provide full externality trace functions on transactions executed on the Ethereum chain.
Debug — a collection of non-standard RPC methods to inspect and debug transactions.
Node API grants access to the largest number of blockchains on the market — 55+ chains with both Mainnets and Testnets available.
