Why people use Ankr (Web3 Node API)

Ankr (Web3 Node API) for Real-Time Blockchain Data

With this Connector, that friction disappears. Your AI agent becomes your dedicated blockchain terminal. You can stay in your workspace and simply ask for the data you need. Instead of hunting for a receipt, your agent pulls it instantly, giving you a clear picture of the on-chain state without the tab-switching headache.

What Vinkius changes

You get a direct conversational bridge to EVM blockchain data without managing your own node infrastructure.

Use it from Claude, ChatGPT, Cursor or another AI client you already have.

Before you connect

Questions about Ankr.

The practical details behind the request, access and result.

Can Ankr (Web3 Node API) help me check my wallet balance?

Yes, it allows your AI agent to instantly pull the balance of any wallet on Ethereum and other EVM chains. You can ask for the balance of a specific address in plain English and get the result immediately.

How does Ankr (Web3 Node API) work with my AI agent?

It acts as a bridge. Once connected, your AI agent can use the capabilities provided by this Connector to fetch real-time blockchain data, query smart contracts, and simulate transactions on your behalf.

Can I use Ankr (Web3 Node API) to see NFT ownership?

Yes, you can ask your agent to list all NFTs owned by a specific address or to find all holders of a specific collection. It pulls this data directly from the blockchain for you.

Does Ankr (Web3 Node API) support multiple EVM chains?

It supports Ethereum and other EVM-compatible chains. This means you can query data across a wide range of networks using the same connection.

Can Ankr (Web3 Node API) estimate gas for me?

Yes, it can. Your agent can use the estimation capability to tell you exactly how much gas a transaction will cost before you send it, helping you avoid stuck transactions.

How do I use Ankr (Web3 Node API) to debug a smart contract?

You can ask your agent to execute calls to read contract states or to simulate complex transactions. This lets you see how a contract will behave without spending any gas.

Is Ankr (Web3 Node API) good for DeFi research?

It's excellent for research. It allows you to quickly pull historical transfer data, token prices, and whale interactions, making it much faster to gather on-chain data for analysis.

How can I check the current block height on a specific network?

Use the eth_blockNumber capability and provide the chain_alias (e.g., 'eth' for Ethereum). The agent will return the most recent block number recorded on that chain.

Is it possible to simulate a transaction before sending it to the mainnet?

Yes! You can use the eth_simulateV1 capability. By providing a simulation payload, you can see the potential outcome and state changes of transactions without actually broadcasting them.

How do I retrieve the balance of a specific wallet address?

Simply use the eth_getBalance capability with the target address and chain_alias. The agent will fetch the current balance in Wei for that account.
