As the server listed them on Oct 25, 2026. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • get_block_by_timestampGet Block By Timestampread-only

    Get the block number closest to a given Unix timestamp (seconds).

  • get_contract_abiGet Contract Abiread-only

    Get the verified ABI (JSON) for a contract address.

  • get_contract_creationGet Contract Creationread-only

    Get the creator address and creation transaction hash for up to 5 contract addresses. The multi-kilobyte creation bytecode is omitted by default to keep responses small; set include_creation_bytecode=true to include it.

  • get_contract_sourceGet Contract Sourceread-only

    Get the verified source code and metadata for a contract address.

  • get_gas_oracleGet Gas Oracleread-only

    Get current gas price recommendations (safe / propose / fast) from the gas tracker.

  • get_internal_transactionsGet Internal Transactionsread-only

    Get internal transactions for an address, or by a specific parent transaction hash.

  • get_logsGet Logsread-only

    Search event logs by contract address and/or topics over a block range. Topics are 32-byte hex values; topic0 is usually the keccak256 event-signature hash. Adjacent-topic operators (and/or) combine multiple topic filters. Provide 'address' and/or at least one topic.

  • get_native_balanceGet Native Balanceread-only

    Get the native coin (e.g. ETH) balance of an address, in wei.

  • get_supported_chainsGet Supported Chainsread-only

    Get the chains / chain IDs supported by the Etherscan V2 API. In the hosted (proxy) deployment this returns a bundled snapshot shipped with the server, refreshed when the package is updated; in direct/stdio mode it queries the live chain-list endpoint. A chain's absence from the returned list is not proof that it lacks live support.

  • get_token_transfersGet Token Transfersread-only

    Get token transfer events for an address, optionally filtered by token contract. Select the token standard: erc20 (fungible, default), erc721 (NFT), or erc1155 (multi-token).

  • get_transaction_by_hashGet Transaction By Hashread-only

    Get the full transaction object for a transaction hash (from, to, value, input data, gas, gas price, nonce, block number/hash, transaction index). Returns null if the hash is unknown.

  • get_transaction_receiptGet Transaction Receiptread-only

    Get the transaction receipt for a transaction hash (execution status, gas used, cumulative gas used, effective gas price, logs, and the created contract address for deployments). Returns null if the hash is unknown or the transaction is still pending.

  • get_transaction_receipt_statusGet Transaction Receipt Statusread-only

    Get the receipt status of a transaction (1 = success, 0 = failed). Post-Byzantium only.

  • get_transaction_statusGet Transaction Statusread-only

    Get the contract execution status of a transaction (detects failed/erroring executions).

  • get_transactionsGet Transactionsread-only

    Get the list of normal (external) transactions for an address.

  • render_etherscan_widgetShow Etherscan Resultread-only

    Present exact facts returned by Etherscan data tools in a fast explorer-style card. Call the relevant Etherscan data tool first and copy only supported values into this tool. Never invent scores, risk labels, historical prices, forecasts, or audit conclusions.

  • resolve_ens_nameResolve Ens Nameread-only

    Resolve an ENS name (or onchain subdomain, e.g. etherscan.eth or gm.etherscan.eth) to its Ethereum address. Ethereum mainnet only. Offchain names that require CCIP Read / wildcard resolution (e.g. *.base.eth) are not supported.
