Query native token balances, ERC-20 token balances, transaction history, verified contract ABIs, and current gas prices across six supported networks. ## Supported Chains | Chain Value | Network | |---|---| | `ethereum` | Ethereum Mainnet (default) | | `base` | Base L2 | | `base_sepolia` | Base Sepolia Testnet | | `polygon` | Polygon PoS | | `arbitrum` | Arbitrum One | | `optimism` | Optimism Mainnet | ## Actions ### balance Get the native token balance (ETH or MATIC) for one or more wallet addresses. **Required fields:** - `action`: `"balance"` - `address`: Array of 1-20 wallet addresses (0x-prefixed, 42-character hex strings) **Optional fields:** - `chain`: Network to query (default: `"ethereum"`) **Example - Single address on Ethereum:** ```json { "action": "balance", "address": ["0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"] } ``` **Example - Multiple addresses on Polygon:** ```json { "action": "balance", "chain": "polygon", "address": [ "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045", "0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B" ] } ``` **Response includes:** Each address with its balance in native units and in wei, the chain name, and the native token symbol (ETH or MATIC for Polygon). --- ### token_balance Get ERC-20 token balances for one or more wallet addresses. Supports major stablecoins and wrapped tokens. **Required fields:** - `action`: `"token_balance"` - `address`: Array of 1-20 wallet addresses **Optional fields:** - `chain`: Network to query (default: `"ethereum"`) - `token`: Token symbol to query (e.g., `"USDC"`, `"USDT"`, `"DAI"`, `"WETH"`, `"PYUSD"`). Use `"all"` to query all supported tokens on the chain. Defaults to `"all"` if omitted. **Supported tokens by chain:** - **Ethereum:** USDC, USDT, PYUSD, DAI, WETH, WBTC - **Base:** USDC, USDbC, DAI, WETH - **Polygon:** USDC, USDC.e, USDT, DAI, WETH, WMATIC - **Arbitrum:** USDC, USDC.e, USDT, DAI, WETH - **Optimism:** USDC, USDC.e, USDT, DAI, WETH **Example - Get USDC balance on Ethereum:** ```json { "action": "token_balance", "address": ["0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"], "token": "USDC" } ``` **Example - Get all token balances on Base:** ```json { "action": "token_balance", "chain": "base", "address": ["0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"], "token": "all" } ``` **Response includes:** Each address with token balances (formatted balance, raw balance, decimals) for the requested tokens. --- ### transactions Get transaction history for a single address. Returns transactions sorted by most recent first, in pages of exactly 100. **Required fields:** - `action`: `"transactions"` - `address`: Array with exactly 1 wallet address **Optional fields:** - `chain`: Network to query (default: `"ethereum"`) - `transaction_range`: Array of two integers `[start, end]` defining which 100-transaction window to fetch. Index 1 is the most recent transaction. Must span exactly 100 items. Default: `[1, 100]`. **Example - Most recent 100 transactions:** ```json { "action": "transactions", "address": ["0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"] } ``` **Example - Transactions 101-200 on Arbitrum:** ```json { "action": "transactions", "chain": "arbitrum", "address": ["0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"], "transaction_range": [101, 200] } ``` **Response includes:** Each transaction with hash, block number, timestamp, from/to addresses, value in ETH and wei, gas details, input data, and error status. --- ### contract_abi Retrieve the ABI (Application Binary Interface) for a verified smart contract. **Required fields:** - `action`: `"contract_abi"` - `address`: Array with exactly 1 contract address **Optional fields:** - `chain`: Network to query (default: `"ethereum"`) **Example - Get ABI for a contract on Ethereum:** ```json { "action": "contract_abi", "address": ["0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48"] } ``` **Example - Get ABI on Optimism:** ```json { "action": "contract_abi", "chain": "optimism", "address": ["0x0b2C639c533813f4Aa9D7837CAf62653d097Ff85"] } ``` **Response includes:** The full ABI array, plus counts of functions and events in the contract. --- ### gas_oracle Get current gas price estimates for a blockchain network. Returns safe (slow), standard, and fast gas prices. **Required fields:** - `action`: `"gas_oracle"` **Optional fields:** - `chain`: Network to query (default: `"ethereum"`) **Example - Ethereum gas prices:** ```json { "action": "gas_oracle" } ``` **Example - Polygon gas prices:** ```json { "action": "gas_oracle", "chain": "polygon" } ``` **Response includes:** Safe, standard, and fast gas price estimates (in Gwei), suggested base fee, gas used ratio, and timestamp. --- ## Common Workflows ### Check a wallet's full portfolio 1. Call `balance` to get native ETH/MATIC balance 2. Call `token_balance` with `token: "all"` to get all ERC-20 holdings ### Investigate transaction activity 1. Call `transactions` with default range `[1, 100]` for the latest 100 transactions 2. Page through older transactions with `[101, 200]`, `[201, 300]`, etc. ### Inspect a smart contract 1. Call `contract_abi` to retrieve the verified ABI 2. Use the ABI to understand available functions and events ### Estimate transaction costs 1. Call `gas_oracle` to get current gas prices on the target chain ## Important Notes - All addresses must be 0x-prefixed, 42-character hexadecimal strings. - The `balance` and `token_balance` actions accept up to 20 addresses per request. - The `transactions` and `contract_abi` actions require exactly 1 address. - The `gas_oracle` action does not require any address. - The `transaction_range` must always span exactly 100 transactions (e.g., `[1, 100]`, `[101, 200]`). - On Polygon, the native token is MATIC; on all other chains it is ETH. - The `contract_abi` action only works for verified contracts. Unverified contracts will return an error. - Token availability varies by chain. If a token is not supported on the selected chain, the tool returns an error listing available tokens. - Base Sepolia (testnet) has no preconfigured ERC-20 tokens for `token_balance`. ### About The Developer - Vendor name: Apoth3osis - Website: apoth3osis.io We build tools that enable AI agents to excel in the mathematical realm.
