381 services carry this tag in their source record. Tags come from the provider, not from us — a tag is a claim about what the service does, not proof that it does it well.

Block number, Polygon PoS. Latest block number and block details on Polygon PoS, or any block by decimal number: hash, timestamp, transaction count, gas used and limit, base fee in gwei and producer. Use for timestamps a...
Encode a contract function call (calldata) from its signature and arguments, e.g. transfer(address,uint256) with [to, amount]: selector and hex data ready to sign or simulate.
Recover which address signed a message — Genesis402 / UnyKorn Operator Network
Inspect any BNB Smart Chain address: EOA vs contract vs EIP-7702 delegated, BNB balance, nonce, proxy implementation (EIP-1967/1167/zos), and ERC-20 name/symbol/decimals/supply.
Current gas prices for Base or Ethereum mainnet: legacy gas price, EIP-1559 base fee and suggested priority fee (all gwei), plus the latest block number. Query: chain (base | ethereum, default base). Real-time from publi...
EVM gas oracle for any major chain - Ethereum, Base, Arbitrum, Optimism, Polygon, BNB, Avalanche: next-block baseFee plus slow, med and fast priority-fee tiers (maxFeePerGas and maxPriorityFeePerGas), read live from chai...
Reference data for a blockchain by its chainId: name, gas/native token, block explorers, number of public RPCs and website. Utility for multi-chain agents. Live from chainid.network (ethereum-lists, open data).
Decode EVM calldata (transaction input) with the function signature you provide, checking that it matches the selector, or decode return data with its output types (e.g. uint256,address). Local calculation, no third-part...
Keyless public RPC endpoints (HTTPS and WebSocket) of any EVM chain by name or chainId, with block explorers, native currency and website. Lets an agent connect to any chain.
Inspect any Ethereum address: EOA vs contract vs EIP-7702 delegated, ETH balance, nonce, proxy implementation (EIP-1967/1167/zos), and ERC-20 name/symbol/decimals/supply.
Current EIP-1559 gas fees for Ethereum, Base, Arbitrum, Optimism or Polygon: next base fee, slow/standard/fast priority and max fee in gwei, block utilisation and the cost of a plain transfer (L2 L1-data fees excluded)....
Tokens seen most recently. PulseChain (chain id 369). $0.003 USDC per call.
Check a Ethereum wallet's ERC-20 approvals: allowances for 8 major tokens (USDC, USDT, WETH, DAI...) to common spenders (Permit2, Uniswap Universal Router v4, Uniswap Universal Router, Uniswap SwapRouter02...); flags unl...
Decode an EVM signature request (EIP-712 typed data, Permit/Permit2, or ERC-20 approve calldata) into a structured intent: what token, which spender, how much, until when, plus risk_flags and an action_hint. Deterministi...
Fetch a block header by number, hash, or "latest" on Ethereum, Base, Arbitrum, Optimism, Polygon, or BNB Chain: timestamp, miner, gas used/limit, base fee, transaction count, size. Public JSON-RPC, no API keys. POST a JS...
Everything cheap that is knowable about an address, in one call — Genesis402 / UnyKorn Operator Network
Solidity abi.encodePacked equivalent — Genesis402 / UnyKorn Operator Network
Arbitrum One native balance. Native ETH balance (eth_getBalance) of any 0x wallet address on Arbitrum One at the latest block, in wei and in ETH. Use to check whether a wallet can pay gas or a transfer; for ERC-20 tokens...
Arbitrum One gas price. Current gas price on Arbitrum One (eth_gasPrice): gas price, base fee and suggested priority fee in gwei, plus what a plain ETH transfer (21,000 gas) costs right now. Takes no input. Use before se...
Arbitrum One recent event logs. Recent contract event logs on Arbitrum One (eth_getLogs): the events a contract emitted over the last N blocks (1-1,000, default 50), optionally filtered by topic0 (the 0x 32-byte event si...
Arbitrum One account nonce. Read the transaction count (nonce) of a 0x address on Arbitrum One, both confirmed and including pending transactions. Use to build the next transaction or to tell whether an address has ever...
Arbitrum One transaction. Look up an Arbitrum One transaction by hash: sender, recipient, value in ETH, nonce, gas limit, the 4-byte function selector and its block. Use to see what was sent or whether it exists; for suc...
Base recent event logs. Recent contract event logs on Base (eth_getLogs): the events a contract emitted over the last N blocks (1-1,000, default 50), optionally filtered by topic0 (the 0x 32-byte event signature hash). R...
