44 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.
Human-readable documentation for agents that need to understand a smart contract before calling it: function descriptions, parameter explanations, risk flags, and a security posture summary. Category: inference.
Exact unit conversion for crypto amounts: wei, gwei, ether, lamports, SOL, satoshis, BTC or a token with N decimals.
Solana rug check: is this token safe? Get a token risk score (0-100) and a SAFE / WARN / DANGER verdict for any Solana mint or pump.fun coin. Deterministic on-chain rubric: mint + freeze authority, Token-2022 traps, top-...
Payment flow verification for agents integrating x402: confirms your wallet and payment channel work before you spend on a real endpoint, and returns the full service catalog with prices and example inputs. Category: inf...
Decode EVM smart-contract transaction calldata into the function name and typed parameters. Supply an ABI (from /api/contract-abi) or a signature like transfer(address,uint256) for a fully offline decode; with neither, t...
Fetch the verified ABI for a contract address from an open verified-contract repository, plus a ready-to-use list of human-readable function signatures with their 4-byte selectors. Covers 8 EVM mainnets. Unverified contr...
Contract ABI Lookup: Ethereum mainnet ABI for any contract address. Ethereum mainnet contract ABI. Takes query parameter address (contract, 0x + 40 hex). Returns the contract's ABI as JSON when one is available for that...
Contract ABI, verified contract. The verified ABI of a smart contract on Ethereum, Base, Arbitrum, Optimism or Polygon from Sourcify's open verification repository: contract name, compiler, match quality, every function...
Fetch a verified smart-contract's full source, ABI, compiler settings and NatSpec docs for an EVM address, and automatically resolve a proxy to its implementation so the response also carries the implementation ABI. One...
EVM developer utilities: keccak256 hash, function selector from a signature, EIP-55 checksum address and wei/gwei/ether conversion.
Solidity abi.encodePacked equivalent — Genesis402 / UnyKorn Operator Network
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
Pad hex to a fixed byte width — Genesis402 / UnyKorn Operator Network
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...
Decode a Base transaction's calldata into a human-readable function call and arguments — ERC-20 transfer/approve and the EIP-3009 transferWithAuthorization used by x402 settlements. Recognizes x402 settlement transaction...
ABI and readable function/event signatures of a verified smart contract from Sourcify, with contract name, compiler, licence, proxy implementation and deployer. Use before calling or decoding a contract.
Decode calldata. Decode EVM transaction calldata into the function and its arguments with viem: give the function signature (transfer(address,uint256)), or leave it out to try common ERC-20, ERC-721, ERC-1155, WETH, perm...
Derive an Ethereum address from a public key — Genesis402 / UnyKorn Operator Network
EIP-191 digest of a message (what personal_sign actually signs) — Genesis402 / UnyKorn Operator Network
Event topic0 from a Solidity event signature — Genesis402 / UnyKorn Operator Network
EIP-712 typed-data digest — Genesis402 / UnyKorn Operator Network
Resolve ENS (.eth) on Ethereum and Basenames (.base.eth) on Base, forward or reverse. Returns address, name, source, forward_verified, optional avatar.
Use when an agent needs a contract value that none of the typed routes covers: it runs any read-only call with your own calldata on five chains and returns the raw 32-byte result plus asUint, so you can decode it yoursel...
