Storage slot read, Unichain. Read one raw storage slot of a contract on Unichain (eth_getStorageAt): the 32-byte word, as a number and, when it holds one, as an address. Slot is a decimal index or a 0x 32-byte key (mappi...
Eth call, zkSync contract call. Read-only contract call on zkSync Era (eth_call): send ABI-encoded calldata to a contract at the latest block and get the raw return data, without a transaction or gas. Use to read any vie...
zkSync Era contract check. Check whether a 0x address on zkSync Era is a smart contract or a plain wallet: bytecode size, and whether it is an EIP-1167 minimal proxy and which implementation it points to. Use before send...
Proxy implementation, zkSync. Find the implementation behind a proxy contract on zkSync Era: reads the EIP-1967 implementation, beacon and admin slots, EIP-1822 (UUPS), the older OpenZeppelin layout and EIP-1167 minimal-...
Storage slot read, zkSync. Read one raw storage slot of a contract on zkSync Era (eth_getStorageAt): the 32-byte word, as a number and, when it holds one, as an address. Slot is a decimal index or a 0x 32-byte key (mappi...
Token Quick Check: Base contract facts -- name, supply, owner, code. Not financial advice. Returns: a token verdict preview on one token contract: the contract facts the full verdict reads -- code size, name, symbol, dec...
Is this Ethereum address a contract or a wallet? EOA, EIP-7702 delegated wallet or smart contract, bytecode size, ETH balance and ERC-20 symbol. Safety check before sending funds.
Is this address a contract or a wallet? Checks any Base address: EOA, EIP-7702 delegated wallet or smart contract, bytecode size, ETH balance and ERC-20 symbol. Cheap safety check before sending funds.
X402 Asset Match: compares a challenge asset identifier with buyer-supported assets using only bounded caller-supplied values. Call when you need a bounded x402 asset match result before paying for or accepting an x402 o...
Agent Result Citation Check: checks bounded citation objects for URL and title fields using only bounded caller-supplied values. Call when you need a bounded agent result citation check result before paying for or accept...
Agent Result Error Shape Check: checks an agent error object for code, message, and retryability using only bounded caller-supplied values. Call when you need a bounded agent result error shape check result before paying...
X402 Delivery Content Type Check: compares delivery content type with buyer-accepted media types using only bounded caller-supplied values. Call when you need a bounded x402 delivery content type check result before payi...
X402 Settlement Network Check: compares settlement chain with the accepted challenge network using only bounded caller-supplied values. Call when you need a bounded x402 settlement network check result before paying for...
Determine whether an address on Base is a contract or an externally owned account. POST {"address":"0x..."} and receive isContract, the bytecode size in bytes and its keccak-256 hash. Useful before sending funds to an un...
Contract or EOA by address: code size, token name/symbol/decimals/supply, EIP-7702 delegation, read-only.
Contract or EOA by address: code size, token name/symbol/decimals/supply, EIP-7702 delegation, read-only.
Live Korea kimchi premium: Upbit KRW vs global USD for BTC and ETH, plus USD/KRW FX. Korea crypto arb/sentiment signal. Optional symbols=BTC,ETH filter. Alias: /kr/kimchi-premium.
JSON Schema validation without external libraries: validates data against a schema supporting type, required, properties, additionalProperties, items, enum, const, min/max (length, items, properties, numeric, exclusive),...
Fetch the verified ABI for a contract address from Sourcify, plus a ready-to-use list of human-readable function signatures with their 4-byte selectors. Covers 8 EVM mainnets. Unverified contracts return a structured {ve...
Decentralised exchange volumes: totals, 24h/7d/30d windows, per-chain and per-protocol breakdowns, all in one payload cached at the edge. For market-structure work and volume share screens.
Is this address a contract? On Ethereum, Base, Arc or BNB Chain: whether code is deployed, its size, the implementation behind an EIP-1967 or ZeppelinOS proxy, and an EIP-7702 delegation if the address is a wallet that d...
Contract-code check for a Base mainnet address (is_contract + code size + EIP-7702 delegated-EOA detection).
Raw storage slot (eth_getStorageAt) of a Base contract. Use when an agent needs proxy implementation/admin slots or raw contract state.
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...
