380 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.
EVM Amount Min Check: checks an actual raw amount against a minimum raw amount using only bounded caller-supplied values. Call when you need a bounded evm amount min check result before signing, submitting, replacing, or...

EVM Priority Fee Ratio: calculates the priority-fee share of the total fee cap using only bounded caller-supplied values. Call when you need a bounded evm priority fee ratio result before signing, submitting, replacing,...
EVM Signature V Classify: classifies common signature recovery and EIP-155 v values using only bounded caller-supplied values. Call when you need a bounded evm signature v classify result before signing, submitting, repl...
EVM Slippage Bounds Check: checks expected and minimum output against a maximum slippage policy using only bounded caller-supplied values. Call when you need a bounded evm slippage bounds check result before signing, sub...
EVM Token Balance Budget: checks caller-supplied raw token balance against transfer amount using only bounded caller-supplied values. Call when you need a bounded evm token balance budget result before signing, submittin...
EVM Transfer Recipient Check: compares an encoded recipient address with the intended recipient using only bounded caller-supplied values. Call when you need a bounded evm transfer recipient check result before signing,...
JSON-RPC read access to EVM chains (base, ethereum, polygon, arbitrum, optimism) with no API key. Send a standard JSON-RPC body (eth_call, eth_getBalance, eth_blockNumber, eth_getLogs). Also callable as GET with the same...
One validator: its status, balance and activation window. PulseChain (chain id 369). $0.003 USDC per call.
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.
Check an unsigned EVM transaction before an AI agent signs it. Enforces spending limits, recipient restrictions, ERC20 approval rules, unlimited approval protection, and calldata policy. Only PASS receives a short-lived...
EVM Watchdog: npm/Foundry dependency advisories split by on-chain vs toolchain surface, plus known Solidity bug-class leads, for a public GitHub repo. A scan, not an audit.
Use this before approving or depositing into a contract on Base or Robinhood Chain: is it a proxy, who can change its code (single key, Safe with threshold, timelock with delay), who owns it, is the live code verified on...
Use this to be told when a contract you rely on (Base, Robinhood Chain) gets new code, a new owner or weaker upgrade rules, or when a new advisory hits your npm lockfile: 30 days of hourly checks, signed webhook on each...
Decodes the real recipient or spender from EVM calldata - transfer, transferFrom, approve, increaseAllowance, permit, setApprovalForAll, Uniswap V2 swaps and Multicall3 - and checks it against your allowlist and epoch ca...

Combined pre-trade safety check: on-chain risk score (proxy + privileged-function detection from live bytecode) plus Telegram alert-channel monitoring, in one call. Cheaper than calling /v1/scan and /v1/alert-check separ...
ERC-20 metadata on Base: name, symbol, decimals, totalSupply for any token contract.
Transaction count (nonce) for a Base address, latest and pending.
ERC-20 allowance(owner, spender) on Base, raw + formatted, flags unlimited approvals.
Base block summary by number or latest: hash, timestamp, tx count, gas used/limit, base fee.
