282 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 Finality Depth Check: checks confirmation count against a caller-required depth using only bounded caller-supplied values. Call when you need a bounded evm finality depth check result before signing, submitting, repl...
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.
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...
Detect language, formality and tone of a text with confidence scores. Deterministic heuristics + compact wordlists. Returns iso_639-1 + register. — $0.001 USDC/call on eip155:8453. Pay-per-call via x402 — no API key, no...
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.
Current Base mainnet block number. Lightest endpoint — single eth_call.
Current Base mainnet gas price (wei/gwei), EIP-1559 base/priority fees, gas_price_usd. One-call light.
ETH balance of a Base mainnet address, incl. balance_usd.
ERC-20 token balance of a Base mainnet address, incl. symbol, decimals, balance_formatted.
Transaction details by hash on Base mainnet.
