Airport delays, US ground stops. Live FAA National Airspace System status for US airports: ground stops, ground delay programs, arrival and departure delays (with minimum, maximum and trend) and closures, each with its reason. Give an IATA code such as LGA for one airport (normal when nothing is reported), or nothing for the whole country. Public FAA data, refreshed about every minute. Use before travel planning, logistics or customer notices.

Token allowance, Arbitrum ERC-20. ERC-20 token allowance on Arbitrum One: how much a spender may move from an owner's wallet (allowance), raw and in token units, and whether the approval is unlimited. Use to check an approval before a swap or to audit risky open approvals; for the owner's balance use arb_token_balance. Token is a ticker (USDC, USDT, WETH…) or a 0x contract; a missing contract is 404 and a non-ERC-20 422, both uncharged.

Eth call, Arbitrum contract call. Read-only contract call on Arbitrum One (eth_call) at the latest block, without a transaction or gas: send ABI-encoded calldata, or a function signature such as balanceOf(address) with args and the call is encoded and its result decoded for you. Use to read any view function that has no dedicated tool (the example reads USDC totalSupply). Calldata up to 8 KB; a call that reverts is 422 with the reason, uncharged.

Estimate gas, Arbitrum. Estimate the gas a transaction would use on Arbitrum One (eth_estimateGas) and what it would cost at the current gas price, in gas units, gwei and ETH. Give to, plus value in ETH and calldata for a contract call, and the sender when the call depends on it. Use before sending a transaction or to price a batch; for the gas price alone use arb_gas. A transaction that would revert is 422 with the reason, uncharged.

Use to judge whether fees are rising, pick a priority fee or time a transaction; for the current price alone use arb_gas.
