Real-time river and stream conditions at a USGS stream gauge — current streamflow/discharge (cubic feet per second) and gauge height/water level/stage (feet), i.e. how much water is flowing and how high it is right now. Data is provisional and subject to revision. Requires a USGS site number (e.g. 09380000 = Colorado River at Lees Ferry, AZ).

Forward geocode a free-text address, place name, or city (e.g. "Tokyo, Japan") into geographic coordinates — latitude and longitude — plus its IANA timezone. Use this to convert a location description into coordinates for mapping, distance, or timezone-aware lookups, or as the first step before coordinate-based endpoints like weather forecasts.

Current crude oil price in USD per barrel — WTI or Brent spot price from the U.S. Energy Information Administration (EIA). Reflects the latest official daily figure, not live or real-time trading data; lags the market by several business days.

Latest Henry Hub natural gas spot price (USD/MMBtu), sourced from the U.S. Energy Information Administration. Data lags several business days behind the market; not live trading data.

Check a wallet's live balance on Base mainnet: native ETH (e.g. to confirm it has enough for gas) plus an optional ERC20 token balance (e.g. USDC) when a token contract address is supplied. Sourced from Base's official public RPC.

U.S. coastal tide data from NOAA — when's the next high or low tide, or what's the water level right now: high/low tide predictions for the next 48 hours (product=predictions, default), or the latest observed water level (product=water_level). Identify the location by NOAA CO-OPS station ID, or just pass lat+lng and the nearest station is used automatically (distanceKm in the response says how far it is). Heights in feet above MLLW datum, times in GMT.
