Is x402-seller-data-api live?

Yes — it answered the hub's last check (checked 7m ago). It answered 99% of checks over the last 30 days.

Is x402-seller-data-api free to use?

Not measured yet.

What tools does x402-seller-data-api have?

22 tools: earthquakes_recent, treasury_debt, ocean_tides, geo_reverse, geo_lookup, oil_price, electricity_price, weather_forecast, ….

Is x402-seller-data-api safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• earthquakes_recent reads unknown never probed

  Check for recent significant earthquakes, quakes, or seismic activity anywhere in the world, from the past 7 days, sourced from USGS (US Geological Survey). Answers questions like "was there an earthquake near me", "how strong was the recent quake in X", or "list major earthquakes this week". Optional 'minmagnitude' filters by minimum magnitude (default 4.5), and 'limit' caps the number of results (default 10, max 50). Costs $0.001 per call, paid via x402 (USDC on Base).

• treasury_debt reads unknown never probed

  Current total U.S. national debt outstanding — how much the U.S. government owes right now — from the Treasury's 'Debt to the Penny' data: total public debt outstanding, debt held by the public, and intragovernmental holdings.

• ocean_tides reads unknown never probed

  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. Costs $0.001 per call, paid via x402 (USDC on Base).

• census_demographics reads unknown never probed

  US Census Bureau American Community Survey (ACS) 5-Year estimates for a ZIP code: total population, median household income, median age, and total housing units. ZIP codes map to Census ZCTAs (Census-drawn approximations); some ZIPs (PO-box-only or very new) have no ZCTA match and return 404. Reflects a rolling 5-year survey window, not real-time. Costs $0.001 per call, paid via x402 (USDC on Base).

• water_streamflow reads unknown never probed

  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). Costs $0.001 per call, paid via x402 (USDC on Base).

• water_flood_risk reads unknown never probed

  Flood risk at a US river gauge: current water level measured against the official National Weather Service flood stages (action, minor, moderate, major), how many feet remain before each one is reached, and NOAA's own observed and forecast flood category. Answers "is this river near flooding". Takes a USGS site number or an NWS gauge ID. Not every gauge has official flood stages. Costs $0.001 per call, paid via x402 (USDC on Base).
