How this service works
48 live public-data tools (security, packages, SEC filings, economy, FX, weather, domains, Federal Register, Base) for AI agents. $0.002 USDC per call on Base via x402, charged only on success. The same tools are free for 100 calls/day via MCP at <server>.datakoot.com/mcp.
Output
A JSON object containing the forecast type (daily or hourly), data source attribution (NWS/NOAA), location name, timezone, and an array of forecast periods. Each period includes a name (e.g. 'Saturday', 'Overnight'), start time, daytime flag, temperature, wind speed and direction, short summary, detailed narrative description, and precipitation probability.
Example use cases
Outdoor event planning weather check
“I'm planning an outdoor event in Denver this weekend — can you pull the daily weather forecast for latitude 39.7392, longitude -104.9903 so I know what conditions to expect?”
Hourly forecast for a field operation
“I need the hourly weather forecast for lat 41.8781, lon -87.6298 for today — give me temperature and wind hour by hour so we can schedule the crew properly.”
Precipitation probability lookup for logistics
“What are the precipitation chances and wind conditions for the next few days at latitude 29.7604, longitude -95.3698? We need to decide whether to delay the outdoor shipment.”
Technical details
Endpoint
POSThttps://x402.datakoot.com/api/weather_forecast?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative US weather forecasts from NOAA/NWS at a specific lat/lon coordinate, either daily periods or hourly breakdowns, with precipitation probability and wind data. Prefer it over commercial weather APIs when you want public-domain government data, pay-per-use micropayment pricing ($0.002 USDC), and no subscription required. Not suitable for non-US locations.
Side effects
- Coordinates outside the US (NWS only covers US territory) — returns an error or empty response
- Invalid or missing lat/lon values — schema validation error
- NWS API upstream outage — returns a service unavailable error
- Payment failure via x402 — call is not charged and not executed
- Coordinates in a US territory not covered by NWS grid — may return a not-found error
