How this service works
NWS point metadata for a US lat/lon: forecast office, grid x/y, time zone, county, nearest observation station and the NWS forecast links. Changes rarely. From the NWS (US and territories), cached and refreshed about every 3 hours; a location not yet cached answers 404, is not charged, and is queued.
Output
A JSON object containing: latitude, longitude, SKU identifier, NWS Weather Forecast Office (WFO) code, grid X and Y coordinates, state name, county zone URL, country, IANA timezone string, forecast URL (linking to the NWS gridpoint forecast), and forecast office URL.
Example use cases
Resolve location to NWS forecast URL
“I need the NWS forecast URL for the coordinates 39.7392 latitude and -104.9903 longitude so I can pull the actual weather forecast for Denver.”
Find weather office for a field site
“Our field team is working at 41.8781° N, 87.6298° W in Chicago — can you tell me which NWS forecast office covers that point and what the grid coordinates are?”
Enrich location data with timezone and county
“Given coordinates 47.6062 latitude and -122.3321 longitude for Seattle, what timezone and NWS county zone does that location fall under?”
Technical details
Endpoint
GEThttps://api.maxwellinternational.ai/v1/weather/point?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve a US latitude/longitude coordinate to NWS grid metadata — particularly when you need the WFO code, grid X/Y, forecast URL, timezone, or county zone for a point. It is a lightweight, low-cost lookup step before fetching actual NWS forecast data. Prefer this over calling the NWS API directly when payment is handled via x402 micropayments and you want a clean JSON wrapper around the NWS point resolution response.
Side effects
- Coordinates outside the US (NWS only covers US territories) — likely returns an error or empty result
- Invalid or missing lat/lon query parameters — bad request error
- NWS upstream API unavailability causing downstream failure
- Coordinates in ocean or unsupported region returning no grid match
