How this service works
Hour-by-hour forecast for any US coordinate: temperature, precipitation chance, wind, conditions for the next 48 hours. Source: National Weather Service. JSON.
Output
A JSON array of hourly forecast objects for the next 48 hours, each containing a timestamp, temperature (in °F), short forecast description (e.g. 'Partly Cloudy'), and precipitation chance percentage. Also includes a resolved location name string for the queried coordinate.
Example use cases
Outdoor event day planning
“I'm hosting an outdoor wedding reception in Austin, TX this Saturday. Can you pull the hourly weather forecast for the next 48 hours so I know exactly when to expect rain or strong winds?”
Construction crew scheduling
“We have a crew working a job site near Denver, CO — can you get the hour-by-hour forecast for the next two days so we can schedule the outdoor concrete pour when precipitation chance is lowest?”
Hiking trip conditions check
“My hiking group is heading to Asheville, NC tomorrow. Show me the hourly temperatures, precipitation chances, and conditions so we can pick the best window to be on the trail.”
Technical details
Endpoint
GEThttps://api.polyform.org/v1/weather/hourly?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need granular, hour-by-hour weather resolution for US locations over the next 48 hours — ideal for event planning, logistics, outdoor scheduling, or any use case requiring intraday weather timing. Prefer this over a daily or 7-day forecast endpoint when the hour-of-day matters. Since it sources directly from the National Weather Service, it is authoritative for US locations. Use the sibling current-conditions endpoint if you need observed (real-time) data rather than a forecast.
Side effects
- Coordinates outside the continental US or US territories will fail — NWS only covers US locations
- Missing or malformed lat/lon query parameters will return a 400 error
- NWS upstream outages may cause 502 or 503 responses
- Payment not included or insufficient USDC balance results in 402 Payment Required response
- Very remote US coordinates may not map to a NWS grid point, returning a location resolution error
