How this service works
[concierge custom] US weather: current + up to 7-day forecast from the National Weather Service (api.weather.gov). US and territories only; non-US lat/lon → 400 outside_us_coverage, not charged. Data only — not advice.
Output
A structured custom-format response containing current weather conditions (temperature, wind, sky/precipitation state) and up to 7 daily forecast periods sourced from the National Weather Service, covering the requested US or territory location. Non-US coordinates return a 400 error and are not charged.
Example use cases
Outdoor event weather planning
“Can you pull the current conditions and 7-day NWS forecast for Denver, Colorado — coordinates 39.74 lat, -104.98 lon — I'm planning an outdoor concert there next weekend and need to know what the weather will be like.”
Daily weather briefing for US field crew
“Grab me the current weather and up to 7-day forecast from the National Weather Service for Houston, Texas — lat 29.76, lon -95.37 — in the custom format so I can brief the field crew each morning.”
Travel preparation for US trip
“I'm flying to Honolulu, Hawaii next week — can you get me the current conditions and a 7-day forecast from the National Weather Service using lat 21.31, lon -157.86 so I know what to expect?”

Endpoint
POSThttps://x402-v2-mint-weather-forecast.vercel.app/v1/weather-forecast/fmt/custom?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative National Weather Service forecast data for US locations (including territories) with up to 7 days of forecast detail, and you want a custom concierge output format. Prefer it over the Open-Meteo sibling endpoint when NWS sourcing is required or the user is explicitly in the US. Use the JSON, CSV, or Markdown sibling variants if a different output format is needed. Not suitable for non-US locations.
Side effects
- Coordinates outside US coverage (non-US lat/lon) → 400 outside_us_coverage error, no charge
- NWS api.weather.gov upstream outage or timeout → service unavailable error
- Malformed or missing lat/lon inputs → 400 bad request
- Coordinates in US waters with no NWS grid coverage → lookup failure
