How this service works
[concierge json-pick] 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 JSON-pick formatted object containing current weather conditions (temperature, wind, sky conditions) and a structured up-to-7-day forecast from the National Weather Service, including daily high/low temperatures, precipitation probability, and weather descriptions for each period.
Example use cases

Technical details
Endpoint
POSThttps://x402-v2-mint-weather-forecast.vercel.app/v1/weather-forecast/fmt/json-pick?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative US government (NWS) weather data for US locations or territories with structured JSON output. Prefer it over the sibling Open-Meteo endpoint when official NWS data sourcing is important or required. Use the json-pick format when you want a pre-selected, concise JSON payload rather than CSV, Markdown, or custom formats. Not suitable for non-US locations — use the Open-Meteo sibling endpoint for international coverage.
Side effects
- Coordinates outside the US and its territories return a 400 error with code 'outside_us_coverage' and no charge is applied
- Invalid or missing latitude/longitude returns a 400 validation error
- NWS upstream API outages may cause 502/503 errors
- Coordinates in US waters far from land may lack NWS grid coverage and return an error
