US Weather Forecasts & Alerts (National Weather Service)

7-day or hourly forecasts for any US lat/lon (temperature, precip probability, humidity, wind, text forecast) and active weather alerts by state or severity, from the free NWS API.

Why this actor

• Commercial-use-safe public-domain data (unlike some free weather APIs).
• Pay only for results: $0.50 per 1,000 rows, no start fee, failed lookups are free.
• Robust: automatic retries with exponential backoff, respects Retry-After, per-item error rows instead of crashed runs.
• Clean, flat JSON/CSV/Excel output ready for Google Sheets, Make, Zapier, n8n, Clay, or the Apify API.

Use cases

• Field-service and logistics planning
• Event and construction scheduling
• Alert-driven marketing (e.g. HVAC, roofing)
• Prediction-market research
