I Built a Weather API That Tells You What to Do (Not Just the Forecast)

Every weather API returns raw numbers and leaves you to figure out what they mean. I wanted one that tells you what to do.

So I built ClimaIQ — 15 endpoints that turn weather into actionable decisions.

Instead of raw data, you get actionable insights:

Logistics: "Delay departure by 3 hours for safer conditions." (risk score: 67/100)

EV Trip: "Cold weather reduces range by 23%. Plan 2 charging stops."

Agriculture: "Apply 18.5mm of water now. High evapotranspiration detected."

Solar: "20.6 kWh expected today. Payback in 6.7 years. 51% ROI."

See it in action (JSON Response)

Since we are developers, here is what a typical response looks like:


json
{
  "recommendation": "Delay departure by 3 hours",
  "risk_score": 67,
  "reason": "High wind gusts and heavy rain on route",
  "impact_metrics": {
    "ev_range_reduction": "23%",
    "solar_yield_kwh": 20.6
  }
}

Features include:

Plain English summaries: Get readable labels like "Overcast, feeling cold at 10°".

Safety advice: UV index and Air Quality with specific health recommendations.

Road Safety: Route weather with hazard detection for travel.
Deep insights: Sunrise/sunset, feels-like labels, crop stress index, and EV range impact.

Tech Stack

Backend: Node.js / Express

Deployment: Vercel

Data Sources: Open-Meteo, OpenWeatherMap, and NWS

Optimization: Sub-second cached responses with automatic fallback.
