Free Weather API: Get Weather Data by Coordinates (JSON, REST)

If you are building an application that needs weather data, climate history, terrain analysis, or environmental information, the PixelGust API gives you access to all of this through a simple REST interface. Send coordinates, get JSON back. No complex setup or expensive subscriptions required.

What Data Is Available?

      "temperature_c": {"mean": 5.2, "min": 2.1, "max": 8.3},
      "precipitation_mm": {"sum": 48.2},
      "solar_radiation_mj": {"mean": 6.1}
    },
    ...
  }
}

Terrain and Environment

Terrain, NDVI, land cover, and demographics are included in the standard response:

Response includes:
{
  "elevation_m": 52,
  "slope_deg": 3.2,
  "aspect": "SE",
  "twi": 8.4,

}

Use Cases

Real Estate Platforms

Enrich property listings with environmental data. Show buyers the climate profile, flood risk, and terrain characteristics of every property. Call the API with the property coordinates to get instant environmental context.

Agricultural Tech

Build precision agriculture tools that use NDVI, weather history, and soil data to provide actionable insights for farmers. The historical weather endpoint gives you the climate baseline needed for crop suitability analysis.

Renewable Energy Software

Integrate solar radiation and wind speed data into energy yield estimation tools. The 10-year historical dataset provides the statistical foundation for bankable resource assessments.

Insurance and Risk Platforms

Automate climate risk scoring for property portfolios. Combine hazard data (flood, erosion), weather extremes, and terrain characteristics to generate risk profiles at scale.

IoT and Smart Home

Add hyper-local weather context to IoT dashboards. Current weather data helps smart home systems optimize heating, cooling, and irrigation based on actual conditions.

Rate Limits and Pricing

The free tier provides a generous number of API requests per month. For higher volumes, enterprise plans are available. Visit the API Keys page in the dashboard for current limits and upgrade options.

Response Format

All responses are in JSON format with consistent key naming. Timestamps use ISO 8601. Temperatures are in Celsius, distances in meters/kilometers, and all units are documented in the response metadata. Error responses include descriptive messages with HTTP status codes.
