Orthogonal Weather Forecast

How It Works

Uses the Precip API to get weather data from meteorological sources.

Usage

Get Daily Forecast

curl -s -X POST $GOOSEWORKS_API_BASE/v1/proxy/orthogonal/run \
  -H "Authorization: Bearer $GOOSEWORKS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"api":"precip","path":"/api/v1/daily","query":{"latitude":"37.7749","longitude":"-122.4194","start":"2026-02-14","end":"2026-02-21"}}'

curl -X POST "https://api.orth.sh/v1/run" \

  -H "Authorization: Bearer $GOOSEWORKS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"api":"precip","path":"/api/v1/recent-rain","query":{"latitude":"37.7749","longitude":"-122.4194"}}'

Get Last 48 Hours

curl -s -X POST $GOOSEWORKS_API_BASE/v1/proxy/orthogonal/run \
  -H "Authorization: Bearer $GOOSEWORKS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"api":"precip","path":"/api/v1/last-48","query":{"latitude":"37.7749","longitude":"-122.4194"}}'

Response

All endpoints return GeoJSON FeatureCollection with coordinates in geometry and weather data in properties.

/api/v1/daily — properties.days[] array

• precip (number) - Total precipitation in mm
• rain / snow (number) - Rain and snow amounts in mm
• precip_probability (number|null) - Probability 0-100 (null for observations)
• precip_type (string) - rain, snow, sleet, or freezing_rain
• startTime (string) - ISO 8601 timestamp
• source (string) - observation or forecast

/api/v1/hourly — properties.hours[] array

Same fields as daily, plus:

• slr (number) - Snow-to-liquid ratio

/api/v1/temperature-hourly — properties.hours[] array

• temperature (number) - Temperature in °C
• startTime (string) - ISO 8601 timestamp

/api/v1/recent-rain — properties (single object)

• precip (number) - Total precipitation in mm
• rain / snow / sleet / freezing_rain (number) - Breakdown by type in mm
• precip_type (string) - Dominant precipitation type
• startTime / endTime (string) - Time window of the observation
• ago (string) - Human-readable time since last data (e.g., "2 hours")
• details (string) - Data freshness note

/api/v1/last-48 — properties (single object)

• precip (number) - Total precipitation in last 48 hours in mm
• rain / snow / sleet / freezing_rain (number) - Breakdown by type in mm
• precip_type (string) - Dominant precipitation type
• slr (number) - Snow-to-liquid ratio
• endTime (string) - End of the 48-hour window

Examples

User: "What's the weather in San Francisco this week?"

curl -s -X POST $GOOSEWORKS_API_BASE/v1/proxy/orthogonal/run \
  -H "Authorization: Bearer $GOOSEWORKS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"api":"precip","path":"/api/v1/daily","query":{"latitude":"37.7749","longitude":"-122.4194","start":"2026-02-14","end":"2026-02-21"}}'

User: "Will it rain in NYC tomorrow?"

curl -s -X POST $GOOSEWORKS_API_BASE/v1/proxy/orthogonal/run \
  -H "Authorization: Bearer $GOOSEWORKS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"api":"precip","path":"/api/v1/hourly","query":{"latitude":"40.7128","longitude":"-74.0060","start":"2026-02-15","end":"2026-02-16"}}'

User: "How much rain fell in Seattle recently?"

curl -s -X POST $GOOSEWORKS_API_BASE/v1/proxy/orthogonal/run \
  -H "Authorization: Bearer $GOOSEWORKS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"api":"precip","path":"/api/v1/recent-rain","query":{"latitude":"47.6062","longitude":"-122.3321"}}'

Error Handling

• 400 - Missing required parameters (latitude, longitude, or date range for daily/hourly)
• 422 - Invalid date format — must be YYYY-MM-DD
• precip_probability: null means the data is from observations, not forecasts
• source: "observation" = historical data; source: "forecast" = predicted
• All precipitation values are in millimeters (mm), temperatures in Celsius (°C)

Tips

• Convert city names to coordinates before calling
• Use current date for start, add days for end
• Date format must be YYYY-MM-DD
• recent-rain and last-48 don't need date parameters
