GraphQL AccessALPHA

Access Daylight Duration Calculator through GraphQL to combine it with other API calls in a single request. Query only the daylight duration calculator data you need with precise field selection, and orchestrate complex data fetching workflows.

Credit Cost: Each API called in your GraphQL query consumes its standard credit cost.

POST https://api.apiverve.com/v1/graphql

query {
  daylightduration(
    input: {
      latitude: 40.7128
      longitude: -74.006
      date: "2024-06-21"
    }
  ) {
    date
    location {
      latitude
      longitude
    }
    condition
    description
    sunrise
    sunset
    daylight_duration {
      total_minutes
      hours
      minutes
      formatted
    }
    day_of_year
    is_valid
  }
}

Note: Authentication is handled via the x-api-key header in your GraphQL request, not as a query parameter.

CORS Support

The Daylight Duration Calculator API accepts cross-origin requests from any origin, so it can be called directly from browser-based applications without a proxy. See CORS support →

Rate Limiting

Daylight Duration Calculator requests are throttled per minute on the Free plan and unthrottled on paid plans. Exceeding the limit returns 429 Too Many Requests; rate-limit usage is reported in the X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset response headers. See per-plan limits and best practices →

Error Codes

The Daylight Duration Calculator API uses standard HTTP status codes — 200 on success, 400 for invalid parameters, 401 for missing or invalid keys, 403 for insufficient credits, 429 for rate-limit exhaustion, and 500/503 for server-side issues. Each error response includes an X-Request-ID header you can quote when contacting support. See full error handling guide →
