name: Sunrise Sunset FinOps description: Financial operations guidance for teams consuming the Sunrise Sunset API. url: https://sunrise-sunset.org/api costModel: type: free price: 0 currency: USD notes: > The Sunrise Sunset API is entirely free with no paid tiers, no usage-based billing, and no account required. The only obligation is attribution — any application or product using the API must display a visible link back to sunrise-sunset.org. budgeting: estimatedMonthlyCost: 0 notes: > No direct cost to budget for. Teams should factor in any infrastructure costs on their own side for caching responses, as the API has no SLA and does not publish uptime guarantees. Caching sunrise/sunset values locally (they change slowly) reduces dependency on external availability. risks: - type: availability description: > No SLA is offered. Service is monitored via UptimeRobot at https://apistatus.sunrise-sunset.org/ but no uptime guarantee is provided. - type: rate-limiting description: > No published rate limits. High-volume or bursty traffic patterns may be blocked without notice. - type: compliance description: > Attribution is a contractual requirement per the terms of use. Failure to attribute may constitute a terms-of-service violation. recommendations: - Cache API responses client-side; sunrise/sunset values for a given lat/lng/date are deterministic and can be pre-fetched or stored. - Monitor the status page at https://apistatus.sunrise-sunset.org/ for service incidents. - Include visible attribution linking back to https://sunrise-sunset.org/ in any public-facing product.
