Credits are calculated based on the amount of data your query touches.
credits = geographic_regions × time_months × pollutants # Example: Paris NO₂, January 2023 geographic_regions = 2 # 48.5–49.2°N × 2.0–2.8°E → 2 regions time_months = 1 # January 2023 only pollutants = 1 # NO₂ only credits = 2 # Total: 2 credits # Example: Europe-wide, full year, both pollutants geographic_regions = 30 # Covers most of Europe time_months = 12 # Full year pollutants = 2 # NO₂ + PM2.5 credits = 720 # Total: 720 credits
Tip: Narrow your geographic bounds and time range to use fewer credits.

No fixed rate limit. When the server has headroom, all requests proceed immediately with no restrictions. Under heavy load, Jiskta uses fair-use throttling: each API key automatically receives an equal share of capacity. A well-behaved script making a few concurrent requests will never be throttled. Only keys flooding dozens of simultaneous requests are briefly slowed when others are waiting. If you receive a 429, retry after 500ms.
We accept all major credit cards via Stripe, including Visa, Mastercard, and American Express.
