How Credits Work
Credits are calculated based on the variables and geographic area your query touches.
credits = geographic_regions × time_months × variables # CAMS (0.1°): no2, pm2p5, pm10, o3 # ERA5 (0.25°): t2m, tp, blh, u10, v10 # VIIRS (0.005°): viirs (2020–present, monthly) # 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 variables = 1 # NO₂ only credits = 2 # Total: 2 credits # Example: NO₂ + temperature, Paris, full year geographic_regions = 2 # Paris bounding box time_months = 12 # Full year variables = 2 # no2 + t2m credits = 48 # Total: 48 credits # Example: Europe-wide, full year, 4 variables geographic_regions = 30 # Covers most of Europe time_months = 12 # Full year variables = 4 # no2, pm2p5, t2m, blh credits = 1440 # Total: 1440 credits
Tip: Narrow your geographic bounds and time range to use fewer credits.
Frequently Asked Questions
Do I need a credit card to sign up?
No. Create an account with just your email address and receive 500 free trial credits instantly — enough to run hundreds of real queries. A credit card is only needed if you want to buy more credits.
Do credits expire?
No. Credits never expire. Buy once, use anytime.
Can I buy more credits if I run out?
Yes. Purchase any package anytime — credits are added to your existing balance.
What happens when I run out of credits?
Queries return a 402 (Payment Required) status with your remaining balance. Purchase more credits to continue.
Is there a rate limit?
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.
What payment methods do you accept?
We accept all major credit cards via Paddle, including Visa, Mastercard, and American Express. Paddle acts as the Merchant of Record and handles VAT collection and compliance in all countries.
