Usage-Based Billing

Usage is measured based on API requests and data delivery. This may include:
  • Standard API requests (JSON endpoints)
  • Data-heavy endpoints (radar, lightning, etc.)
  • Binary responses (PMTiles, images, etc.)
Different endpoints may have different usage weights depending on resource intensity.
Always refer to individual endpoint documentation for specific usage considerations.

​
Rate Limits

All plans include rate limiting to ensure system stability. Each response includes headers such as: 
X-RateLimit-Limit
X-RateLimit-Remaining
X-RateLimit-Reset
Higher tiers include higher rate limits.
