Rate limits

Limits are enforced at the CloudFront edge by API key (or agent token). Limits are per-minute and per-day; whichever fires first applies.

Every response carries X-RateLimit-Limit, X-RateLimit-Remaining and X-RateLimit-Reset (epoch seconds). On a 429, honour Retry-After in seconds.

Backoff guidance

• Cache aggressively — every endpoint has a published TTL via X-Cache-TTL.
• Coalesce identical requests inside your service.
• Use /v1/intel/hex/:h3 instead of 4 separate calls when possible.
