description: OneAtlas APIs enforce per-token rate limits at the API gateway and quota limits at the product level (AOI square-kilometre or order count). Exact numeric ceilings are not published on the public portal landing page and depend on the underlying subscription or pay-per-order contract.
notes: Per-second / per-minute gateway limits are not publicly advertised; product quotas (sqkm / orders) are set by contract. Confirm during onboarding.
