Caterpillar Rate Limits
The Cat Digital Marketplace gates API access behind a developer-subscription flow on digital.cat.com. Per-second / per-minute limits are not published in the public catalog overview and are surfaced to the subscriber once an API product is added to a developer's account. Limits typically vary per API product and per Cat Connect / VisionLink subscription class.

Subscription-scoped limits
Limits are evaluated per Cat Digital subscription. Different API products in the catalog apply different per-product limits.
Backoff
On 429 / 503, retry with exponential backoff and jitter; honor Retry-After when supplied.
Telemetry cadence
VisionLink-derived data is updated on the platform's collection cadence; polling faster than the upstream refresh window wastes quota and adds load without surfacing new data.
