description: >-
  DAT does not publish numeric API rate limits on its public site, and its
  developer portal reference is gated behind an account login, so no official
  per-minute or per-day request caps could be confirmed during this build. A
  third-party integration write-up cites throttling around 100 requests/minute,
  but it is unclear whether this is a DAT-enforced limit or an integrator
  recommendation - treat it as an unconfirmed estimate. Access itself is gated
  by subscription and seat entitlements (load board seat + Connexion for loads,
  RateView seat + Connexion for rates) rather than by a published quota.
notes: >-
  Reconcile actual limits against the DAT Developer Portal once access is
  granted. Clients should implement exponential backoff with jitter and honor
  Retry-After on 429 responses.
