  Auto.dev enforces a per-second request rate limit that scales with the
  account plan: Starter is limited to 5 requests/second, Growth to 10
  requests/second, and Scale to 50 requests/second. The Starter tier also
  caps included usage at 1,000 API calls per month, after which access is
  limited; Growth and Scale have no cap on call volume. The listings
  endpoint additionally caps results per page by plan (Starter 20, Growth
  100, Scale 500).
notes: >-
  Verify current per-second limits and the Starter monthly call cap on the
  Auto.dev pricing page during reconciliation; limits change as accounts
  move between tiers.
