  No published request rate limits. The Supply Chain API tiers are differentiated by data refresh
  cadence (3 vs 5 crawls per week) rather than request quotas, and its contract is gated behind the
  Tools Portal login so any per-key limit could not be read. The self-hosted reference agents declare no
  429 or rate-limit headers.
