description: Air Products does not publish public API rate-limit documentation. Customer digital
  integrations (telemetry, MyAirProducts portal, EDI / order integrations) are governed by the gas
  supply agreement, and any throttling thresholds are set bilaterally with the customer's IT contact.
notes: No public rate-limit documentation; placeholders pending direct vendor confirmation.

# 2026-08-30 enrichment pass: verified by probe that Air Products publishes NO rate-limit documentation
# and no machine-readable contract in which limits could be declared. limit_count is an honest zero.
