  U.S. Customs and Border Protection (CBP) is the federal law enforcement
  agency within the Department of Homeland Security responsible for
  apprehending individuals attempting to enter the United States illegally,
  stemming the flow of illegal drugs and contraband, protecting agricultural
  and economic interests from harmful pests and diseases, protecting
  intellectual property, and regulating and facilitating international trade,
  collecting import duties, and enforcing U.S. trade laws. CBP's primary
  trade automation systems are the Automated Commercial Environment (ACE),
  the Automated Export System (AES), AESDirect, the Advance Passenger
  Information System (APIS / eAPIS), and the Air Cargo Advance Screening
  (ACAS) program. Trade integrations are predominantly delivered through
  Electronic Data Interchange (EDI) messaging via ACE, with a small set of
  CBP web services (e.g., the AESDirect WebLink Inquiry API) exposed for
  programmatic use.

      The Advance Passenger Information System (APIS) collects pre-arrival
      and pre-departure manifest data on all passengers and crew members
      flown or sailed into and out of the United States. The eAPIS web
      portal allows commercial operators and private aircraft and vessel
      operators to create, manage, and submit APIS manifests. Bulk and
      partner integrations use UN/EDIFACT PAXLST and CUSRES messages over
      CBP-approved transmission methods.

      ACE is the U.S. Single Window through which the trade community
      reports imports and exports and CBP and Partner Government Agencies
      determine admissibility. Trade users access ACE via the ACE Secure
      Data Portal (a free web-based interface) and via ACE Electronic Data
      Interchange (EDI), which uses CBP-approved CAMIR/AESTIR messaging
      standards. The ACE Portal modernization program completed user
      access management migration in February 2025.

    description: >-
      AES is the system through which exporters file Electronic Export
      Information (EEI) for goods leaving the United States. AES is
      integrated with ACE and supports both EDI filings and the AESDirect
      web filing tool. AESDirect is the free web-based filing application
      offered by CBP to file EEI directly into AES.

      certification (test) and production environments for the API. This
      is one of the few directly exposed web APIs in CBP's trade portfolio.
