Customs and Border Protection

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.

Customs and Border Protection is listed with 5 APIs on the APIs.io network. Tagged areas include ACE, ACAS, AES, Borders, and Cargo.

Customs and Border Protection’s developer surface includes YouTube channel, engineering blog, and 15 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Government & Public Sector regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Machine-Readable Auth +10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey)
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.
