Zonos is a cross-border trade technology company headquartered in St. George, Utah, United States, that sells customs and trade compliance as an API. Its products calculate landed cost (duty, tax, brokerage and carrier fees), classify goods to HS codes with AI, screen parties and items against restricted and denied lists, rate and label international parcels, generate customs documents, submit postal PDDP declarations to destination posts, and file CBP entries for consolidated air consignments. It sits in the middle of the chain — between merchants, carriers, postal operators and freight consolidators on one side and customs authorities on the other — and is one of the few organizations in this tier whose integration surface is genuinely public rather than a customer-contract portal. A single unified GraphQL endpoint at https://api.zonos.com/graphql answers unauthenticated introspection (1,396 types, 170 queries, 153 mutations, harvested 2026-07-30), the reference is browsable without login at https://zonos.com/developer, and a legacy REST v1 layer remains documented but is declared end-of-life. Calling anything real still requires a credential token from the Zonos Dashboard, which is self-serve only for Shopify merchants; every other platform is routed through sales and an account agreement.
Zonos publishes 6 APIs on the APIs.io network. Tagged areas include Logistics, Supply Chain, United States, Customs, and Trade Compliance.
Zonos’ developer surface includes documentation, API reference, authentication, pricing, signup flow, developer portal, engineering blog, and 12 more developer resources.
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.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/zonos: open an issue to ask a question, or submit a pull request to add artifacts.
