Sydney Airport
Sydney Airport Corporation Limited (ACN 082 578 809) operates Sydney Kingsford Smith Airport (IATA SYD, ICAO YSSY), Australia's principal international gateway, under private ownership by the Sydney Aviation Alliance consortium since its 2022 ASX delisting. In the travel distribution chain it is infrastructure rather than an intermediary - it sells no seats, holds no inventory, issues no PNRs, and sits outside the GDS and IATA NDC value chain entirely, monetising aeronautical charges, car parking, retail concessions and property instead. Its API posture is effectively nil - Sydney Airport publishes no developer portal, no API documentation, no OpenAPI, and no terms of use for machine access. Its public website is backed by undocumented JSON endpoints under /_a/ that return live flight and security wait-time data with no published contract, while its only credentialed partner surface, InfoSYD, is gated behind a ForgeRock OAuth 2.0 / OpenID Connect identity provider at id.syd.com.au and is restricted to airlines, ground handlers and on-airport tenants. The published terms of use expressly prohibit automated retrieval, scraping and indexing of the site, so there is public data but no public interface - and no documented exit path beyond an Australian Privacy Principle 12 personal-information access request.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Sydney Airport the way a machine reads it — 4 machine-readable artifacts, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Sydney Airport scores 14.2/100 (emerging), with a separate agent-readiness read of 15/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Sydney Airport
Each block below is one kind of artifact we hold for Sydney Airport. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Security Posture 3
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Scopes 1
OAuth scopes are the vocabulary of least-privilege access. Profiling them shows exactly what an integration — or an agent acting on a user's behalf — is allowed to do.

This is an independent, third-party profile of Sydney Airport, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
