Optus
Optus (Singtel Optus Pty Limited) is Australia's second-largest telecommunications carrier, wholly owned by Singapore's Singtel and headquartered in Macquarie Park, Sydney. It runs a national mobile network reaching over 99% of the Australian population, alongside NBN and cable broadband, satellite capacity inherited from AUSSAT, enterprise and government connectivity, IoT/M2M services, and consumer media. Its API posture is split in two. The only genuinely public, self-serve developer surface Optus operates is The Optus SMS Suite — an enterprise messaging platform white-labelled from New Zealand's Modica Group at sms.optus.com.au, which publishes open documentation, downloadable OpenAPI/Swagger definitions, a WSDL, delivery-receipt callbacks, and a free-trial signup. Everything else is partner-gated: the IoT Control Centre is a Cisco/Jasper platform behind a referral-coded starter kit, and Optus has no first-party network-API portal — developer.optus.com.au and api.optus.com.au resolve on Akamai but return HTTP 403 Access Denied. On network APIs Optus is a stated GSMA Open Gateway participant and an endorser of the Bridge Alliance API Exchange (BAEx), but as of this review no CAMARA API is callable from Optus directly; its route to developers runs through its parent Singtel's Paragon-powered BAEx and Aduna, not through anything Optus publishes itself.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles Optus the way a machine reads it — 25 machine-readable artifacts across 4 APIs, 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 — Optus scores 52.6/100 (developing), with a separate agent-readiness read of 28/100 (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 Optus
Each block below is one kind of artifact we hold for Optus. 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.
APIs 15
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.

ASYNCAPISecurity Posture 4
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.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.

This is an independent, third-party profile of Optus, 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.
