Steadfast Group
Steadfast Group Limited (ASX:SDF) is the largest general insurance broker network and the largest group of insurance underwriting agencies in Australasia, headquartered in Sydney, Australia. It is a broker-intermediary rather than a risk carrier: the Steadfast Network comprises 414 independent brokerages placing approximately $12.7 billion in gross written premium, alongside 31 underwriting agencies writing roughly 100 products across business pack, liability, professional indemnity, cyber, construction, marine, aviation, farm, strata, motor and home and contents lines, plus complementary businesses covering premium funding (IQumulate), life insurance, workplace risk, legal and compliance. Its trading technology is the Steadfast Client Trading Platform (SCTP), launched in 2009, which lets network brokers send one question set to a panel of insurers for instant comparative quotes and which transacted over $1.5 billion in GWP in CY25 across 9 insurer lines and 23 connected partners; SCTP and the INSIGHT policy management platform are being consolidated into a broader "Steadfast Apps" broking platform. API posture, recorded honestly - Steadfast Group publishes NO developer portal, NO API documentation and NO specification of any kind, and a full crawl of all 311 pages in the public sitemap returned zero references to a developer portal, REST API, OpenAPI or Swagger. Two genuinely machine-readable surfaces nonetheless exist and neither is announced anywhere. The consumer Flood Risk Tracker is backed by a public, anonymous, undocumented JSON API that resolves Australian addresses against the national G-NAF dataset and returns Swiss Re river-flood and storm-surge risk layers, returning RFC 9457 problem details and advertising api-supported-versions 1.0; the OpenAPI in this record was derived from the tool's own client JavaScript and from live probes. Separately, idp.steadfast.com.au is an Okta-hosted OpenID Connect provider publishing a complete anonymous discovery document with PKCE S256 and DPoP, though client registration is commercially gated. The commercial surfaces remain closed: broker.steadfast.com.au is a credentialed broker login wall, and api.steadfast.com.au and api-sf.steadfast.com.au are live but undocumented hosts returning HTTP 403 at the root. Insurer and partner connectivity into SCTP is arranged commercially, not through self-serve onboarding. The company's most notable standards signal is governance rather than implementation: founder, Managing Director and CEO Robert B. Kelly AM is Chair of the ACORD Board in New York, though no ACORD, AL3, ACORD XML or NGDS implementation detail is published anywhere on the public site. Australia has the legal machinery for open insurance but no live obligation - the Consumer Data Right was designated to extend to general insurance and then deferred, so no regulatory forcing function pushes a broker network of this scale toward a public API.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Steadfast Group the way a machine reads it — 7 machine-readable artifacts across 2 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 — Steadfast Group scores 39.1/100 (thin), with a separate agent-readiness read of 58/100 (agent ready). 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.

How we profile Steadfast Group
Each block below is one kind of artifact we hold for Steadfast Group. 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 2
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.

MCP Servers 1
Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.
Model Context Protocol servers that expose these APIs to AI agents.
Security Posture 2
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.
OAuth scopes governing access to this provider's APIs.
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.
