ACTIV Financial Systems
ACTIV Financial Systems is a provider of real-time and historical financial market data, best known for the ACTIV Feed consolidated multi-asset market data feed delivering global equities, options, futures, foreign exchange, and fixed income content with associated analytics and low-latency delivery to trading firms, banks, and financial applications. ACTIV Financial was acquired by Options Technology (Options-IT) in 2021 and its market data capabilities are delivered as part of the Options Atlas platform; www.activfinancial.com now redirects to www.options-it.com. A live public developer surface remains: the OnePlatform Web API (One API), a WebSocket/WebAssembly JavaScript API with a developer portal at weboneapi.activfinancial.com and 25 first-party packages on npm under the @activfinancial scope, with gateway hosts and credentials provisioned per customer rather than self-serve.
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 ACTIV Financial Systems the way a machine reads it — 3 machine-readable artifacts across 1 API, 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 — ACTIV Financial Systems scores 28.3/100 (emerging), with a separate agent-readiness read of 21/100 (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.

How we profile ACTIV Financial Systems
Each block below is one kind of artifact we hold for ACTIV Financial Systems. 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 1
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.

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.
