Infinite Athlete
Infinite Athlete is a sports technology company that brings together leading companies in performance biomechanics and real-time video to deliver data-driven, actionable insights for elite athlete evaluation, development, health, and safety. Its work spans athlete performance frameworks, biomechanics research and development, a real-time video and data capture technology platform, facility design and hardware installation, sports operational efficiency, and equipment/facility/surface analysis and certification for major leagues and teams. Its developer-facing product is FusionFeed, a sports and performance data API (REST, GraphQL, and the proprietary FQL query language) built on the Tempus Ex platform that exposes schedules, rosters, official and automated statistics, telemetry, video feeds, and virtual camera data. The developer platform is currently invite-only. Infinite Athlete is backed by a16z and has been recognized among the "10 Most Innovative Sports Tech Companies" by Sports Business Journal.
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 Infinite Athlete the way a machine reads it — 4 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 — Infinite Athlete scores 25.1/100 (emerging), with a separate agent-readiness read of 20/100 (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 Infinite Athlete
Each block below is one kind of artifact we hold for Infinite Athlete. 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.

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.
