name: League
description: 'League is a Toronto-founded (2014) healthcare platform company whose Health OS powers consumer healthcare experiences
  for payers, providers, consumer health brands and employers, and which now positions itself as a healthcare-grade agentic
  experience platform shipping pre-built AI Agent Teams for benefits navigation, care navigation and health coaching. Its
  data platform is built on the HL7 FHIR standard, using FHIR resources such as QuestionnaireResponse and CarePlan to model
  both integrated healthcare data and member-generated data across a longitudinal health record. League runs a Developer Program
  that gives contracted customers SDKs, a server-driven UI framework, back-end extensions and data integrations for embedding
  League into existing applications. The platform API is served from a live Kong-fronted gateway at api.league.com that answers
  with the JSON:API media type, but neither the API reference nor any machine-readable contract is published publicly: the
  documentation portal sits behind an Auth0 login and developer access is granted through a contact-sales form.'

  description: The League platform API, served from the Kong-fronted gateway at api.league.com. Unauthenticated requests return
    an RFC-shaped JSON:API error document (content-type application/vnd.api+json) and carry x-ratelimit-limit-360 / x-ratelimit-remaining-360
    response headers, confirming a live, rate-limited production gateway. Access is provisioned per customer as API Keys under
    the League Developer Program Terms; no public API reference or machine-readable contract is published.

  detail: 'League runs a live production API — api.league.com answers with the JSON:API media type behind Kong 3.8.0 and enforces
    an advertised 10,000-request/360-second rate limit — but publishes no machine-readable contract anywhere: docs.league.com
    302s to an Auth0 universal login, developer.league.com (formerly a ReadMe hub) now 301s to the marketing site, and developer
    access runs through a 48-hour contact-sales form, so every artifact here is probed from the live gateway or searched from
    public policy pages rather than read from a spec.'
