description: Evolv AI (formerly Sentient Ascend) is an experience optimization and autonomous experimentation platform that
  continuously tests and personalizes digital experiences using machine learning. Its Participant API and official client
  SDKs for JavaScript, iOS, Android, PHP and React allocate visitors to experiment variants, deliver optimized configurations,
  and ingest behavioral events so AI-driven optimization can evolve web and app experiences without manual A/B-test management.
  Enterprises use Evolv AI to automate conversion-rate optimization and personalization across their digital properties.

- name: Evolv Participant API
  description: The Evolv Participant API is the runtime edge API the client SDKs call to fetch a participant's experiment
    configuration and allocations for an environment, and to ingest context and behavioral events (the "beacon"/data endpoint).
    Requests are keyed by a public environment id and a participant uid; the API is versioned in the URL path (v1). Documented
    as a public Postman collection at developers.evolv.ai.

  note: Found and saved Evolv's own published Postman Collection v2 (7 operations, saved response examples) at developers.evolv.ai
    — the machine-readable contract earlier rounds had missed. Probed the live Participant API for its real error envelope
    and header behaviour. Recorded that the evolv.ai marketing site now answers HTTP 401 (Squarespace "Private Site") on every
    path while the API, docs and console stay live.
