  title: Nephia API
  description: >-
    The brand-monitoring API. Create a **Query** and it polls the live Sources
    (X, Reddit, Youtube, TikTok, Bluesky, Hacker News, Mastodon, Lemmy, GitHub,
    Product Hunt, Stack Overflow, RSS, AI answers — and Vinted) on an interval,
    keeps what matches, reads each mention for sentiment and intent, sorts it
    into your buckets and answers your own agent step over it. Read the result
    back as **mentions** — `GET /v1/mentions` across the whole Account, or per
    Query — or have it pushed to you as signed webhook events and delivery
    channels. A search can carry several terms at once, OR'd into one upstream
    request at one tick's cost. Authenticate with an API key on your Account.
    Monitoring is sold as a subscription — queries, terms, freshness and AI —
    with credits as the meter underneath; credit packs are overflow and never
    change a limit. Reading your own mentions is free; the semantic search mode
    and the AI passes are what meter. Request quota is per Account (all API keys
    share one bucket), by Plan: Free 60/min, Solo 350/min, Growth 700/min, Pro
    1200/min.
