How it works

  • One credential. Send your API key in the X-API-Key header on every request. There is no request signing — see Authentication.
  • Plan-based access. Which data domains you can call and how much you can call them are governed by the subscription plan attached to your key — see Plans & features.
  • Weighted quota. Each endpoint consumes a weighted amount of your per-minute budget; every response returns X-RateLimit-* headers — see Rate limits.
  • Consistent envelope. Every response is wrapped in { success, statusCode, data, meta }.

}
