Usage endpoints are served from https://api-meter.metrifox.com. Other API calls stay on https://api.metrifox.com.
Important Notes:
  • event_id (required) is required for idempotency: You generate a unique UUID per real event. This prevents duplicates if sent multiple times.
  • feature_key (this is required if there is no event_name): The unique key of the metered feature (from dashboard).
  • event_name (optional if feature_key is already provided): One of the event names configured on the feature (e.g., “api_request” or “image_generated”)
  • Include a timestamp (ms) when possible to aid ordering/debugging.
Example response: 
{
  "data": {
    "customer_key": "cust-mit7k5v8obzs",
    "quantity": 1,
    "feature_key": "feature_job_posts"
  },
  "message": "Event received"
}
