Pricing per call

API calls draw from the same balance as the web app. Credits are only charged on success — failed requests are not billed. Top up or subscribe on the pricing page.

Requests that would exceed the balance return 402:

{
  "success": false,
  "error": {
    "code": "INSUFFICIENT_CREDITS",
    "message": "Insufficient credits. This request costs 10 credits."
  }
}
