Pay per request, strictly in Rupiah

Your IDR top-up is ready to use immediately. Each request reserves a worst-case estimate first, then settles against actual usage: the remainder is refunded to your balance instantly.

  • IDR Flexible top-ups from Rp10,000 to Rp10,000,000 via iPaymu.
  • Rp0 Requests that fail before processing cost exactly Rp0.
  • AUDIT All reservations, settlements, and refunds are auditable in your usage history.

Request lifecycle:

1. Reserve Max token estimate
2. Execute Call the AI model
3. Settle Exact debit + refund
