Pricing & credits

New accounts get 100 bonus credits, and you can earn up to 400 additional credits through activities such as the sign-up survey, your first API call and five days of use. Your first top-up earns a separate reward of 10% of the credit you top up (capped at 5,000 credits). See coupons & bonuses for details.

Pricing formula#

final_KRW = (in_tokens/1M * in_price + out_tokens/1M * out_price)  # USD list price
          * 1.00                                                 # model fee: 0% (pass-through)
          * fx_rate                                              # applied rate: base rate + 0.5% FX markup, refreshed about every 10 min

Per-model USD list prices are available via GET /v1/models, and the display FX rate via GET /v1/fx-rate at any time. A call's cost appears in the cost field or the X-Cost-* headers of the response; see the API index for where each applies.

Service fee#

We don't mark up token prices (0%) — the provider's list price is billed as-is. A 3% platform fee applies when an account without a subscription tops up prepaid credits. Top-ups by subscribed accounts carry no platform fee. You can verify the applied markup in the cost.markup_rate field of the API response.

FX rate#

The rate applied to billing is the base exchange rate plus an FX markup of 0.5%, and it is refreshed about every 10 minutes. The rate returned by GET /v1/fx-rate is a display value fixed every day at 9:00 AM.

Credits#

1 credit is worth ₩1. For an account without a subscription, the amount charged at top-up includes a 3% platform fee and 10% VAT. For example, a 10,000-credit top-up by such an account adds a ₩300 fee and ₩1,030 VAT, for a total of ₩11,330.

• Payment: Korean cards (KRW). Minimum top-up: 5,000 credits
• A call that fails before any response is sent is not billed. If a streaming response fails midway, the tokens already sent are billed
• A daily, weekly, or monthly budget limit can be set per API key (returns 402 when exceeded). Weekly is a rolling 7 days (UTC)
• A monthly token limit can be set independently (combined input+output)

Tax invoices#

Electronic tax invoices are issued on request after Korean business verification. Top-ups made before verification are not issued retroactively.
