Pricing & credits

Provider list prices, passed through + a transparent fee. No hidden costs.

Pricing formula#

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                                              # KRW rate, auto-refreshed daily 09:00

Per-model USD list prices are available via GET /v1/models, and today's applied FX rate via GET /v1/fx-rate at any time. The cost field on every response shows the exact FX rate and markup applied.

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 you top up credits (all payment methods). You can verify the applied markup in the cost.markup_rate field of the API response.

There is no markup on token prices (0%). A 3% platform fee applies at top-up — that is the entire service cost. Since everything is fixed in KRW, there is no FX volatility risk.

FX rate#

The rate is refreshed automatically every day at 9:00 AM from the Korea Eximbank base rate. If a refresh fails, the last valid rate is kept.

Credits#

• Minimum top-up amount: ₩5,000
• The estimated cost is held upfront at request time and settled against actual usage on completion
• Failed calls release the full hold — no charge
• A monthly budget limit can be set per API key (returns 402 when exceeded)

Tax invoices#

Business-verified accounts automatically receive an electronic tax invoice on every top-up. Issuance covers top-ups made after you complete business verification — past top-ups are not issued retroactively. Complete business verification first.
