The arithmetic

List price × 0.02

We take the vendor's published per-token price and charge 2% of it. Nothing else: no platform fee, no markup on cached tokens, no rounding up to the cent. Your balance is kept to a millionth of a cent.

Questions

Before you pay

Why is it this cheap?

Our cost to serve these models is far below the public list price, and we pass most of that on. The price is pegged to the vendor's list price: when they cut, we cut.

Do you keep my prompts?

No. We store request metadata needed for billing — model, token counts, cost, latency, status — and never the prompt or completion text.

Which coins and networks?

USDT · Tron, USDC · Solana. Stablecoins on Tron, Base or Solana have the lowest network fees.

What if I send the wrong amount?

The exact amount shown is what identifies your payment, so send it to the cent and digit. A transfer that matches no open order is not lost: write to support with the transaction id.
