pricing

pay per token. nothing else.

no subscription, no minimum spend, no surprise invoices. fund with USDG or earn daily credits by holding $IWTF. you only pay for what you use.

overview

inference.wtf bills per request after completion. input and output tokens are priced separately per model. prices below are per million tokens and include our gateway markup.

no subscription

create keys free. pay only when you call the api.

no minimum

top up any amount in USDG. credits never expire.

holder credits

hold $IWTF for a daily allowance — drawn before paid balance.

how you pay

two balances, one wallet. allowance is always consumed first.

  • purchased · USDG — top up via x402 at 1 USDG = $1.00 credit. paid credits never expire and cover any model.
  • allowance · $IWTF — recurring daily credit from your on-chain $IWTF balance. linear formula, hard cap, no rollover.

when both balances hit zero, the api returns 402 payment required with top-up instructions.

$iwtf allowance

holding $IWTF grants a credit allowance each window. the formula is simple and capped — no tier gaming, no rollover.

allowance = min(balance × 0.0016, $5 cap)

example: 1,250 $IWTF → $2.00 allowance this window (under the $5 cap). unused allowance resets when the window ends.
