No card required
No card? You are on the cheap path already.
Here the card is the fallback: card-free routes have a 0% deposit fee and a $5 minimum; cards carry a 3.5% pass-through and a $20 floor.
Three ways in without a card

- RouteUSDC on SolanaYou needUSDCHowThe direct rail — zero hops, credited after finalityMinimum$5
A deposit is a plain send to an address — no wallet connection, no transaction signing — so a withdrawal straight from Binance, Coinbase, Kraken or any exchange works. Partial amounts accumulate; an exchange fee shaving cents off the send does not strand it.
If you want the card anyway
- RailAny crypto route aboveDeposit fee0%Minimum$5$10 becomes10.00
- RailCard (Stripe)Deposit fee3.5%Minimum$20$20 becomes19.30
The 3.5% passes through the processor’s ~2.9% + $0.30; the $20 minimum exists because a $5 card deposit would lose 8.8% to fees. Full arithmetic on the pricing page.

No withdrawalsCredits buy inference only.
Credits buy inference. They are not a withdrawable balance — we are not a money transmitter and do not want to become one, which is what keeps this cheap and KYC-free.
Credits never expireYour balance stays until you spend it.
Expiring credits is a dark pattern. Your balance sits there until you spend it.
$5 minimumSmaller sends are consumed by network fees.
Network fees eat anything smaller. That is the only floor, and it is deliberately low — the first bet on a stranger should be five dollars.

Accountless setup creates an API key and a permanent dashboard link. The link can replace a lost or rotated key; lose both and there is no personal recovery.
