Provn

A plan buys limits. Compute costs the same.

Every plan meters at the gateway, caps per key and signs every call. Pro and Scale raise rate limits, keep usage history longer and unlock signed audit packs. The fee comes out of the same prepaid balance your compute draws from.

Compute costs the same on every plan.

Model prices and the sandbox rate stay fixed whichever plan you pick. The cost on each receipt is the amount your balance pays.

Privacy comes with every plan.

Free, Pro and Scale share the same receipts, metering and privacy contract. A plan changes limits and retention, and leaves the handling of your prompts as it is.

Paid from your prepaid balance.

You fund one balance with ETH on Robinhood Chain, and compute and plan fees both draw from it. A new account starts with a one-time $1.00 credit.

30-day periods, no proration.

Subscribing takes the monthly fee from your balance and starts a 30-day period. Switching plans mid-period doesn't prorate.

Cancel and keep the rest of the period.

Cancelling stops the next renewal. Your plan stays in place until the current period ends.
