Pay for the answers you get
Add credit with USDC on Base. Each answer takes exactly what it cost, and nothing else. One model is free to try.
Input and output are per million tokens; a token is about three quarters of a word. A typical answer is about 1,000 tokens in and 700 out. Free answers come from one daily pool. When it's busy, wallets that have added credit keep theirs, and the others get fewer; before each free answer your browser solves a small puzzle, which slows down scripts, not people.
No subscription
Top up when you like and spend it at your own pace. Credit belongs to your wallet's account.
Pay for what's written
If an answer fails, it's free. Stop one early and you pay only for the part you got.
Every cent on a receipt
Each answer's receipt shows exactly what it cost, including any web searches (about a cent each), next to what it sent and where.
What $10 gets you
Add it in USDC on Base from the wallet you sign in with: that's how a payment finds your account without a name or an email. It shows up in about a minute.
About how many typical answers, by model
A typical answer is about 1,000 tokens in and 700 out, our fee included. Long chats and web searches cost more. Payments are public on Base, so use a wallet that isn't tied to you; we check paying wallets against the US sanctions list.
