Order inference

Pick a model, write your prompt, and pay by the bite over x402. Approve a MetaMask permission once and DiemSum reuses it whenever a new quote fits the budget — no confirmation per prompt.

Wallet offMenu

Send a prompt to get a quote without a wallet. To pay, connect MetaMask Extension on desktop and choose a permission. DiemSum reuses a saved permission when a new quote fits its budget.

Recurring permissions stay in tab session storage and can auto-pay matching quotes from this browser without another MetaMask confirmation.Fixed permissions stay quote-scoped and are removed after the paid request succeeds.Fee-aware orders charge the seller's net plus a 0.5% DiemSum fee; the exact split is shown before each automatic payment.

No saved permission yet. Request a recurring budget once and DiemSum reuses it for matching quotes.

Recurring weekly budget (USDC)

Fee-aware orders draw the gross amount from this budget: the seller's net price plus a 0.5% DiemSum fee, floored to the smallest USDC unit. The gross goes to the DiemSum settlement router on Base, which pays the seller the net and the fee to 0x258a50c9dd8900fd727472fc25e49d251af046bf. Every quote shows its exact gross, net and fee before this tab's session key signs it; no extra click is asked.
