Decide

Given a spending cap, Keryx compares public previews and prices, then explains which sources it buys or skips. Unspent budget stays with the buyer.

II
Cite

It reads purchased content and writes an answer with citations to sources that support its claims. It can also say when evidence is thin.

III
Settle

Eligible cited creators receive weighted USDC rewards on Arc testnet. The answer and public ledger distinguish settled, pending, and simulated payments.
