Assay

What the builder shipped

Pay the source, per use. When an AI answer draws on a source, Assay settles a fraction of a cent to that source, split by what the answer actually used. On Arc, in USDC. The gap it closes AI answers are grounded in sources, and those sources are read for free. The floor on payments (roughly thirty cents after fees) meant a single citation was never worth settling, so nobody did. Arc removes the floor: USDC gas, sub-second finality, payments as small as $0.000001
