What is Pzero?
Pzero (PROTOCOL ZERO / PZERO) is an OpenAI-compatible inference proxy and a two-sided marketplace for expiring daily inference capacity.
Frontier First Inference. Minimum 20% off.
Buyers prepay USDC and get frontier models at a guaranteed minimum 20% off retail. Suppliers monetize perishable daily inference inventory (DIEM, $1 of inference per UTC day) by posting offers in a 30–80¢ corridor. A router clears the cheapest eligible supply for every request. Pzero takes a fixed 10% of cleared GMV.
Everything settles in USDC on Base. The protocol token, PZERO, trades on scale.farm.
Who it is for
- Buyers (we call them users): humans, integrators, and autonomous agents that consume inference. Fund once, set a minimum discount, and call a familiar
/v1/chat/completionsendpoint. - Sellers (infrastructure, like LP pools): holders of daily inference capacity who post offers and earn USDC on every clear.
- Operators: the protocol team running the router, settlement, payouts, and treasury.
What makes it different
- Economics first. The protocol promotes frontier models and throttles unprofitable micro-volume. It would rather run a smaller profitable market than a large unprofitable one.
- The corridor is a promise. The 80¢ cap mechanically enforces a minimum 20% discount on every cleared trade.
- A transparent fee. A flat 10% of gross USDC per clear: not an opaque bid-ask spread.
- Batched payouts. Sellers accrue per clear and are paid in one on-chain USDC transfer per batch, not per inference.
- Fail closed. Missing config, settlement failures, and unprofitable operations abort rather than silently degrade.
What it is not
- Not a hardware or self-hosting play.
- Not a bilateral order book: buyers never pick a seller; the router clears for them.
- Not "the cheapest inference." Pzero leads with frontier capacity at a guaranteed minimum discount.
