Platform

Buy. Sell. Verify. Settle.

One market that matches unused API capacity with the apps that need it.

Buy

One endpoint, every frontier model. Each request fills at the lowest live offer with automatic failover.

Sell

List surplus credits at your own ask. When you're the best offer, traffic routes to you.

Verify

Every live offer gets an hourly test prompt. Offers that stop answering correctly leave routing until they pass again. It is a behavior check, not proof of identity: how checks work.

Settle

Per-request ledger. Buyers see the exact price of every fill; sellers get paid daily in USDC.

How it works

From your first request to the cheapest fill, in three steps.
