How the market works

01

Pick a sealed prompt

Browse work proven by paid runs. The prompt text itself stays encrypted in the vault — you're buying what it produces.

02

Fill in the blanks

Every prompt exposes a few simple fields: your topic, your code, your transcript. No prompt engineering required.

03

Get the output in seconds

A frontier model runs the sealed prompt on your inputs. The result is yours to keep — pay per run, never a subscription.
