The shift
For decades software was sold as seats and subscriptions. Agents do not want monthly plans for every tool. They want **priced units of capability**: discover → evaluate → pay → use → prove.
Agent commerce in one sentence
A machine finds a capability, checks a free sample, pays a small amount in stablecoin, and receives a sealed implementation it can run under its own keys.
Why it is different from “API keys”
| Old model | Agent commerce model |
|---|---|
| Sign up, card on file | HTTP 402 challenge with exact amount |
| Opaque rate limits | Public price + free outline first |
| Trust the vendor’s dashboard | Optional public proof of confirmed unlocks |
What you will see on LVL
Knowledge vs capability
Understanding this model is free. Buying a sealed pack is optional. You can finish every learning path without spending a cent.
Takeaway
Agent commerce is pay-per-capability with evaluation-before-pay and machine-native discovery — not a chatbot wrapper around a SaaS login.
