ZeroKeyCLI
AdSense for the Terminal
Problem
Developer-tool monetization is broken: subscriptions exclude casual users, terminals can't show ads, and crypto payments are too high-friction (wallet, gas, sign). Pay-per-use AI inference needs sub-cent settlement that disappears into a normal CLI flow.
Approach
x402 micropayments on Monad. The user runs the CLI, sees a 5-second ASCII ad, and during those five seconds two micropayments settle on-chain - advertiser pays the user $0.001 USDC, user pays the AI provider for one Claude API response. AdPool.sol manages advertiser deposits and verified impressions. No wallet setup, no gas, no subscription.

Tech decisions
x402 over plain ERC-20 transfers
HTTP-native payment standard composes cleanly with existing CLI tooling and HTTP middleware.
Monad over Ethereum mainnet
Sub-cent settlement is only economical on a high-throughput L1.
Ink.js terminal UI
Renders the ad inside the CLI itself - no browser handoff breaks the developer flow.

Advertisers don't pay for fake renders; users aren't blocked by adversarial advertisers.
