Claude writes a script. The agent pays for every line from its own on-chain balance and goes silent the instant the money runs out. Pick a budget and run it: overspend isn't discouraged here — it's impossible.
Each spoken line settles on Casper for 0.10 X402. Choose how much the agent gets to start with.
What just happened
It points at our endpoint instead of the provider, holding a Casper key and a token budget.
The rail answers 402 with a per-line price in our CEP-18 token.
The agent signs an x402 authorization; the facilitator settles it on Casper in seconds.
When the balance can't cover the next line, the call simply fails. No overdraft, no surprise bill.
This page simulates the budget logic so you can see the wall without funding a wallet. The real rail does exactly this on Casper testnet — every line becomes a final on-chain settlement. See it for real in the developer dashboard or read the integration on GitHub.
