Free to adopt. Pay to run a fleet.
Guard is free for every agent — that is how Warden becomes the default. The Firewall is how teams running many agents pay: spend control, drain protection and audit as a service.

Base · crypto onlyConnects your wallet (MetaMask / Coinbase Wallet), switches to Base, and sends USDC directly. No custody, no card.
Usage-based API (optional)
*For heavy programmatic use, the API can switch to pay-per-call over x402: a generous free tier per day, then ~$0.01–0.02 per call in USDC on Base. Off by default — the public guard stays free. The real revenue is the Firewall, where the value (and the risk) lives.
