Protect an agent in one call
Create an agent, get a key, and call the Firewall before every payment or signature. Spend caps, drain protection and a kill switch — persistent per agent, every decision audited.
Free during early access. Sensible defaults: deny unlimited approvals, hold new counterparties, kill switch ready.
How it works
- Create an agent → receive a secret key (shown once).
- Before your agent sends a tx or x402 payment, POST it to
/api/v1/checkwith your key. - Warden runs the Guard verdict + your policy + live budget → returns allow / hold / deny.
- Your agent proceeds only on allow. Everything is logged.
