Build spending caps and approval rules for x402-capable agents.
About Spend Fence
Spend Fence is a free, browser-only builder for portable spending policies for autonomous agents. Set a per-call cap, daily ceiling, human-approval threshold, network, and HTTPS host allowlist, then copy or download the resulting JSON and setup instructions. It does not connect to a wallet or enforce the policy; operators must apply the generated settings in their own payment client.
