Pay it from Claude Code with a spending cap

  1. Add Burnbound's MCP server to Claude Code with your agent's key:
    claude mcp add burnbound --scope user -e BURNBOUND_KEY=<your-agent-key> -- npx -y @burnbound/mcp
    Get an agent key →
  2. Give the agent a policy that allows this host and caps each payment, for example:
    allowed hosts    x402.api.browser-use.com
max per payment  1 USD
daily cap        10 USD
network          Base (eip155:8453)
  3. Ask your agent to call this endpoint. It pays with fetch_paid, inside the policy: anything over the cap is blocked or waits for your approval, and nothing is signed for any other host.POST https://x402.api.browser-use.com/api/v3/sessions
