Mermail x402 Agent
Security checks across malware telemetry and agentic risk
Overview
This skill is a disclosed payment workflow for user-approved x402 service calls, with strong limits around authorization, credential handling, and settlement claims.
Install only if you intend to let an agent help with user-approved x402 payments through Mermail PayBox. Review the spend preview carefully, make sure the origin/resource and required_charge match your request, and do not paste signing keys, payment proofs, or credentials into chat.
