# Agentic Interaction Trust Gate

> External application-level evidence gate for agent workflows. Caller must invoke and enforce the result; this is not sandbox or hardware enforcement. Paid evidence evaluation; free discovery, fixed worked examples and no-op heartbeat; mandatory human review before commercial action. No independent factual verification or clearance. Zero-trust evidence review for agent-to-agent interactions: before a counterparty agent transacts or invokes a capability, check what identity and authority evidence is present. An A2A-compatible evidence-readiness gate for agent-to-agent and agent-mediated actions across A2A endpoint, MCP tool, checkout, account, and API surfaces. Bring the actor's identity claim, target surface, requested action, and dated evidence; get trust-routing triage, the missing source categories, evidence gaps, watch-next indicators, a decision-readiness score, a trust signal, and human-review routing. Evidence-readiness only — not identity verification, authentication, or transaction authorization.
