ALTER Identity

Summary
This connects AI agents to TrueAlter's psychometric identity verification system, letting you confirm you're talking to a verified human rather than another bot. It exposes identity queries over MCP with x402 micropayment integration, so agents can programmatically verify identities during interactions. You'd reach for this when building AI systems that need to distinguish between human and AI participants, or when you need cryptographic proof of human identity in agent workflows. The streamable HTTP transport makes it straightforward to integrate, and the micropayment model means you pay per verification rather than maintaining subscriptions.
