API keys were designed for humans making API calls. AI agents make 100x more calls, spawning parallel fleets that share credentials. When one agent's key leaks, you can't revoke it without restarting all agents. No per-agent policy. No audit trail. No containment.
Every agent gets its own cryptographic identity. No shared secrets.
Set limits per agent. Rate limits that actually work at AI scale.
"Which agent made this call?" becomes answerable. Attribution guaranteed.
Shut down one rogue agent without touching the other 999. No cascades.

Why API Keys Fail at AI Scale
AI agents make 100x more API calls than humans and spawn parallel fleets that need credentials. Your API key infrastructure wasn't built for this:
AI agents need credentials that outlive individual sessions but refresh faster than quarterly. Designed for humans, breaks at agent scale.
Per-key limits designed for humans fail when one AI spawns 1,000 parallel connections. Your infrastructure can't distinguish between agents.
"Which AI made this call?" becomes unanswerable when keys are shared across agent fleets. No attribution, no accountability.
Shutting down one rogue agent means rotating keys for all 1,000 others. Cascade failures, service disruption, operational chaos.
No shared API keys. No rotation chaos. No cascade failures. Just ephemeral identity that scales to millions of agents.
Run Private.Me parallel to existing infrastructure. Zero downtime. Shift traffic at your pace. Deprecate keys when ready.
Full Control
Traditional Licensing Can't Handle On-Prem
Enterprises demand on-premises deployment (HIPAA, FedRAMP, ITAR). Vendors need payment control. Every existing licensing mechanism fails:
Copied, shared, or posted online. One license activates unlimited instances. No enforcement.
Government classified networks, industrial OT/ICS, healthcare HIPAA zones prohibit external connectivity. "Must connect to activate" eliminates enterprise buyers.
Docker containers, Kubernetes pods, VMware snapshots duplicate entire environments. One purchase, infinite deployments. Hardware dongles bypass vendor control.
Cloud-only vendors lose government, healthcare, finance contracts. On-prem vendors can't bill usage. Both sides walk away.
Code splits into 2 shares. Share 1 deploys to customer infrastructure. Share 2 delivered only when payment clears. Both required to execute. Neither useful alone. Information-theoretically guaranteed.
Government (FedRAMP, ITAR), Healthcare (HIPAA), Finance (SOC 2), AI vendors (on-prem models), Industrial OT/ICS (air-gapped control systems).
xID (Identity Infrastructure)
Both xLink and Xpass build on xID — the identity layer that makes keys obsolete. If you're building identity infrastructure directly, start here.
Ephemeral Identity
Per-verifier DIDs from XorIDA-split master seed. Cross-repo unlinkable. eIDAS 2.0 compliant.
Self-Converging Identity
K-of-N threshold from 8 signal types. ISO 24745 cancelable biometrics. No seed at rest.
AI Agent Identity
Verifiable DID per agent. No static tokens. Cryptographic accountability.

Zero-config pattern for AI agents, microservices, and IoT. Advanced users can use Agent.create() for full control.
Split. Distribute. Reconstruct.
Threshold secret sharing over GF(2). Any K shares reconstruct. Fewer than K shares reveal zero bits. Information-theoretically guaranteed.
