The Enterprise
LLM Platform.
Unified API for all models, intelligent routing, and AI Model Insurance — built for teams that need reliability, observability, and cost control.
Unified API
One API key for every model — Claude, GPT, Gemini, and more. No juggling providers, no fragmented billing. Plug in once, access everything.
Intelligent Routing
Automatically route requests to the best model for cost, latency, or quality. Smart fallback ensures zero downtime when a provider goes down.
AI Model Insurance
Eliminate hallucination risk with built-in model insurance. Automated validation, output guardrails, and SLA-backed accuracy guarantees.
Five Tools, One Key
Every AI coding tool.
Unified.
One Zenn API key works across all five tools. Full API call logs, real-time cost and usage dashboards, and per-model performance analytics — at up to 50% off.
OpenClaw
The fastest-growing AI agent. Configure Zenn as your provider — Claude Sonnet/Opus, Codex, and Gemini 3.0 Pro through one lobster.
