TRUST SIGNALS YOU CAN VERIFY TODAY
Not just an API proxy — a control plane that makes your AI stack more reliable, transparent, and flexible.
Keep your xAI account and pricing. Switch Grok models by changing one string — no migration, no rewrite.
Automatic failover, Grok model health tracking, and approved cost-aware routing keep requests moving without hiding what the gateway did.
See exactly where every token goes. Track usage by team, key, or model — and set limits before you get a surprise bill.
Build reliable multi-channel AI bots with automatic failover, multimodal support (vision, audio, PDF), and 8 Grok models. Grok API adds health-aware routing, cost visibility, and enterprise security to your OpenClaw deployments.
Grok API helps you compare baseline cost vs selected route, shadow-test cheaper approved Grok models, and prove savings in logs and analytics.
Pick a baseline Grok model, then approve cheaper Grok alternatives for the same workload. Start in shadow mode, then opt into live cost routing only for that basket.
Baseline: Grok 4.6 → Approved alt: Grok 4.1 Fast
On models whose vendor publishes a cached input rate, cache hits are billed at that rate, not at the full input rate. This matters most for agents and workflows with a long, repeated system prompt.
Where a cached rate is published it is typically 4-10x below uncached input
Request logs and Activity show baseline charge, selected route, realized savings, and shadow-mode recommendations so teams can verify what changed.
Logs: baseline vs selected vs saved, per request
Before: every request stays on one premium baseline model
After: baseline stays protected, a cheaper approved model runs in shadow first, then goes live for eligible flows
Illustrative: 20-35% lower model spendIllustrative example only. Actual savings depend on your approved model basket, traffic mix, and prompt shape.
Change one line. Get access to every Grok model with built-in reliability.
Swap your base URL to Grok API. Works with any OpenAI-compatible client — Cursor, Claude Code, LangChain, your own app.
Grok API applies model health, fallback rules, and your routing objective. If the first route fails, it moves to the next approved path automatically.
Same response format you already use. Plus usage tracking, cost visibility, and team controls — with zero extra code.

Connect Cursor, Claude Code, Windsurf, or other coding tools through Grok API.
Understand model pricing, BYOK fee semantics, and request-level billing visibility.
Unified AI infrastructure for solo founders — one API key, 8 Grok models, automatic failover.
Access every Grok model through a single unified API.
Learn how Grok API handles routing, billing visibility, BYOK, and tool compatibility.
No. Grok API is the infrastructure layer between your apps and xAI's Grok models. It keeps an OpenAI-compatible integration surface while adding routing, billing visibility, spend controls, and team governance.
Yes. Grok API supports bring-your-own-key workflows so teams can keep their existing xAI relationship and pricing while using Grok API for reliability, policy control, and shared visibility.
Yes. Teams can start with the OpenAI-compatible quickstart and use the dedicated vibe coding setup flow for Cursor, Claude Code, Windsurf, Cline, and similar tools.
Grok API applies model health checks, routing policy, and automatic failover before a request is sent. Teams can verify outcomes with direct xAI headers and request traces.
Grok API adds request-level usage tracking, spend visibility, auditability, and team controls so finance, ops, and engineering can manage shared AI traffic without building that layer themselves.
