$ why

Wholesale rates. No surge. No surprise.

Three things that beat the official APIs and resellers.

Up to 40% off list

We pass on wholesale token discounts. Same Claude, same GPT-4o, same Gemini — just cheaper.

99.95% uptime

Multi-provider failover routes around any single outage. Your code never sees a 503.

Drop-in replacement

Anthropic & OpenAI SDKs work as-is. Change one URL. Streaming, tools, vision — all of it.

$ models

Every model worth using.

Switch models with a string. No new SDK, no new auth.
