# SarangAI

> Unified AI gateway for developers: route 200+ AI models from one OpenAI-compatible
> endpoint with a single API key and a credit wallet. Ships with an official CLI
> (`sarangai-cli`), public web diagnostics tools, and per-token usage billing.

SarangAI (sarangai.id) is an OpenAI-compatible AI gateway. Developers create an API
key, point any OpenAI SDK, CLI, or IDE agent at the gateway base URL, and call
frontier and open-weight models (Claude, GPT-4o, Gemini, DeepSeek, Llama, Qwen,
Mistral, Grok, and more) while usage is billed in credits from a prepaid wallet.
The gateway adds automatic retry with exponential backoff, OpenRouter fallback
routing, equivalent-tier model cascades, and transparent per-model pricing.
