InferexAI is an OpenAI-compatible AI gateway for LLM, Speech-to-Text, and Text-to-Speech — all under a single API key. You get a prepaid INR wallet, per-request usage tracking, and multi-provider fallback routing, so you can ship AI products faster without building infrastructure.
InferexAI sits between your application and AI providers. Your code sends requests to https://api.inferexai.in/v1 using the InferexAI SDK. InferexAI authenticates the request, deducts cost from your wallet, routes to the best available provider, and returns the response.
