GenAff — AI API Gateway Platform [Currently Building]

Making AI affordable — a unified API gateway that lets developers start using AI APIs with as little as ₹10.

GenAff is an AI API gateway platform designed to make AI usage affordable and accessible for developers. Most AI platforms require a minimum $5–$10 top-up, creating a barrier for students and developers who want to experiment with AI APIs. GenAff solves this by enabling developers to start using AI APIs with very small amounts (₹10) through a unified API. The platform features multi-provider routing (OpenAI, Gemini, DeepSeek), wallet-based billing with micro-transactions, dynamic request routing with provider abstraction, API key management, per-request cost tracking, rate limiting, and a developer dashboard with an API playground.
