AI API in India: every model, billed in rupees
OpenAI, Claude, Gemini and more from India: one key, UPI, GST invoice, prices in rupees.
Why AI APIs are awkward to buy from India
Every major model provider bills in US dollars on an international card. From India that adds a forex markup on each payment, a separate account and invoice per provider, and 18% GST you have to self-assess under reverse charge because the seller is abroad. None of it is on the pricing page. The pay in rupees guide works through the arithmetic.
How Rapid Router handles it

One OpenAI-compatible API at https://rapidrouter.ai/api/v1 reaches Claude, GPT, Gemini, DeepSeek, Llama, Qwen, Mistral, Grok, Sarvam and 600+ models in all. You top up in rupees with UPI or a card, every recharge raises a GST invoice, and each request is billed at the provider's list price. The platform fee (5%) is charged once, when you buy credits.
