Frequently asked questions

What is a credit?

A credit is one unit of usage. You pay per token for model usage — roughly 1 credit per 1,000 input tokens and 2 per 1,000 output tokens — so the balance you add is spent only when agents actually do work.

Do I need to subscribe?

No. Tubelight is pay-as-you-go — top up any amount when you need more, and the balance never expires.

How are credits priced?

Credits cost ₹0.10 each. The minimum top-up is ₹500, and you can add any amount above that — every rupee adds 10 credits.

How do I pay?

Top-ups run through Razorpay — UPI, cards, and netbanking are all supported at checkout.

What happens when I run out of credits?

You’ll see a 402 prompt and can top up right from the app with any amount.

Is uploading a document free?

Yes. Uploading, parsing, and indexing a PDF is free — you’re only charged for the model tokens that actually answer or generate.

Do I get any free credits?

Yes — every new account starts with 100 free credits, enough to try the agents before adding funds.
