Pricing & Billing

How usage is metered and deducted from your prepaid nabh credits.

Prepaid nabh Credits

nabh.cloud is prepaid. You buy nabh credits in Indian Rupees (₹) — 1 nabh credit = ₹1, fixed — and each request deducts its usage charge from your credits. Every rate on this site is quoted in ₹, so a rate of ₹0.01 per 1K tokens deducts 0.01 credits per 1K tokens. New accounts get 50 free credits on signup. When your credits run out, requests are declined with INSUFFICIENT_BALANCE rather than billed — you can never overspend.

How Charges Are Calculated

Text and embedding usage is billed per 1,000 tokens, split into input and output rates. The formula is:

cost = (input_tokens  / 1000 × input_rate)
     + (output_tokens / 1000 × output_rate)

# Example — gpt-oss-20b (₹0.01 in / ₹0.03 out per 1K)
# 1,000 input + 300 output tokens
raw = (1000/1000 × 0.01) + (300/1000 × 0.03)
    = 0.01 + 0.009
charge = ceil(raw in paise)
       = ₹0.02

Image models are billed per image and speech models per minute of audio. See the full model catalogue for every rate.

Cost Visibility

Every response tells you exactly what it cost. The JSON body includes cost_inr and balance_inr, and the balance is also returned as a header. These fields keep their _inr names, but the values are credits: cost_inr is the credits this request used and balance_inr / X-Balance-INR is your credit balance (1 nabh credit = ₹1).

// Non-streaming responses include cost in the JSON body:
{
  "choices": [ /* ... */ ],
  "usage": { "prompt_tokens": 1000, "completion_tokens": 300 },
  "request_id": "req_8f2c...",
  "cost_inr": 0.02,
  "balance_inr": 49.98
}

// Every response (streaming or not) also carries these headers:
X-Request-ID: req_8f2c...
X-Balance-INR: 50    // balance before this request; balance_inr above is after

X-Balance-INR is always your credit balance at the start of the request, before its charge; balance_inr in the body is the balance after. Streaming responses have no body-level cost — the exact cost is settled and recorded as soon as the stream completes. Full history is available in your dashboard’s Analytics.

Recharging

Buy credits any time from the dashboard. Payments are processed by Razorpay and support UPI, RuPay, Visa/Mastercard, and net banking. Every ₹1 you pay buys 1 credit (₹500 → 500 credits) with nothing added at checkout, and every recharge is invoiced — so there’s nothing extra on individual API calls. Recharges are final except in specific cases (duplicate payment, a failed top-up that still debited you, or a verified platform billing error) — see our Refund Policy for those exceptions.
