Best Way to Use AI APIs from India in 2026: INR Gateway vs Global Gateway vs Going Direct
Indian developers have three practical ways to pay for AI model APIs in 2026: go direct to each provider (OpenAI, Anthropic, Google), use a global AI gateway that bills in US dollars, or use an INR-native gateway like Velona. The short answer: pick Velona if you want to pay in rupees with UPI or start small, pick a global gateway if you have a card that works abroad and buy credits in bigger chunks, and go direct if you only need one provider and your card is accepted.
This comparison covers how each option takes payment, what you really pay per ₹100 of model usage after fees and forex, model coverage, and how to switch between them without rewriting code.
Comparison at a glance
| Velona (INR gateway) | Global gateway | Direct (OpenAI, Anthropic, Google) | |
|---|---|---|---|
| Billing currency | Indian rupees | US dollars | US dollars |
| Payment methods | UPI, RuPay, domestic debit and credit cards, net banking | International cards, sometimes crypto or wallets | International cards |
| Minimum top-up | ₹10 | Usually a few dollars, often with a minimum fee | Varies by provider |
| Fee on top of model price | 7% platform fee plus 0.5% forex buffer, already inside the ₹ price | Typically around 5 to 5.5% on each credit purchase, often with a minimum fee | None |
| Bank forex markup | None, it is a rupee payment | Whatever your card charges | Whatever your card charges |
| Models behind one key | 300+ | Hundreds | One provider's models only |
| OpenAI-compatible API | Yes | Usually yes | OpenAI yes, others use their own SDKs |
| Usage dashboard in ₹ | Yes, per request | No, USD | No, USD |
| Based in | Kolkata, India | Usually outside India | United States |
The real cost: what you pay for ₹100 of model usage
Headline fees hide the full picture, because paying a dollar merchant with an Indian card usually adds a foreign currency markup. Many Indian credit cards charge around 3.5% on foreign transactions, plus 18% GST on that markup, which works out to roughly 4.1%. Some premium and forex cards charge nothing. Here is the all-in cost of ₹100 worth of model usage at list price, using a typical global gateway fee of 5.5% with a $0.80 minimum:
| Option | Card with ~3.5% forex markup | Card with zero forex markup |
|---|---|---|
| Velona (UPI or any top-up size) | ₹107.54 | ₹107.54 |
| Global gateway, $10 top-up | ₹112.46 | ₹108.00 |
| Global gateway, $100 top-up | ₹109.86 | ₹105.50 |
| Direct to provider | ₹104.13 | ₹100.00 |
How the numbers work: Velona's price is the provider's list price x 1.005 x 1.07, paid in rupees, so no bank markup applies. A 5.5% fee with a $0.80 minimum becomes 8% on a $10 purchase. Going direct has no platform fee, only your bank's forex charge. These figures leave out tax on the service itself, which can apply to any of the options.
What this means: if you top up small amounts or pay with a normal Indian card, Velona costs less than a dollar-billed gateway. If you buy $100 or more at a time with a zero-markup card, a global gateway comes out around 2% cheaper. Going direct is cheapest of all, as long as the provider accepts your card and you only need that one provider.
Payments: the deciding factor for most Indian developers
For most people in India, price differences of a few percent matter less than whether the payment goes through at all. OpenAI's developer forum has years of threads from Indian users whose Visa, Mastercard and debit cards were declined, usually blamed on RBI e-mandate rules for recurring charges, 3D Secure failures or international usage being switched off. Students and first-time builders often don't have an international card at all.
Velona takes payment in rupees through Razorpay, so it works with UPI apps like Google Pay, PhonePe and Paytm, RuPay cards and net banking. Your bank statement shows a rupee transaction with no surprise forex line weeks later.
Model coverage
- Direct gives you one provider per account and one bill per provider. Using GPT, Claude and Gemini together means three accounts and three cards on file.
- Global gateways usually have large catalogues, including niche and experimental models.
- Velona has 300+ models, including GPT-5.1, Claude Sonnet 5 and Opus 4.8, Gemini 3.1 Pro, DeepSeek V4, Grok 4.5, Kimi K2.6, Qwen3 and Llama 4, all priced in rupees on the model catalogue.
For almost every Indian developer project, the models that matter are available on Velona.
Switching costs: the code is almost identical
Velona works with the official OpenAI SDK. Moving an existing project over is a change to two lines, the API key and the base URL:
from openai import OpenAI
client = OpenAI(
api_key="YOUR_VELONA_KEY",
base_url="https://velona.in/v1",
)
response = client.chat.completions.create(
model="anthropic/claude-sonnet-5",
messages=[{"role": "user", "content": "Explain what an AI API gateway does in three sentences."}],
max_tokens=200,
)
print(response.choices[0].message.content)Model IDs use the common provider/model format, such as openai/gpt-5-mini or google/gemini-3-flash, so most existing gateway code carries over as it is. There is no lock-in. You can start on Velona with UPI and move later if your needs change.
What else each option gives you
Velona
- Per-key spending limits, so a student project or test script can't drain your wallet
- A usage dashboard that shows the rupee cost of every request
- A free chat to try models before you top up
- 49 free developer tools and an AI benchmark page to compare models by quality and price
- Support during Indian working hours from a team based in Kolkata
Global gateways
- Large model catalogues, often with some free models under rate limits
- Bring-your-own-key options for teams that already hold provider accounts
Direct providers
- Lowest list price and first access to provider-specific features
- Enterprise contracts, higher rate limits and direct support at scale
Which one should you choose?
- Choose Velona if you are a student, an indie builder or a small team in India, you want to pay with UPI, you want to start with ₹10, or your card keeps getting declined abroad.
- Choose a global gateway if you have a card with low or zero forex markup, buy credits in larger amounts, and need very niche models.
- Go direct if you use only one provider at high volume and your card or company billing already works with them.
Plenty of developers mix them: Velona for day-to-day projects paid by UPI, and a direct account once a single model's spend grows large enough to negotiate.
Frequently asked questions
What is the best AI API for developers in India?
For most Indian developers, students and small teams, an INR-native gateway like Velona is the easiest choice: 300+ models behind one OpenAI-compatible key, priced in rupees, with top-ups by UPI from ₹10. Large teams using a single provider at high volume may save a little by going direct.
Is there an AI API gateway that accepts UPI?
Yes. Velona is an India-based AI API gateway that accepts UPI, RuPay, domestic debit and credit cards and net banking, and bills every model in rupees.
Do global AI gateways accept UPI or rupee payments?
Most bill in US dollars and accept international cards, and some accept crypto or digital wallets. UPI and RuPay are rarely supported, which is why INR-native gateways exist.
Is an INR gateway more expensive than a dollar gateway?
For small top-ups and most Indian cards, no. Velona's all-in cost is about ₹107.54 per ₹100 of usage, against roughly ₹108 to ₹112 on a typical dollar gateway after its fee and normal bank forex charges. For $100 or larger purchases on a zero-markup card, a dollar gateway can be about 2% cheaper.
Can I use Claude, GPT and Gemini with one API key in India?
Yes. On Velona one key works for GPT, Claude, Gemini, DeepSeek, Grok, Llama and 300+ other models, all billed in rupees.
Who runs Velona?
Velona is built and operated in Kolkata, West Bengal, by Knowledge Research Evolution Automation LLP, and is designed specifically for Indian developers, students and indie builders.
