You Build AI Apps.We Handle the Rest.
The first unified AI API platform built for Bangladeshi developers. Access every major AI model. Pay in Taka.
The Struggle of Building AI in Bangladesh
Every Bangladeshi developer building with AI knows this pain...
"My Card Got Declined... Again"
OpenAI, Anthropic, Google — none of them accept Bangladeshi cards. You need a dual-currency card, a friend abroad, or expensive workarounds just to get started.
"Managing 5 Different API Keys"
ChatGPT for chat, Claude for analysis, Gemini for vision... Each provider has different docs, different billing, different rate limits. It's chaos.
"$20 Feels Like ৳5,000"
When you're a student in Dhaka or a freelancer in Chittagong, paying $20/month for each AI service adds up fast. It's not sustainable.
"No Local Support When Things Break"
When your API stops working at 2 AM before a deadline, good luck getting help from a US-based support team that's asleep.
"Why is it so hard to build AI products in Bangladesh?"
— Every developer we talked to
So We Built OneAPI
A single API that gives you access to every major AI model. Built for developers everywhere in Bangladesh.
Pay in Taka. No Card Hassle.
bKash, Nagad, Rocket, bank transfer — pay however you want. No international card needed. No currency conversion headaches. Just simple, local payments.
One API. Every Model.
ChatGPT, Claude, Gemini, DeepSeek, Llama, Mistral — all through one endpoint. Switch models by changing one parameter. No new SDKs, no new documentation to learn.
Support That Speaks Your Language
We understand your timezone, your challenges, and we're here when you need us — in Bangla or English.
All the models you need
Start in 3 Minutes
No complex setup. No waiting for approvals. Just code.
Sign Up & Get Your Key
Create an account, add credit via bKash/Nagad, and get your API key instantly.
Copy the Code
Use our OpenAI-compatible endpoint. If you've used ChatGPT's API before, you already know how.
Build Something Amazing
Switch between models, scale your app, and focus on what matters — your product.
