+14 moreWHY ONE API
Every broker API is different. Yours doesn’t have to be.
Integrating broker APIs yourself
- A different login, order format and error codes for every broker
- A separate order-update stream for each account
- Positions merged by hand across accounts
- Code breaks when a broker changes its packets
- Changing brokers means a new integration
With the Quantsapp Orders API
- One login, one order format, one set of responses
- Every update from every account on one WebSocket
- Combined positions and order status in one call
- Broker changes handled by Quantsapp
- Change brokers by changing one value
| Fyers API directly | Through Quantsapp | |
|---|---|---|
| Brokers covered | Fyers only | Fyers + 19 other brokers |
| Several accounts | Each account separately | All accounts in one request |
| Order updates | A stream per account | One WebSocket for every account |
| If the broker changes its API | You update your code | Quantsapp absorbs the change |
| Changing brokers later | Write a new integration | Change one value |
WHAT YOU GET
Built for algo traders and multi-account order management
One API, every broker
The same requests and responses for all 20 brokers. No broker SDKs, no broker-specific order formats.
REST and WebSocket
Every call over REST (HTTP/1.1, 2 and 3) or over a WebSocket - pick what suits your latency and stack.
One socket for every update
Order updates from all your accounts, at every broker, arrive on a single WebSocket, tagged with the account.
Many accounts, many brokers
Several accounts with the same broker - yours and your family’s - and accounts across brokers, side by side.
Place once, everywhere
One place-order request goes to several accounts at once, with its own lot multiplier for each.
Combined positions
Get positions account by account or combined, and order status for all accounts, without stitching broker responses.
Multi-leg with margin benefit
Send a whole strategy in one request; buy legs can go first so the hedge margin applies to the sell legs.
Broker changes? Not your problem
When a broker changes its packets or endpoints, Quantsapp absorbs it. Your code keeps working.
Switch brokers, keep your code
The broker is one value in the account id. Move brokers and the rest of your integration stays as it is.
A FEW LINES
One order, two brokers, one stream
Log in with your API key, place a two-leg spread in your Fyers account and a second account with different lot multipliers, and receive every order update on one callback.

ONE WEBSOCKET
Every order update, from every account, in one place
Fills, partial fills, rejections and cancellations from all your accounts - at every broker - stream on a single socket, each tagged with its broker account. No per-broker sockets to keep alive, no polling.
Orders placed through the API also show in the Quantsapp app, next to everything else.

Who it’s for

Family and multiple accounts
Place the same trade in all your accounts with one request, and see their orders and positions together.
Traders with more than one broker
Keep one integration while you trade with several brokers - or move between them.

Frequently asked questions
Is this the official Fyers API?
No. Fyers’s own API is Fyers API. Quantsapp connects to your Fyers account through Fyers’s official API and gives you one Orders API on top - the same code for Fyers and 19 other brokers. Orders go to your own Fyers account. Fyers is a trademark of its owner.
Why use Quantsapp instead of Fyers API directly?
If you only ever trade one Fyers account, the broker’s API may be enough. Quantsapp helps when you have several accounts or brokers, want one order-update stream for all of them, combined positions, or code that keeps working if Fyers changes its API or you change brokers.
How do I connect my Fyers account?
In Quantsapp, go to Trade → Brokers and connect Fyers (there is a guided video for each broker). Then create your API key and secret on the Orders API keys page in Quantsapp and log in to the API with them.
Do I need a static IP?
Yes, to place orders. SEBI rules require orders sent through an API to come from a static IP. Quantsapp’s shared static IP costs ₹250/month + GST per broker (a dedicated IP is ₹750/month + GST), or you can use your own. Reading orders and positions needs none.
What if my broker changes its API?
Quantsapp handles it. Your code talks to one Quantsapp format, so when a broker changes its packets or endpoints, the change is absorbed on Quantsapp’s side and your code keeps working.
Can I switch brokers without rewriting my code?
Yes. The broker is just part of the account id ("broker,client_id") in your requests. Connect the new broker, change that value, and the rest of your code stays the same.
How much does the Orders API cost?
₹20 per successful order placed through the API, or unlimited orders for ₹1,499/month on the yearly plan (₹2,999 on the monthly plan). Placing orders also needs a static IP (from ₹250/month + GST).
Which markets does it cover?
NSE F&O (futures and options on NSE) for now.
Is there a Python SDK?
Yes - pip install quantsapp. It is open source on GitHub and covers login, orders, positions and the live order-update stream. The REST and WebSocket docs also include JavaScript examples.
