Build a Dhan API trading bot with your AI coding agent.

How Dhan API access and login work

Dhan gives you three ways to get an access token. Generate one in the web app, call a TOTP method, or use an API key with a browser consent step. Each token lasts 24 hours from the moment it is made.

Scripted TOTP login is allowed for your own account, because Dhan documents it for API-only flows. Keep the PIN and TOTP seed in a secret store, never in the repository or chat. Platforms that serve other users apply to Dhan as partners.

Static IP for Dhan API algo trading

Since 1 April 2026, Indian brokers accept API orders only from a registered static IP. Dhan requires one to place, modify and cancel orders, super orders and forever orders; fetching orders needs none. You set primary and secondary IPs in the web app or through the API, as IPv4 or IPv6.

Each person needs a unique static IP, and after a change it cannot be edited for 7 days. Run the bot at home only if your provider gives that line a static IP, or rent a server. Backtests and paper trading send no orders, so they need no static IP. This is a summary, not legal advice.

Can you paper trade with Dhan?

A Dhan sandbox is reported, open without a Dhan account, with trading and data APIs shaped like the live ones. It has no streaming data, no real-time quotes and no realistic fills or slippage. Use it to test order flow and error paths, not strategy results.

For strategy results, Super Algo Kit uses its own paper trading, which sends no orders to Dhan. Paper first, live only when you say.

Dhan API limits and costs to plan for

These are Dhan's documented limits as the kit read them on 30 September 2026. The docs do not say whether order limits count per key, IP or account.

• Order APIs: 10 a second, 250 a minute, 1,000 an hour, 7,000 a day.
• At most 25 modifications per order.
• Data APIs: 5 a second and 100,000 a day. Quotes: 1 a second.
• Market feed: 5 connections per user, 5,000 instruments each.
• Trading APIs are free; data APIs carry extra charges shown on Dhan's platform.

What Super Algo Kit does with DhanHQ

The kit puts every call behind its own adapter, even though the official Python client is MIT-licensed. Your agent never holds your live keys or places live orders.

• Makes a fresh token each day and waits in a clear state if that fails.
• Redacts addresses in logs, because the TOTP call and feed address carry secrets.
• After a timeout, looks the order up by its client tag before any resend.
• Treats an order still in transit as undecided, never as a rejection.
• Reads the registered IP at start-up and blocks orders on a mismatch.
• Caps order messages at 5 to 8 a second, with a risk gate and kill switch.
