Indian Broker API Landscape¶
Reviewed first-party API catalog, integration surface, static-IP concerns and selection checklist.
Part 20 of 37 in the ServLoci algo/options trading notebook series — full index in notebooks/README.md.
Setup¶
# Get your dedicated static IPv6 + SOCKS5 credentials free:
# https://comm.servloci.in/register (or /auth/google?free=1 for an instant trial)
# Your api_key / api_secret pair shows up in the portal after signup:
# https://comm.servloci.in/user
!pip install -q "requests[socks]"
!curl -sL https://comm.servloci.in/sdk/servloci.py -o servloci.py
import os
from servloci import ServLoci
SERVLOCI_API_KEY = os.environ.get("SERVLOCI_API_KEY", "dhan:1000000001") # broker:client_id
SERVLOCI_API_SECRET = os.environ.get("SERVLOCI_API_SECRET", "") # from the portal — leave blank to run this notebook in demo mode
sl = None
if SERVLOCI_API_SECRET:
sl = ServLoci(api_key=SERVLOCI_API_KEY, api_secret=SERVLOCI_API_SECRET)
print("ServLoci configured:", sl.host, sl.port)
else:
print("SERVLOCI_API_SECRET not set — running in demo mode (no live proxy calls).")
Scope and how to read the list¶
This is a reviewed catalog of Indian retail brokers with public, first-party API documentation, checked 12 August 2026. It is not a claim that every SEBI-registered broker exposes a retail API. “ServLoci route” means a maintained broker allowlist exists today; “adapter” means the same OHLCV/indicator pattern works, but the broker origin still needs explicit ServLoci support before order traffic can be proxied.
Broker plans, rate limits, authentication and static-IP rules change. Recheck the linked official source before production use. Never send broker passwords, PINs, TOTP seeds or access tokens to ServLoci.

“Free API” can still exclude exchange-licensed real-time data, historical depth, account charges, brokerage, cloud egress or an external static IPv4. Compare the exact endpoint and plan you need—not the headline price.
Selection checklist¶
- Confirm the instruments and exchange segments you trade.
- Confirm candle intervals, history depth, corporate-action handling and live-feed entitlement.
- Check documented order limits, reconnect behavior, idempotency support, sandbox/paper support and postbacks.
- Verify current static-IP and OAuth/2FA policy. From 1 April 2026, Indian retail-algo implementation rules materially affect client-direct API order traffic.
- Test rejection, timeout, partial-fill and duplicate-order recovery before measuring latency.
- Keep analysis/data reads direct. Route only the broker calls that must originate from the approved static address.
Start with a read-only profile or funds endpoint, then paper/dry-run, then the smallest permitted live order. An API feature table is not a reliability ranking or a recommendation to trade.
