Drishti SDK (Python)

Official Python SDK for the Manasija Drishti API (/v1).

This SDK provides:

• A synchronous HTTP client with named-argument endpoint helpers
• A low-level request interface for advanced/custom usage
• A WebSocket client for real-time streams (/v1/ws)
• Configurable retry/backoff for transient HTTP failures

Requirements

• Python 3.10+
• A valid Drishti API key

Installation

pip install drishti-sdk

Quick Start

from drishti_sdk import DrishtiClient

with DrishtiClient(api_key="YOUR_API_KEY") as client:
    news = client.get_news(
        symbols=["RELIANCE", "TCS"],
        limit=10,
    )
    print(len(news["data"]))

All requests automatically include X-API-Key using the provided api_key.

Retry Configuration

Retries are configurable globally on the client and per request.

from drishti_sdk import DrishtiClient

with DrishtiClient(
    api_key="YOUR_API_KEY",
    retry_max_retries=3,
    retry_initial_delay=0.25,
    retry_max_delay=4.0,
    retry_multiplier=2.0,
    retry_on_statuses=(408, 429, 500, 502, 503, 504),
) as client:
    # Per-request override
    news = client.request(
        "GET",
        "/v1/news",
        params={"limit": 10},
        retry_max_retries=1,
    )

HTTP Usage

from drishti_sdk import DrishtiClient

with DrishtiClient(api_key="YOUR_API_KEY") as client:
    announcements = client.get_announcements(
        symbols=["RELIANCE"],
        categories=["Corporate Action"],
        important=True,
        detailed=True,
        limit=20,
    )

    earnings = client.get_earnings_detail(
        symbol="MEDIASSIST",
        quarter="q4_26",
        detailed=True,
    )

    earnings_rows = client.get_earnings(
        ids=["67c2f8a1b2c3d4e5f6a7b8d0"],
        limit=5,
    )

    transcript = client.get_concalls_transcript(
        symbol="TCS",
        quarter="q4_26",
    )

    alerts = client.get_alerts(
        symbols=["INFY"],
        important=True,
        limit=25,
    )

Error Handling

from drishti_sdk import DrishtiApiError, DrishtiClient

try:
    with DrishtiClient(api_key="YOUR_API_KEY") as client:
        client.get_account()
except DrishtiApiError as exc:
    print(exc.status_code)
    print(exc.body)
    raise

WebSocket Usage (/v1/ws)

Event listeners

import asyncio
from drishti_sdk import DrishtiClient


async def main() -> None:
    client = DrishtiClient(api_key="YOUR_API_KEY")
    async with client.websocket(
        reconnect_initial_delay=1.0,
        reconnect_max_delay=30.0,
        on_reconnect_attempt=lambda attempt, delay, reason: print(attempt, delay, reason),
        on_data=lambda event: print(event.data) if event.kind == "data" else None,
        on_announcements=lambda announcement: print("announcement", announcement),
        on_alerts=lambda alert: print("alert", alert),
    ) as ws:
        await ws.subscribe("alerts", symbols=["RELIANCE"])
        await asyncio.Event().wait()  # listeners run in the background; Ctrl+C to stop


asyncio.run(main())

Async iterator style

async with client.websocket() as ws:
    await ws.subscribe("announcements", symbols=["RELIANCE"], detailed=False)
    async for event in ws.events():
        if event.kind == "subscribed":
            print("ready", event.product, event.tier)
        elif event.kind == "data":
            print(event.channel, event.data)

Register listeners after connect:

def on_announcement(announcement: dict[str, object]) -> None:
    print("announcement", announcement)

ws.on_announcements(on_announcement)
ws.off("announcements", on_announcement)

WebSocket Reference

The WebSocket session is created from the HTTP client, so it inherits the same api_key and base_url settings. The session connects to /v1/ws and sends X-API-Key on connect.

Supported subscription products:

• news
• announcements
• earnings
• concalls
• alerts

Useful session options:

• reconnect_initial_delay
• reconnect_max_delay
• reconnect_backoff_multiplier
• reconnect_jitter_ratio
• reconnect_warn_after_attempts
• ping_interval
• ping_timeout
• open_timeout
• close_timeout
• max_queue
• on_subscribed
• on_data
• on_news
• on_announcements
• on_earnings
• on_concalls
• on_alerts
• on_error
• on_message
• on_open
• on_close
• on_reconnect_attempt
• on_reconnect_warning

The session connects automatically on the first async call (subscribe, events, or entering an async with block) and keeps retrying in the background after disconnects.

Subscription messages accept either SubscribeOptions(...) or the product name as a string. Symbols are normalized to uppercase and de-duplicated before the message is sent. Subscriptions are replayed after every reconnect.

Event shapes:

• subscribed: acknowledgement with product, tier, full_feed, symbols, and detailed
• data: payload event with channel and data
• error: error event with message and optional code
• raw: unclassified JSON payload

Direct exports available from drishti_sdk:

• DRISHTI_WS_PRODUCTS
• SubscribeOptions
• DrishtiWebSocketSession
• DrishtiWebSocketClientSessionOptions
• DataEvent
• ErrorEvent
• RawEvent
• SubscribedEvent
• WebSocketEvent
• build_websocket_url
• parse_websocket_message
• stream_product

Batch Jobs

from drishti_sdk import DrishtiClient

with DrishtiClient(api_key="YOUR_API_KEY") as client:
    with open("batch.jsonl", "rb") as f:
        file_bytes = f.read()

    job = client.post_batch_jobs_file(
        file_name="batch.jsonl",
        file_bytes=file_bytes,
        display_name="Quarterly run",
    )

    status = client.get_batch_jobs_job_id(job_id=job["id"])

Wait until completion:

final_job = client.wait_for_batch_job_completion(
    job_id=job["id"],
    poll_interval=2.0,
    timeout=300.0,
)

Submit and wait in one call:

final_job = client.submit_batch_job_and_wait(
    file_name="batch.jsonl",
    file_bytes=file_bytes,
    display_name="Quarterly run",
    poll_interval=2.0,
    timeout=300.0,
)
