Getting started

Getting started

Install the calendar, then make one call to the hosted API.

# 1. the open-source calendar needs no account
pip install aion-indian-market-calendar

# 2. check whether NSE equity is trading today
from aion_indian_market_calendar import NSEEquityCalendar
from datetime import date

cal = NSEEquityCalendar()
print(cal.is_business_day(date.today()))

Call the hosted API

One endpoint: POST https://api.aionanalytics.in/v1/analyze. Send your key in the X-API-Key header and the headline in a JSON body as headline.

# cURL
curl -X POST "https://api.aionanalytics.in/v1/analyze" \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $AION_API_KEY" \
  -d '{"headline": "RBI hikes repo rate by 25 bps"}'

# Python
import os
import requests

response = requests.post(
    "https://api.aionanalytics.in/v1/analyze",
    headers={"X-API-Key": os.environ["AION_API_KEY"]},
    json={"headline": "RBI hikes repo rate by 25 bps"},
    timeout=30,
)
response.raise_for_status()
result = response.json()
print(result["confidence"], result["top_negative_sectors"])

Getting a key, and the referral code

Hosted API keys are issued with a plan. Indian Market Intelligence has a free plan, 10 requests per month with no card (a verified email and a passkey are required), and paid plans: Builder, ₹999 a month, or Professional, ₹4,999 a month. Choose one at /subscribe/indian-market-intelligence or see /apis.

Referral code. Registration at /access/register is a separate path. It requires a referral code and is for approved dashboard and local-agent testers; it is not how hosted API keys are issued. Referral codes are not published. To ask about tester access, write to [email protected].

Request and response fields, quotas and error codes are in api-reference.txt.
