Invalid openalgo apikey

JSON Format

{
    "status": "error",
    "message": "Invalid openalgo apikey"

Rate Limiting

The API is rate-limited to 10 requests per second by default. This can be configured using the API_RATE_LIMIT environment variable.

Date Range Restrictions

To prevent large queries that could hit broker rate limits, the API automatically restricts date ranges:

• Daily/Weekly/Monthly intervals (D, W, M): Maximum 10 years from end date

• Intraday intervals (1m, 5m, 1h, etc.): Maximum 30 days from end date

If a request exceeds these limits, the start date will be automatically adjusted. For example:

• Original request: http://127.0.0.1:5000/api/v1/ticker/NSE:ICICIBANK?apikey=your_api_key_here&interval=1m&from=2000-06-01&to=2025-07-04&format=txt

• Adjusted to: from=2025-06-04&to=2025-07-04&interval=1m (30 days for 1-minute data)

Notes

1. All timestamps in the responses are in Indian Standard Time (IST)

2. Volume is always returned as an integer

3. If no symbol is provided, defaults to "NSE:RELIANCE"

4. If no exchange is specified in the symbol, defaults to "NSE"

5. The API supports both formats:

   • NSE:RELIANCE (preferred)

   • RELIANCE (defaults to NSE)
