@rudra This issue is resolved now, thanks to smart api team.

The OpenAPIScripMaster.json file is currently failing to download completely. Both the .angelbroking.com and .angelone.in endpoints return HTTP 200, but the download repeatedly stops midway due to read timeouts.

The file size is approximately 36.3 MB. The issue has been reproduced using an isolated Python script, while downloads from other providers are completing successfully. This suggests a possible issue with the Scrip Master delivery service or its network path.

Is this issue being experienced by other SmartAPI users as well? Could the SmartAPI team please investigate and confirm whether any service-side issues are affecting Scrip Master downloads?

Yes, it was an issue from their backend but as of now i am completely able to to download the scrip data.

i think the issue is now resolved from their end but it may take some time to reflect for some users.

i suggest to try again after 30 to 45 minutes.

Hi Team,

Just an update on this issue.

The OpenAPIScripMaster.json endpoint is now working normally again.

The file is downloading successfully without any interruption, and our production trading system is able to initialize and run as expected.

It appears the issue has been resolved on the server side.

Thank you to the SmartAPI team for restoring the service. We appreciate the quick resolution.

Regards,

Hi Team,

We are facing a critical issue with the latest OpenAPIScripMaster.json endpoint:

https://margincalculator.angelbroking.com/OpenAPI_File/files/OpenAPIScripMaster.json

This endpoint was working perfectly until yesterday. After today's Script Master update, every download attempt fails.

The server responds with HTTP 200 OK and advertises a Content-Length of 36,952,921 bytes, but the connection is terminated before the complete file is delivered.

We have reproduced the same issue using:

Python (requests)
Python streaming download
curl (HTTP/1.1 & HTTP/2)
Google Chrome
IPv4 & IPv6

Errors observed include:

IncompleteRead
ChunkedEncodingError
curl: HTTP/2 stream was not closed cleanly
curl: end of response with bytes missing

To rule out local issues, we also verified our internet connection by downloading large files from other HTTPS servers successfully at normal speed.

No changes have been made to our code or infrastructure. Yesterday's Script Master (~19 MB) downloaded successfully, but today's updated Script Master (~37 MB) consistently fails before completion.

This is currently blocking our production trading system, as the Script Master is required before initialization.

Could the SmartAPI team please check whether there is any issue with the latest Script Master file or the server/CDN serving this endpoint? Is anyone else experiencing the same issue today?

Thank you.
