Is the paper api endpoint working?

Alpaca Account Troubleshooting
1

I’ve tried following the docs and using curl, Python (with requests not the SDK) and Julia and get 404 when hitting some of the paper-api endpoints. I’m able to get my account information but not quote/market data.

I’d like to use Julia but am testing with Curl and python. Not sure what is going wrong.

Thanks in advance,

Julio

With a Curl example (using my own keys) I do:

curl -v -X GET
-H “APCA-API-KEY-ID: {YOUR_API_KEY_ID}”
-H “APCA-API-SECRET-KEY: {YOUR_API_SECRET_KEY}”
https://paper-api.alpaca.markets/v2/stocks/AAPL/bars\?timeframe=1Day\&start=2021-09-01T00:00:00Z

and get:

The Data API base URL is https://data.alpaca.markets/v2

Thanks. That seemed to work for the quick test I just did.

FWIW The docs say api.alpaca.markets and paper-api.alpaca.markets API v2 - Documentation | Alpaca

These URLs are for Trading API. For Data API both Paper and Live use the same URL .

Im using zipline and getting the error below…does this have anything to do with this thread?

raise HTTPError(http_error_msg, response=self)

requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://data.alpaca.markets/v1/bars/day?symbols=TSLA%2CAAPL%2CGOOG&limit=1000&end=2022-06-06T00%3A00%3A00%2B00%3A00

Again, the Alpaca Data API v1 is obsolete for months and you have to use the https://data.alpaca.markets/v2 as the base URL for your requests. The response format is also different of course.

Hi @Sony

I am not able to reproduce on my end can you share which endpoint you are referring to. could you also give us the payload please and would be great to check our document about environment market data here and you can easily access our Market Data APIs via Postman collections on Postman public workspace
