Quote Endpoint Sometimes Returns '0' for all Data #54

Closed LordA98 closed 4 years ago

LordA98 commented 4 years ago

Hi,

The API is really nice and the call limit is amazing.

However, I seem to be having an issue with some calls to the Quote endpoint.

As batch quotes are not supported, I iterate over an array that contains string values for company symbols and make an API call for each.

The array is similar to this: ['AAPL', 'TSLA', 'FB', 'NFLX', 'SNAP']

Sometimes a value of '0' is returned for each data element. I thought it may have been an application issue, but querying the API directly in the browser also returns the same response sometimes.

I understand there is a limit of 30 calls per second but I am only using 5. I thought it may have been due to API call weighting, but it isn't clear what the weight of a quote API call is?

(I have omitted my API key from the image).

Refreshing this would return data but implementing code functionality to handle the 0 cases isn't ideal.

I'd really appreciate any help!

Thanks, Alex

Hi,

This issue is due to a spike in usage today. Should be fixed now. Feel free to reopen the issue if it keeps happening tmr.

Finnhub Support,

Good evening:

I'm seeing this for several symbols. Here is an example:

$ curl "https://finnhub.io/api/v1/quote?symbol=AHL-C&token=$token"
{"c":0,"h":0,"l":0,"o":0,"pc":0,"t":0}

This is a transient error I take it, then? Does it clear on it's own or does it need to be reported?

Mine cleared on its own. It occasionally crops up once every now and then but doesn't re-occur for a while. No clear pattern. The only reason I could think of is that I was accidentally using the 60 call per/min limit and not realising.

However, I haven't used the API in a few weeks so can't speak for the error more recently.

I'm seeing this pretty consistently for symbols with non-alpha characters in them. I tried urlencoding the dash in AHL-C to no effect.

EDIT: This is unrelated to API limits for me. Despite multiple retries AGM-A is the only symbol with a dash I've been able to pull a quote for.
