Recently I had a hackathon challenge to work on realtime stock markect data end points.After the hours of research from the various stock market end-point-apis , I had short listed a few.I thought that might be enough to complete my project.

1. IEX , Pros: A real boon to stock market app developers because of the free unlimited api calls without any limitation. Cons: No realtime data , only with 15 min delay

2. AlphaVantage, Pros: A site for pro developers with near realtime data/live stock data but comes with api key mess and limitation on requests/min made

After a few days of walkthrough, I found my self on the fence because I have to make an auto complete search field like google search box for stock name/symbol searches.

the main catch here is Symbol Search AutoComplete functionality already found in AlphaVantage, that too 5 API calls/min and 500 api calls/day.Imagine your end user typing keyword of length about 6 char in a minute then you will run out of APIs.

Then I had an idea of mixing the both worlds, no API key mess from IEX and high end functionality from AlphaVantage. At first I googled if any already existed but found none while yahoo fiance api was widely used for keyword search,sadly it's deprecated. I had no other choice to stick to AlphaVintage which costs around $30/month,30 api/min.

Thus I ended up making my own keyword filtering on ~8000 stock symbols downloaded data.I thought it could be great if I host in cloud so that other devs can also use it.

Demo : https://tickersearch.surge.sh/

https://ticker-2e1ica8b9.now.sh//keyword/[KEYWORD_SEARCH] eg : https://ticker-2e1ica8b9.now.sh/keyword/googl

   [
    {"symbol":"GOOG","name":"Alphabet Inc."},
    {"symbol":"GOOGL","name":"Alphabet Inc."}
    ],
 "message":""
}

you can make request like this format below <Base_url>/keyword/[KEYWORD_SEARCH]/limit/[NUMBER]

eg : https://ticker-2e1ica8b9.now.sh/keyword/goog/limit/1

{"results":[{"symbol":"GOOG","name":"Alphabet Inc."}],"message":""}

you can make request like this format below <Base_url>/add/[symbol]/[name]

eg : https://ticker-2e1ica8b9.now.sh/add/META/thenewfacebookInc

you can make request like this format below <Base_url>/delete/[symbol]

eg : https://ticker-2e1ica8b9.now.sh/delete/META
