Hi! I have a question.
There is a date value in input, but historical weather data isn't free in openweathermap api.
Do I have to buy this to solve this issuse?

Hi @Sunghee2,

Very sorry for the late reply. That's a good point, let me ping our engineer @Amxx to give it a look!

Also, could you please apply on Gitcoin to work on this issue? So you can be eligible for the 500RLC bounty. Thanks!

[revcozmo]

Hi@sulliwne,

Yes, I am still working on this bounty.
I should be posting for your review Monday/Tuesday at the latest.

Thanks for your note.
Please standby.

[sulliwane]

@revcozmo cool.

@Sunghee2 I just had a look, if you can't find any alternative to openweathermap API for historical data (you may give https://darksky.net/dev/docs a try), then you can just do "live weather condition". Anytime there is a call, it retrieves the current conditions.

[Sunghee2]

@sulliwane Thank you! I'll try the API.
