With regards to Accuweather... many people asked me about implementing their API into Meteotemplate. Very soon I learned it is not free, what surprised me however, is that they dont even give the prices on their website - just "contact us if interested". I did some googling and found the prices are absolutely ridiculous. Like hundreds per year for the cheapest plan which has about 25% of data otherwise available for free from other services like DarkSky, Yahoo or YrNo. And the plans that have equivalent data... we are talking about thousands of USD annually
