A really free API for weather.
Your mileage may vary, but I found this particular API to be too unstable for any applications that needed solid uptime. Reasonably easy to work with though…perfect for a personal project.
If you want more options from your weather API (and don’t mind possibly paying), check out http://www.wunderground.com/weather/api/ as an alternative.
Having used wunderground’s API extensively… It’s godawful. Barely documented, and frequently fails requests for hours at a time. On the upside, their search is pretty decent - I can throw zip codes, postal codes, IATA designators, city names etc. (OpenWeatherMap’s searching could use some improvement in this regard).
forecast.io was brought to my attention today, as a result of this post, and I’m liking it so far. Great documentation, higher limits, and comparable searchability. Plus their core product is very slick looking.
That’s a shame! I never got to play with it much, but I just assume (incorrectly!) that paid meant it was also going to be of a high quality =( forecast.io seems worth investigation!
You should check out https://developer.forecast.io API, their pricing is very reasonable
