These are the slides of our talk and demo at the PAPIs.io conference on Predictive APIs and Apps in Barcelona, November 17/18. In the demo we showed integration of various Web APIs: Bicing, Google Maps, and BigML. We customised API requests and responses exactly to our needs. That's the power of APItools.com A video of the live demo will be added soon. In the meantime you can find screenshots a the end of the slide deck.
