We are designing an API for one of our products and would love to learn from the best. As a developer, what's the best (any why) Web based API you ever used?
I liked ones that I used and had Swagger documentation, that way you can easily make API calls in the API's documentation.
Take for example pipedrive: https://developers.pipedrive.com/v1
Parse. I like APIs you can copy/paste into javascript and build an MVP and worry about fail-proof server-side integration for production later.
Another vote for this one, felt like you were up and running within minutes. Used it with their iOS SDK.
Whatever web API I use I like it to be documented in automatic way so that is always up to date. Especially in first phase API changes, and I remember bad days spent in discovering the new version of some Facebook api before they get published..sort of MSDN black box hell
Another vote for stripe. I know of many junior web devs cutting their teeth on stripe. It's too easy.
