解决方案：

Add "phpdocumentor/reflection": "3.x@dev" under "require": { } in composer.json and run a composer update

"require": {

    "php": ">=5.5.9",
    "laravel/framework": "5.2.*",
    "phpdocumentor/reflection": "3.x@dev"
},

$ composer update
$ composer require dingo/api:1.0.x@dev

after successful command this will add "dingo/api": "1.0.x@dev" under require.

"require": {

    "php": ">=5.5.9",
    "laravel/framework": "5.2.*",
    "phpdocumentor/reflection": "3.x@dev",
    "dingo/api": "1.0.x@dev"
}
