Cloud Function API Call Quota exceded after invoking more than 16 times

[karanrk]

To be specific it hits the API calls hard limit for the project

Quota  | Description | Limit  | Can be increased | Scope
API calls (CALL) | Calls to the "call" API | 16 per 100 seconds | No | 2 per project

According to google cloud documentation, we can't even increase this quota. Why is serverless using test function invocation to invoke functions within google cloud.

I have a solution for this problem, but i need help in calling an API within serverless application, tried using request module seems to get ignored.
