BlaBlaCar search API allows to search for carpool trips, just as the BlaBlaCar’s website does. 

### Easily search for trips!
The BlaBlaCar API provides functions for searching and retrieving carpool data. With the API, developers can implement a trip search that displays trips, distance, duration, recommended price, savings, and links. BlaBlaCar API returns JSON data and accepts Key as the authentication method. 

#### Get an API key
In order to access to BlaBlaCar's search API, you first need to ask for an API key [here](https://support.blablacar.com/hc/en-gb/requests/new?ticket_form_id=360000312100).

#### Keep posted
From time to time, we will send planned maintenances, status and important evolutions on this [awesome mailing list](http://eepurl.com/cHubeL). Feel free to register if you want to stay informed.

#### How NOT to use the API?
- As a realtime platform, seats availability may change very often and there might be new trips offered anytime. For this reason, you shouldn't cache the results you retrieve from the API, or for a very small time (10 min max). Also, caching may bypass the "locale" parameter which would result into not the best relevant experience for the user.
- Every query should be triggered by a real user input.
- There is no bulk query so you need to make 1 query for each user's request.
