# CrisisNET



#### A firehose of worldwide crisis data.



[CrisisNET](http://crisis.net) gives app developers, data-journalists and other makers fast, easy access to critical government, business, humanitarian, and crowdsourced data. Our API reduces the time it takes to access and use crisis-relevant data from hours (even days) to minutes.



## Getting Started



Register for an API key using [our developer portal](http://devapi.crisis.net/). (Note: we're currently in private beta, so the portal is a work in progress.)



## Getting Data



Now that you have an API key, CrisisNET data is yours for the taking. You'll find more detailed instructions below, but a basic request looks like this:



    $.ajax({

      url: 'http://api.crisis.net/item?apiKey='+ YOUR_TOKEN_HERE+'location=36.821946,-1.292066',

      dataType: "json",

      success: function (data) {

        console.log(data);

      }

    });



The above request is in JavaScript (using jQuery), so you'd run that from a web browser. However, because CrisisNET is a REST API, you can access it using any language that can make HTTP requests (Python, PHP, Java, etc etc). Here's the same example in Python, just for fun:



    import requests



    url = 'http://devapi.crisis.net/item&location=36.821946,-1.292066'

    headers = {'Authorization': 'Bearer ' + YOUR_TOKEN_HERE}



    r = requests.get(url, headers=headers)



## Filtering Data



As you probably noticed above, both requests are to the `/item` endpoint. In CrisisNET, an `Item` resource is very general -- basically a thing that exists in a place (usually at a specific time). This might be a tweet or Facebook status, a news item, NGO survey response, entry from a municipal dataset, etc etc. In this way we give you the power to shape your data stream in whatever way makes the most sense for your use case.



### List 'O Filters



Name | Description | Type/Example

--- | --- | --- 

*before* | Only retrieve records before this date/time. | timestamp in ISO 8601 format: `YYYY-MM-DDTHH:MM:SSZ` eg `before=2014-02-10T10:50:42.389Z`

*after* | Only retrieve records after this date/time. | timestamp like `before`

*tags* | Get records matching *all* of these tags. | comma-separated list of strings eg `tags=health,injury`

*text* | Full-text search on title + text properties. | url-formatted string eg `text=needle+in+haystack`

*location* | Coordinates around which to search. | coordinate pair of longitude, latitude eg `location=36.821946,-1.292066`

*radius* | Get records within x meters of `location`. Defaults to 10. | number in meters, eg `radius=10`

*limit* | Limits the number of records returned. Defaults to 25. | number, eg `limit=100`

*offset* | Useful in conjunction with `limit` for paginatated through results. | number, eg `offset=25`

*sources* | Limit results based on where they originated (outside of CrisisNET) | comma-separated list of strings eg `sources=twitter,facebook`

*licenses* | Limit to records with specific licenses. Useful if you're looking for data to use commercially, for example. | comma-separated list of strings, eg `licenses=commercial,odbl`

*orderBy* | Property used to order result set. Deafults to `publishedAt` | any valid property name, eg `orderBy=title`
