Basic overview

The Hoyodecrimen REST API allows you to query crime data about Mexico City. You can even do fancy things like get the top 9 cuadrantes where homicide counts changed the most.

Since the API is based on REST principles and returns JSON data, it’s very easy to write applications that use it. You can use your browser to access any API URL, or pretty much any HTTP client in any programming language (yes, even something like STATA).

For example, https://hoyodecrimen.com/api/v1/crimes will return a list of all crimes in the database. https://hoyodecrimen.com/api/v1/cuadrantes will return a list of all the cuadrantes in the Federal District. Once you have a list of crimes and cuadrantes you can use https://hoyodecrimen.com/api/v1/cuadrantes/c-1.1.1/crimes/homicidio%20doloso/series to get a time series of the homicide rate in cuadrante C-1.1.1 (the API is case insensitive). Note that homicidio%20doloso can be changed to all to get all the crimes that occurred in that cuadrante.

Status

This is beta software and paths may break (but not much). If you notice an error, have any comments, or stuff you’d like added to the API raise an issue on GitHub or email me at diego@diegovalle.net. All data comes from freedom of information requests to the Mexico City government, sometimes I get data on crimes which happened in non-specified cuadrantes (NO ESPECIFICADO) and sometimes not, depending on how lucky I get when the FOIA request is answered.

Getting Started

All endpoints are GET requests that send back an object filled will the relevant data. You really want to use JSONP to access the API. Here is a basic example of how to handle JSONP requests using jQuery.

$.ajax({
    dataType: 'jsonp',
    url: 'https://hoyodecrimen.com/api/v1/cuadrantes/c-1.1.1/crimes/homicidio%20doloso/series',
    success: function(data) {
        // console.debug(data)
    }
});

Handling Errors

If there is a validation error with the request, or the cuadrante or crime queried does not exist, an error object will be passed back which contains a short description of what went wrong.

Example Error Response:

$.ajax({
    dataType: 'jsonp',
    // notice the invalid start_date
    url: 'https://hoyodecrimen.com/api/v1/cuadrantes/c-1.1.1/crimes/all/series?start_date=2014-99?end_date=2014-07',
    success: function(data) {
        // console.debug(data)
    },
    error: function(xhr, error) {
        // console.debug(xhr.responseText); // error description
        // console.debug(xhr.status); //should be 400
    }
});

Note

Population is given in persons/year and corresponds to that of the 2010 census.
