*** HTTP QUERY INTERFACE ***

The HTTP query interface to the Biodiversity Heritage Library (BHL) API exposes methods for extracting data using HTTP GET requests.

AUTHENTICATION

To use the BHL API you must supply an API Key value with each request. To obtain a key, go to http://www.biodiversitylibrary.org/getapikey.aspx. The same key can be used for both the HTTP Query interface and the SOAP interface.

To include the key value with a request, append the argument &apikey=<key+value> to the method call. For example, http://www.biodiversitylibrary.org/api2/httpquery.ashx?op=<method>...&apikey=<key+value>

OUTPUT TYPES

Results can be returned in either XML or JSON format. To return XML, append &format=xml to the method call. To return JSON, append &format=json to the method call. If a format is not specified, XML is returned.

An example of returning XML is http://www.biodiversitylibrary.org/api2/httpquery.ashx?op=<method>...&apikey=<key+value>&format=xml

An example of returning JSON is http://www.biodiversitylibrary.org/api2/httpquery.ashx?op=<method>...&apikey=<key+value>&format=json

CALLBACKS

If you need to capture the results of a method call with a callback function, specific the name of the callback function by appending &callback=<function name> to the method call.

For example, http://www.biodiversitylibrary.org/api2/httpquery.ashx?op=<method>...&apikey=<key+value>&callback=<function name>

STATUS CODE

Each method response contains a status code that indicates the success or failure of the method call. This code is contained in the "Status" field of the response. The valid status codes are:

ok - the method executed successfully
error - an error occurred while executing the method; check the ErrorMessage field for details
unauthorized - the specified api key is invalid or does not have permission to execute the method
