How to Use the API (Python and R)

Dear User,

Thank you for your query. What language are you using to pull the data? I would advise that you search "IMF API [data language] documentation" to find information on how to set up your query.

Additionally, please see here for the documentation on how to set up an API query using Json Restful:

To give you some general ideas of what it might look like for Python and R:

If you are using Python, the following is a good resource to use when setting up your query: 

In general, for setting up your query, the root of the URL that you want to retrieve data from is:

Following that root, you will need to add on additional details about what data you would like:

  • Data type: "CompactData" to retrieve data, "DataStructure" to retrieve series information, or "GenericMetadata" to get metadata. 
  • Database you would like to query: For example, International Financial Statistics ("IFS"), Balance of Payments ("BOP"), etc. 
  • Frequency: Annual ("A"), Quarterly ("Q"), Monthly ("M")
  • Specific Indicator interested in: For CPI this is " PCPI_IX"
So, if you want to query the IFS database for monthly CPI data for 2000-2001, you would want to use the URL: 

Alternatively, if you are using R, you can install the "imfr" package. The syntax for a data pull using this package generally looks like:

imf_data(database_id = , indicator = , country = , freq = , start = , end = )

You can find the documentation for the R imfr package here:

We hope you find this information useful. Should you have any further questions please feel free to contact us.
