Contribution Aggregates API

Search Methods

Search by Name

Search for entities--that is, politicians, individuals, or organizations--with the given name. Returns basic information about the the contributions to and from each entity, as well as an ID that can be used in other API methods to retrieve more information.

Note that name searches will by default return matches from all entity types. If you are searching for entities of a particular type, politicians, for example, we recommend that you use the type parameter to limit your search results.

End Point


The query string. Spaces should be URL-encoded or represented as +. There are no logic operators or grouping.
The entity type to search for. Can include "politician", "organization", "individual", or "industry".


            [{"name": "Nancy Pelosi for Congress",
              "type": "organization",
              "total_received": "0",

ID Lookup

Look up the entity ID based on an ID from a different data set. Currently we provide a mapping from the ID schemes used by Center for Reponsive Politics (CRP) and the National Institute for Money in State Politics (NIMSP), as well as a few other datasets. The result is a JSON object listing the TransparencyData IDs matching the given external ID.

End Point



The dataset and data type of the ID. Currently allowed values are:

namespace Description
urn:crp:individual A CRP ID for an individual contributor or lobbyist. Begins with U or C.
urn:crp:organization A CRP ID for an organization. Begins with D.
urn:crp:recipient A CRP ID for a politician. Begins with N.
urn:crp:industry CRP's 3-letter category order.
urn:crp:subindustry CRP's 5-letter category code.
urn:crp:subindustry CRP's 5-letter category code.
urn:nimsp:organization A NIMSP ID for an organization. Integer-valued.
urn:nimsp:recipient A NIMSP ID for a politician. Integer-valued.
urn:nimsp:subindustry NIMSP's 5-letter category code.
urn:sunlight:lobbyist_registration_tracker_url URL of Sunlight's lobbyist registration tracker page

More namespaces may be added in the future as other ID schemes are reconciled with the TransparencyData dataset.

The ID of the entity in the given namespace.
The ID of a member of congress in the Congressional Bioguide. Use of this parameter is mutually exclusive to the 'id' and 'namespace' parameters.
