Anatomy of a response

Responses for non-count queries are divided into two sections, meta and results.

Meta

For non-count queries, the meta section includes a disclaimer, a link to the openFDA data license, and information about the results that follow.

  • meta.disclaimer
    string

    Important details notes about openFDA data and limitations of the dataset.

  • meta.license
    string

    Link to a web page with license terms that govern data within openFDA.

  • meta.last_updated
    string

    The last date when this openFDA endpoint was updated. Note that this does not correspond to the most recent record for the endpoint or dataset. Rather, it is the last time the openFDA API was itself updated.

  • meta.results.skip
    number

    Offset (page) of results, defined by the skip query parameter.

  • meta.results.limit
    number

    Number of records in this return, defined by the limit query parameter. If there is no limit parameter, the API returns one result.

  • meta.results.total
    number

    Total number of records matching the search criteria.

Results

For non-count queries, the results section is an array of matching records.
