Mentions

The Mentions endpoint gives you access to all of the individual mentions of the research outputs from your search.

The easiest way to programmatically access this data is by build a search within the Altmetric Explorer and exporting the results to the API. For more information see Using the Altmetric Explorer to create signed API requests.

Note

This endpoint can return a large number of results, and so it is paginated. Please refer to the Pagination section of the documentation to see how this works.

Important

This is the only endpoint that returns individual X (Twitter) post IDs, so it is subject to a limit on how many your organization can retrieve — see X post ID limit for the policy. Track your usage with the X-TweetIDRateLimit-Limit and X-TweetIDRateLimit-Remaining response headers; once the limit is reached, requests return a tweet_id_rate_limit_exceeded error.

Request

GET /explorer/api/research_outputs/mentions

GET /explorer/api/research_outputs/mentions?digest={digest}&key={key}&filter[{key}]={value}...&filter[{key}][]={value}

Basic GET request to get mention data.

Example request:

GET /explorer/api/research_outputs/mentions?key=YOUR_API_KEY&digest=YOUR_DIGEST HTTP/1.1
Host: www.altmetric.com

Query parameters:

Parameter Required Accepts Description
digest Yes A valid digest See Authentication
key Yes A valid key See Authentication
include No journal profile research-output journal shows information about the relevant journal, like ISSNs. profile shows information about the author of the mention. research-output shows information about the research output that has been mentioned. If omitted all types will be included.
filter[sentiment][] No A sentiment score from -3 to 3. Return only mentions carrying these sentiment scores. See Sentiment scores below. Sentiment is computed for X and Bluesky mentions only.
filter[highlights] No true Return only the mentions the Explorer treats as highlights, the same subset shown on its Highlights tab. Any other value is ignored.
filter[mention_types][] No A mention type, for example: msm, tweet, bluesky, rdt. Return only mentions of these types. See Mention types for the list. A type this endpoint holds no mentions for returns an empty result rather than an error, so check the spelling before reading anything into it.
filter[mention_sources][] No type:{mention type}, or the id of a mention source. Return only mentions from these sources. type:msm is equivalent to filter[mention_types][]=msm; an id restricts the results to one outlet or account.
filter[countries][] No A valid ISO 3166-1 country code, alpha-2 or alpha-3, for example: IT, US, IE, ITA. Subdivision codes such as US-CA are not accepted and are ignored. A full and complete list can be found here: https://en.wikipedia.org/wiki/ISO_3166-1
filter[mentioned_after] No A valid date "YYYY-MM-DD" Filter mentions created after the specified date.
filter[mentioned_before] No A valid date "YYYY-MM-DD" Filter mentions created before the specified date.
filter[key] No q scope title published_after published_before timeframe orcid identifier_list_id For more information regarding filters see Filters section below
filter[key][] No author_id department_id publisher_id doi_prefix journal_id funders handle_prefix affiliations field_of_research_codes sustainable_development_goals type open_access_types researcher_id grant_id Supports searching for multiple values. For more information regarding filters see Filters section below

Sentiment scores

filter[sentiment][] matches on the numeric score, not its name:

Score Meaning
-3 Strong negative
-2 Negative
-1 Neutral negative
0 Neutral
1 Neutral positive
2 Positive
3 Strong positive

Passing a name such as Positive rather than its score is not a valid filter value.

Data

An array of objects.

Key Type Description
id number Unique internal identifier for this mention.
type string mention
attributes object Object containing information about the mention. See Attributes for more information.
relationships object Object containing information about the author of the mention and the research outputs mentioned. See Relationships for more information.

Attributes

The available attributes object keys are as follows:

Key Type Description
url string Shows the external page where the mention can be seen.
posted-on string "YYYY-MM-DD HH:MM:SS UTC" The time when the author published their mention.
post-type string For example fbwall. See Mention types for a complete list.
summary string An excerpt of the body of the post.
external-id string The third-party identifier for the mention.
sentiment-analysis array The sentiment expressed by this mention towards each research output it mentions. Each entry is an object with a research-output-id (number) and a sentiment (string). See Sentiment analysis below.

Note

For licensing reasons an X mention carries only its identifiers: no post body, and no account handle or display name. See X data.

Sentiment analysis

The sentiment-analysis attribute is present on scored mentions, unless your organization has AI features restricted. Sentiment is currently computed for X (tweet) and Bluesky (bluesky) posts only; mentions of other types, and individual research outputs within a mention that have not been scored, are omitted from the array. When none of the mention's research outputs have been scored, the attribute is omitted entirely rather than returned as an empty array. A mention can reference more than one research output, so the array contains one entry per scored research output.

Key Type Description
research-output-id number The Altmetric ID of the research output this sentiment applies to.
sentiment string One of Strong negative, Negative, Neutral negative, Neutral, Neutral positive, Positive, Strong positive.

Relationships

The available relationships object keys are as follows:

Key Type Description
author object Use this to find the deduplicated author in the included resources. See Deduplicated object for more information.
research-outputs[] array Use these to find the deduplicated research outputs in the included resources. See Research Outputs for more information.

Deduplicated object

Key Type Description
data > id string The identifier for the object.
data > type string The type of the deduplicated object. Available types are profile research-output

    {
      "id": 699586580,
      "type": "mention",

              "id": 151229835,
              "type": "research-output"
            }
          }
        ]
      }
    }
  ],
  "included": [ ]
}

Included

A data dictionary that can be used to look up various information as part of the deduplication and disambiguation process.

Key Type Description
id string The identifier that relates to the deduplicated/disambiguated object found in within Data.
type string The type that relates to the deduplicated/disambiguated object found in within Data. Available types include: author department field-of-research grid-affiliation grid-funder sustainable-development-goal profile and supportive-grant
attributes object Type specific attributes that relate to the deduplicated/disambiguated object found in within Data. See Attributes for more information
relationships object Object containing information about the author of the mention and the research outputs mentioned. See Relationships for more information.

For example, the relationships attribute for a research-output in data might return the following object:

"data": [
  {
    "id": 69136930,
    "type": "research-output",
    "relationships": {
        "affiliations": [
          {
            "id": "grid.133342.4",
            "type": "grid-affiliation"
          }
        ]
    }
  }
]

Rather than the full details for the grid-affiliation being returned every time it appears as part of a relationship we just return its id and type. You'd use this information to query included to get any additional information to have for it.

"included": [
  {
    "id": "grid.133342.4",
    "type": "grid-affiliation",
    "attributes": {
      "name": "University of California, Santa Barbara",
      "country": "United States",
      "acronym": "UCSB"
    }
  }
]

Important

When querying the included lookup dictionary, remember to always use both the id and type as some third-party identifiers might not be unique within the Altmetric Explorer API or may apply to difference contexts.

Attributes

Provides additional information about disambiguated/deduplicated objects.

Key Type Description
title string If a journal, the official title of the deduplicated/disambiguated object.
name string The official name of the deduplicated/disambiguated object.
issns array An array of unique identifier used for print or electronic periodical publications.
country string The official name of the country relating to the deduplicated/disambiguated object.
acronym string If an organization, the GRID acronym associated with the deduplicated/disambiguated object.

Where the included object is a research-output the Altmetric Explorer API will return a research-output object. See Research Outputs - Data for a full list of attributes.

Relationships

The relationships key is only present on a research-output object. See Research Outputs - Relationships for a full list of attributes.
