Notes

• By default, results are sorted by creation date in descending order (newest first).

• The API enforces a maximum of 100 reviews that can be requested at once.

• When searching by subject with a profileId, the API finds reviews for all addresses and attestations linked to that profile.

• The score field in the response is returned as a string ("positive", "neutral", "negative") rather than a number (2, 1, 0).

• The metadata field typically contains a JSON string with a "description" field that provides additional context for the review.

• Reviews can be filtered by score type using the score parameter, which accepts an array of score types.

• If no filters are provided, the endpoint will return the most recent reviews across all subjects.

Parameters

Request Body

Responses

Success Response

Code: 200 OK

{
  "ok": true,
  "data": {
    "count": 231
  }
}

Property	Type	Description
ok	boolean	Success status
data	object	Response data
data.count	number	Number of reviews matching the filters

Example

Request

http POST https://api.ethos.network/api/v1/reviews/count \
  subject:='["profileId:1"]' \
  score:='["positive"]'

Response

{
  "ok": true,
  "data": {
    "count": 231

Notes

• This endpoint is useful for efficiently getting count information without retrieving the actual review data.

• The count reflects the total number of reviews that match the specified filters.

• When using the score filter, reviews are counted based on their score value: "positive", "neutral", or "negative".
