GET /indexes

Use the GET /indexes endpoint to return a list of indexes.

Prerequisites

1. Add an API key.

2. Generate an access token.

Base URL

Direct all requests to the GET /indexes endpoint to the following base URL:

https://{tenant-id}.amperity.com/api/indexes/

Rate limit

A rate limit is the number of requests that may be made to the Amperity API in a given time period.

The Amperity API supports requests to endpoints that do not exceed a rate of 10 requests per second. Response times will vary by endpoint and the complexity of data that is returned by the response. Some requests may take seconds to return.

Requests to the Amperity API that exceed 10 requests per second may return an error response with an HTTP 429 status code.

Requests

A request to the GET /indexes endpoint is similar to:

curl --request GET \
       'https://tenant.amperity.com/api/indexes \
     --header 'amperity-tenant: {tenant}' \
     --header 'api-version: 2025-07-31' \
     --header 'Authorization: Bearer {token}'

(This example is formatted for readability in a narrow page layout.)

Request parameters

The following table describes the parameters that may be used with the GET /indexes endpoint.

Parameter	Description
limit	Integer. Optional. The maximum number of records to include in a single page of results. Default value: 25.
next_token	String. Optional. An opaque token that is used to paginate results. Omit the next_token property to return the first page. Use the cursor value for next_token that was returned in a response to view the next page of results. For example: ABCd1fghIJk2l3M Note The possible values for next_token are returned within the 200 response. Important The value for next_token cannot be NULL.
with_total	Boolean. Optional. Set this value to true to include a total count of all results. Default value: false. Note Obtaining the total count of all results can be an expensive operation when there is a high number of pages in the results set.

Responses

A response from the GET /indexes endpoint will match an HTTP status code. A 200 response will contain the results set. A 4xx response indicates an issue with the configuration of your request. A 5xx response indicates that the endpoint is unavailable.

200 OK

The 200 response returns a list of indexes.

{
  "data": [
    {
      "id": "{id}",
      "name": "{name of index}",
      "description": "{description of index}",
      "created_at": "{timestamp}",
      "updated_at": "{timestamp}"
    }
  ],
  "next_token": "string",
  "total": 0
}

For example:

{
  "data": [
    {
      "id": "idx-xyz789",
      "name": "loyalty_members",
      "description": "Profiles from the loyalty program",
      "created_at": "2025-07-30T22:16:04.409Z",
      "updated_at": "2025-07-30T22:16:04.409Z"
    }
  ],
  "next_token": "string",
  "total": 0
}
