Filter fields include `customer_identifier`, `name`, `email`, `number_of_requests`, `total_tokens`, `total_cost`, and `active_days`. Reference: https://respan.ai/docs/apis/users/list-users ## Authentication - `Authorization` header (bearer token, required) — Use your Respan API key for Respan API authentication. Enter only the Respan API key value; clients send Authorization: Bearer \. For /api/responses, provider credentials such as Perplexity, OpenAI, or Azure OpenAI go in Settings -> Providers or respan\_params.credential\_override in the request body, not in this authentication field. - `Authorization` header (bearer token, required) — Use a dashboard JWT only for dashboard-authenticated endpoints. Respan API-key endpoints use the respanApiKey auth field instead. ## Request ### Query parameters - `page` (integer, optional, default: 1) — Page number. - `page_size` (integer, optional, default: 50) — Number of users per page. Maximum is 1000. - `sort_by` (string, optional, default: -first_seen) — Sort field. Prefix with `-` for descending. Common values include `customer_identifier`, `email`, `name`, `-first_seen`, `-number_of_requests`, and `-total_cost`. - `environment` (enum, optional) — Optional environment filter. If omitted, the backend uses the environment implied by your auth context when applicable. - Allowed values: `prod`, `test` ### Body (application/json) This endpoint expects an object. - `filters` (Filters, optional) — Each key is a field to filter on, and each value is a condition: `{"": {"operator": "", "value": [...]}}`. A user must match every condition. To set two conditions on one field, such as a range, pass a list of conditions. **Operators:** `""` (equals, the default), `not`, `in`, `not_in`, `lt`, `lte`, `gt`, `gte`, `contains`, `not_contains`, `icontains` (ignores case), `startswith`, `not_startswith`, `endswith`, `not_endswith`, `empty`, `not_empty`. Put values in a list: `""` and `in` match any of the listed values, and `not` and `not_in` match none of them. Other operators take one value; for `empty` and `not_empty`, send `[""]`. **Fields:** `customer_identifier`, `name`, `email`, `environment`, `number_of_requests`, `total_cost`, `total_tokens`, `total_prompt_tokens`, `total_completion_tokens`, `average_latency`, `average_ttft`, `active_days`. Unsupported fields, including `metadata__`, return a 400 error. **Example:** ```json { "total_cost": {"operator": "gte", "value": [10]}, "email": {"operator": "endswith", "value": ["@acme.dev"]} } ``` ## Response ### 200 Paginated list of users. - `count` (integer, required) — Number of results on this page, not the total. Request pages until `next` is null to get every result. - `results` (list of ApiUsersListPostResponsesContentApplicationJsonSchemaResultsItems, required) — Users for the current page. - `next` (string, optional, nullable) — Next page URL. - `previous` (string, optional, nullable) — Previous page URL. ## Errors ### 400 Bad Request Error Bad Request - `detail` (string, optional) ### 403 Forbidden Error The API key is missing, invalid or expired. - `detail` (string, required) ### 413 Content Too Large Error The query exceeded a memory or execution-time resource limit. - `detail` (string, optional) ### 429 Too Many Requests Error Rate Limited - `detail` (string, optional) ### 500 Internal Server Error Internal Server Error - `detail` (string, optional) ## Types ### Filters Each key is a field to filter on, and each value is a condition: `{"": {"operator": "", "value": [...]}}`. A result must match every condition. To set two conditions on one field, such as a range, pass a list of conditions. **Operators:** `""` (equals, the default), `not`, `in`, `not_in`, `lt`, `lte`, `gt`, `gte`, `contains`, `not_contains`, `icontains` (ignores case), `startswith`, `not_startswith`, `endswith`, `not_endswith`, `empty`, `not_empty`. Put values in a list: `""` and `in` match any of the listed values, and `not` and `not_in` match none of them. Other operators take one value; for `empty` and `not_empty`, send `[""]`.
