+      description: |-
+        Retrieves a paginated list of source maps. Send filters as query parameters,
+        not in a JSON request body. `mapkind` defaults to `js`.
+
+        For JavaScript source maps, choose one of the three request shapes below.
+
+        **Examples:** the following commands use the US1 API host. Replace the host with
+        the API host for your site, and the service, version, debug ID, and cursor with
+        values from your organization. Use `--get` so curl sends the filters in the query
+        string; `-X GET` with `--data-urlencode` sends them in the request body instead.
+
+        **1. List by service and version**
+
+        Provide both `filter[service]` and `filter[version]` to search source maps
+        indexed by service and version. Omit `search_by`.
+
+        **Pagination:** prefer cursor pagination. Omit `page[after]` and `page[number]`
+        on the first request. To get the next page, pass `meta.page.next_cursor` as
+        `page[after]`, keeping the same filters. Continue until
+        `meta.page.has_more_results` is `false`. Do not decode or modify the cursor.
+        Legacy page-number pagination is also supported, starting at `page[number]=1`.
+
+        ```bash
+        curl -sS --get "https://api.datadoghq.com/api/v2/sourcemaps/list" \
+          -H "Accept: application/json" \
+          -H "Authorization: Bearer ${DD_BEARER_TOKEN}" \
+          --data-urlencode "mapkind=js" \
+          --data-urlencode "filter[service]=my-web-service" \
+          --data-urlencode "filter[version]=1.0.0" \
+          --data-urlencode "page[size]=10"
+        ```
+
+        **2. Find a specific JavaScript debug ID**
+
+        Provide `filter[debug_id]` with a UUID. Service and version filters are not
+        required. Omit `search_by`.
+
+        **Pagination:** the lookup returns at most one result, so no pagination is
+        needed. `page[after]` is not supported.
+
+        ```bash
+        curl -sS --get "https://api.datadoghq.com/api/v2/sourcemaps/list" \
+          -H "Accept: application/json" \
+          -H "Authorization: Bearer ${DD_BEARER_TOKEN}" \
+          --data-urlencode "mapkind=js" \
+          --data-urlencode "filter[debug_id]=00000000-0000-4000-8000-000000000001"
+        ```
+
+        **3. Browse source maps indexed by debug ID**
+
+        Set `search_by=debug_id` without specifying a debug ID. Do not send service,
+        version, or filename filters in this mode.
+
+        **Pagination:** this mode requires cursor pagination; `page[number]` is not
+        supported. Omit `page[after]` on the first request. To get the next page, pass
+        `meta.page.next_cursor` as `page[after]`, keeping the same search mode and
+        filters. Continue until `meta.page.has_more_results` is `false`. Do not decode
+        or modify the cursor.
+
+        First page:
+
+        ```bash
+        curl -sS --get "https://api.datadoghq.com/api/v2/sourcemaps/list" \
+          -H "Accept: application/json" \
+          -H "Authorization: Bearer ${DD_BEARER_TOKEN}" \
+          --data-urlencode "mapkind=js" \
+          --data-urlencode "search_by=debug_id" \
+          --data-urlencode "page[size]=10"
+        ```
+
+        Next page:
+
+        ```bash
+        curl -sS --get "https://api.datadoghq.com/api/v2/sourcemaps/list" \
+          -H "Accept: application/json" \
+          -H "Authorization: Bearer ${DD_BEARER_TOKEN}" \

+          --data-urlencode "page[size]=10" \
+          --data-urlencode "page[after]=<meta.page.next_cursor>"
+        ```
+
+        For other map kinds, use `page[number]`, starting at 1.
