# Basket Members

> Every member of a telemetry basket (the daily telemetry lists only 10), most representative first, with each stock's cohesion and factor scores, plus the basket's telemetry context for the report date.

Part of the **telemetry-radar** layer, a newer set of endpoints distinct from
the baskets under [Telemetry](https://docs.chicago.global/api-reference/telemetry/summary.md), including
[Basket Detail](https://docs.chicago.global/api-reference/telemetry/basket-detail.md). The daily telemetry
row lists at most 10 members per basket; this endpoint returns the full, live
membership, paired with that day's telemetry row so returns, momentum, and
quadrant match [Telemetry Baskets](https://docs.chicago.global/api-reference/telemetry/baskets.md) exactly.

Resolve `basket_id` from [Telemetry Baskets](https://docs.chicago.global/api-reference/telemetry/baskets.md)
first.

## Path Parameters

| Parameter | Type | Required | Description |
| - | - | - | - |
| `basket_id` | string | Yes | The basket to list members for. |

## Query Parameters

| Parameter | Type | Required | Default | Description |
| - | - | - | - | - |
| `date` | string | No | Latest | Telemetry report date (`YYYY-MM-DD`) for basket context. |

An unknown or inactive `basket_id` returns `404`.

## Response

Members sorted most representative first (`cohesion_z` descending, missing
last), each with its factor scores where available.

`basket` is the same object returned by
[Basket Detail](https://docs.chicago.global/api-reference/telemetry/basket-detail.md), minus its own
10-member sample. If the basket has been re-formed since this date's
telemetry row, `basket` is `null` and a `note` field explains that membership
is current but returns and quadrant are unavailable. `scores` is `null` for a
member with no scored factor row. See the response example for exact field
types.
