# What the standard basket has cost at each chain, day by day

`GET /v1/insights/basket/history`

## Request

- Base URL: `https://supermcp.co.il`
- URL: `https://supermcp.co.il/v1/insights/basket/history`
- Auth: none required

Recorded totals, not a reconstruction: each point is the figure this API published that day, and the last point of every series is the total `/v1/insights/basket` returns right now. Only chains that stock the whole basket appear, because a total over fewer lines is smaller for carrying less and is not comparable with the rest. Days with no record are absent rather than interpolated, so a step in `points` is always a movement between two published totals. History begins 2026-08-16; `watchingSince` is null before anything was recorded.

## Response `200`

OK

## Other responses

- `400`: Bad request. Query parameters are validated strictly: a parameter this document does not list is rejected, and `details[].keys` names it. A misspelled filter used to be dropped silently, which answered a question nobody asked with a plausible list of products.
- `401`: Unauthorized
- `404`: Not found
- `429`: Rate limited
