# Quant Galore Momentum Index constituents: the daily holdings of a rules-based

`GET /v1/quant-galore-momentum-index`

## Request

- Base URL: `https://api.alphanume.com`
- URL: `https://api.alphanume.com/v1/quant-galore-momentum-index`
- Auth: one of:
  - API key in header `X-API-Key`
  - HTTP bearer

Quant Galore Momentum Index constituents: the daily holdings of a rules-based
12-1 momentum strategy (long the highest-momentum US names, refreshed on a fixed
schedule). One row per constituent per day: date, ticker, and rank (1 = strongest).
History is point-in-time -- each day shows exactly what the index held then, so
backtests are free of look-ahead.

Use it to mirror the index, source high-momentum candidates, or study momentum
portfolio turnover. Query a single `date` for that day's basket, or a range to see
how the basket evolved.

Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or
DATE_RANGE_RESTRICTED error means the key's plan does not cover the request --
it does not mean the data is missing.

## Query parameters

- `date` string
- `date_gte` string
- `date_lte` string
- `date_gt` string
- `date_lt` string

## Response `200`

Matching rows.

- Envelope
  - `count` integer, required
  - `data` object[], required

## Other responses

- `400`: Invalid or conflicting query parameters.
- `401`: Missing or unrecognized API key.
- `403`: PRO_SUBSCRIPTION_REQUIRED: the key's plan does not include API access; every endpoint requires an active Pro subscription. DATE_RANGE_RESTRICTED: a legacy free-tier key asked for dates outside its window. In both cases the data is not missing.
- `429`: Rate limit exceeded (600/min); the body carries retry_after_seconds.
