# Next-Day Movers: each trading day, the US equities a volatility model ranks most

`GET /v1/next-day-movers`

## Request

- Base URL: `https://api.alphanume.com`
- URL: `https://api.alphanume.com/v1/next-day-movers`
- Auth: one of:
  - API key in header `X-API-Key`
  - HTTP bearer

Next-Day Movers: each trading day, the US equities a volatility model ranks most
likely to make an outsized price move in the *next* session. Rows carry the ticker,
the list date, and -- once the next session has traded -- the realized outcome
(`return` = signed next-day return, `absolute_move` = unsigned magnitude), so the
dataset doubles as its own scorecard.

Use it to focus long-gamma / straddle / breakout attention on a short daily list,
or to backtest the signal against realized moves over a date range.

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.
