# Get Strike Profile Timeseries

`GET /api/gex/strike-profile-timeseries`

## Request

- Base URL: `https://api.zerogex.io` (the document declares no server; this is the origin it was published from)
- URL: `https://api.zerogex.io/api/gex/strike-profile-timeseries`
- Auth: HTTP bearer

Aligned per-bucket Strike-Profile timeseries used by the rewind chart.

Returns ``window_units`` time buckets ASCENDING (most recent last) for
``symbol`` at the requested ``timeframe``.  Each bucket carries:

  * the underlying OHLC inside the bucket (from ``underlying_quotes``);
  * the bucket's ``gamma_flip`` from the representative
    ``gex_summary`` row;
  * ``call_wall`` / ``put_wall`` computed live for the bucket from
    the same (expiration-filtered, summed-by-strike) gamma rows the
    bucket's bars render, against the bucket's own close — via the
    canonical :func:`src.analytics.walls.compute_call_put_walls`
    helper (single source of record).  ``expirations=all`` yields
    the cross-expiration aggregate walls (matches
    ``/api/gex/summary``); a specific set yields walls scoped to
    that set's gamma alone;
  * ``pin_strike`` / ``pin_confidence`` as of the bucket's close,
    from the representative ``gex_summary`` row.  Unlike the walls
    and the flip these are NOT scoped by ``expirations``: the pin is
    0DTE-by-construction and whole-chain by definition, so it reads
    the same in every expiration scope (matching the live surfaces,
    where the pin does not move with the Expiry selector).  Both are
    ``null`` when the bucket has no active pin and on rows written
    before the pin columns shipped — draw no line, never a zero;
  * every strike's gamma exposure in the same dollar-GEX units
    ``/api/gex/by-strike`` uses (``γ × OI × 100 × S² × 0.01``),
    evaluated against the bucket's own ``close`` so the surface
    matches each bucket's candlestick.

``expirations=all`` sums strike gamma / OI across all expirations per
(bucket, strike).  A comma-separated list of ``YYYY-MM-DD`` dates
restricts the strikes payload to that set (summed across the set).
For a specific set the bucket ``gamma_flip`` is recomputed from the
summed-by-strike gamma (the aggregate spot-shift flip can't be rebuilt
for a subset); ``all`` keeps the canonical ``gex_summary`` flip.  Names
in the strikes payload follow the request shape (``call_gamma`` /
``put_gamma`` / ``net_gamma``) but the values are the dollar-GEX
quantities, not raw gamma — see the per-row docstring on
``StrikeProfileStrike``.  Any unparseable entry is a 400.

``delay_minutes`` ends the window at the newest bucket at least that old
(see src/api/delayed_read.py).

## Query parameters

- `symbol` string
- `timeframe` '1min' | '5min' | '15min'
- `window_units` integer
- `expirations` string: 'all' to aggregate strikes across every expiration (same basis as the live /api/gex/by-strike with Expiry All), or a comma-separated list of YYYY-MM-DD expiration dates to restrict the strikes payload to that set (summed across the set).
- `delay_minutes` integer: Serve the newest data that is at least this many minutes old instead of the latest. 0, the default, is the live read.
