# Api V2 Gex Strike-Profile-Timeseries Get

`GET /api/v2/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/v2/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.

      - `net_gamma` string, required
      - `call_oi` integer, required
      - `put_oi` integer, required
  - `freshness` Freshness, required: The v2 freshness envelope. Present on every ``/api/v2/*`` response.
    - `evaluated_at` string, date-time, required: When the API evaluated this response (server wall clock, UTC). Endpoint-health signal: advances on every request even when the underlying data is unchanged.
    - `generated_at` string, date-time, required: When the served data was computed. Equals the snapshot stamp for cycle-backed endpoints, or evaluated_at for endpoints computed on demand for this request.
    - `source_timestamp` string, date-time, nullable: Timestamp of the upstream market observation the payload derives from. This is what freshness_status is measured against. Null when the endpoint has no upstream feed or returned no rows.
    - `latest_event_at` string, date-time, nullable: Newest event timestamp present in the payload (last bar, last trade, last scored row). Best-effort on very large responses, which are sampled rather than fully walked.
    - `age_seconds` number, nullable: evaluated_at - source_timestamp, in seconds. Null when source_timestamp is null.
    - `market_session_status` string, required: pre-market | regular | after-hours | closed (US/Eastern).
    - `expected_update_cadence` string, nullable: ISO-8601 duration for how often this endpoint's data is expected to change right now, e.g. PT60S. Null means no updates are expected (weekend, holiday, or a feed that only runs during the session).
    - `expected_update_cadence_seconds` number, nullable: expected_update_cadence as a number of seconds.
    - `cadence_profile` string, required: Identifier of the cadence class this endpoint belongs to, e.g. analytics_cycle. Stable across releases; the seconds behind it may be retuned.
    - `stale_after` string, date-time, nullable: Instant after which this payload should be treated as stale. Null whenever expected_update_cadence is null.
    - `freshness_status` 'fresh' | 'aging' | 'stale' | 'session_closed' | 'static' | 'unknown', required: The rolled-up freshness verdict for one response. ``fresh`` ``source_timestamp`` is within one expected update cadence. ``aging`` Past one cadence but not yet past ``stale_after`` — the grace band that absorbs normal cycle jitter. Not an error; a client that polls faster than the cadence sees this routinely. ``stale`` Past ``stale_after`` while updates *were* expected. This is the actionable state: the feed behind this endpoint is late. ``session_closed`` A feed-backed endpoint whose feed is not due to produce anything right now (weekend, holiday, or a feed that only runs during the session). The payload is the last good value — deliberately NOT reported as ``stale``, because an overnight consumer polling a closed market is not observing a fault and should not page on it. ``static`` The endpoint is not feed-backed at all: completed history, or a result computed from the caller's own inputs. Age here carries no health meaning and never becomes a fault. ``unknown`` No source timestamp could be resolved from the payload (e.g. a pure calculator, an admin endpoint, or an empty result set). A consumer should fall back to ``evaluated_at`` for endpoint health and make no claim about data age.
