OpenAPI + AsyncAPI spec sync from v3.19.0 → v3.20.0 (#385). Adds the
new GET /events/fee_changes endpoint plus three smaller additive
changes upstream re-published into 3.20.0 after the drift issue was
filed (the OpenAPI checksum in #385 is therefore stale; the AsyncAPI
checksum still matches).

Added

  • events.fee_changes() / fee_changes_all() (sync + async) for
    GET /events/fee_changes — the new paginated event-level fee-override
    feed (event_ticker, limit, cursor). Returns Page[EventFeeChange]
    (and an auto-paginating iterator). EventFeeChange exposes
    fee_type_override / fee_multiplier_override, both present-but-None
    when an override is cleared.
  • is_block_trade query param on markets.list_trades /
    list_all_trades (+ deprecated list_trades_all) and
    historical.trades / trades_all. Omit for all trades, True for
    only block trades, False for only non-block.
  • Trade.is_block_trade (bool) — new spec-required, non-nullable
    response field; a missing key raises so a schema regression surfaces.
  • WebSocket event_fee_update message on the existing
    market_lifecycle_v2 channel (EventFeeUpdateMessage /
    EventFeeUpdatePayload). subscribe_market_lifecycle() now yields
    MarketLifecycleMessage | EventFeeUpdateMessage. Channel count is
    unchanged (still 11) — this is a second message type on an existing
    channel. Behavioral note for existing subscribers: discriminate on
    .type before reading payload fields — an EventFeeUpdatePayload has no
    market_ticker, so naive access raises AttributeError. See the
    migration callout in docs/websockets.md.

Internal

  • specs/openapi.yaml (sha256
    b72a2aa138695d810f6ca85096bfe19e1b66ba5e9b2ed37753be284b5288d271)
    and specs/asyncapi.yaml (sha256
    2f72d0a3fd25fe331210ed300f03ad4c1fedcb561b3ab425046b2dca6f4683ec)
    snapshots bumped; kalshi/_generated/models.py regenerated.
  • Spec also relaxed CreateOrderV2Request.client_order_id and
    EventData.product_metadata from required to optional, and added
    ApiKeyScope / FeeType enums. No SDK-facade change: the V2 order
    keeps client_order_id required by design, Event.product_metadata
    already tolerated server omission, and API-key scopes stays str
    for forward-compat.
  • README + docs/index.md banners bumped to "99 operations … OpenAPI
    v3.20.0".
