get_market_structure | The full current SPX dealer market structure, the largest realtime read: walls, gamma flip, net GEX, regime and the strike-level detail below. Current computed SPX dealer market structure (walls, gamma flip, net GEX, regime), recomputed ~every 10s during market hours: scored pressure-point strike ladder, implied 50%/80% forecast-band ranges, strike activity (volume/OI), and VIX term-structure cont params: none |
get_regime | Only the current SPX dealer regime label and its confidence, a small read for checking whether conditions have changed; no walls, gamma flip, net GEX or strike detail. Realtime with an API key; without a key this serves a delayed preview. params: none |
list_history_dates | Free catalog of available historical SPX market-structure replay dates. No API key required; actual replay datasets are paid. params: none |
get_day | The full market-structure history of one past trading day, the larger replay: the intraday timeline (walls, gamma flip, net GEX, regime, spot) plus a day summary. One replay date (YYYY-MM-DD) per call. Data only -- not investment advice or a trade recommendation. params: date* |
get_regime_segments | Only how the dealer regime changed during one past trading day, the compact replay: a list of regime segments with their start and end times; no walls, gamma flip, net GEX or spot. One replay date (YYYY-MM-DD) per call. params: date* |
subscribe_event | Subscribe a callback URL to a market-structure event (zero_gamma_flip | new_wall | regime_transition). The answer includes signing_secret, shown only once: store it. Each time the event fires, the callback receives an HTTPS POST whose JSON body has id (one per delivered event; ignore a repeat), event, at (ISO 8601 UTC time of the market snapshot the event was seen in), subscription_id and data, th params: event*, callback_url* |
unsubscribe_event | Remove an event subscription by its subscription_id (the id returned when the subscription was created). params: subscription_id* |
list_subscriptions | List this agent's active event subscriptions. params: none |
get_field_guide | Static, versioned dictionary of every field this surface emits: unit, value set where the field has a fixed one, and a one-sentence meaning, plus the shared response conventions (tier, delay, timestamps, and how missing data is reported) and a changelog. No inputs; static per version. params: none |
get_access_options | Free: current prices and the accountless access steps; no website account required. params: none |
create_guest_key | Creates a zero-credit API key, returned once and not shown again. When the response says connection_authenticated, this MCP session already uses the key; other connections authenticate with an HTTP Authorization: Bearer header. No arguments. For OAuth-capable clients, a Connect prompt appears automatically the first time an account or paid tool is called, with no website account needed, so no key params: none |
get_credit_balance | Free balance check for the API key in this connection's HTTP header; takes no key argument. params: none |
create_credit_checkout | Create a payment link that adds prepaid credits to the authenticated key; a person opens it to pay. Does not charge or fund anything until payment is authorized and confirmed. params: credits* |
