get_market_structureThe 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 pre…
get_regimeOnly 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.
list_history_datesFree catalog of available historical SPX market-structure replay dates. No API key required; actual replay datasets are paid.
get_dayThe 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.
get_regime_segmentsOnly 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.
subscribe_eventSubscribe 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; i…
unsubscribe_eventRemove an event subscription by its subscription_id (the id returned when the subscription was created).
list_subscriptionsList this agent's active event subscriptions.
get_field_guideStatic, 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 ve…
get_access_optionsFree: current prices and the accountless access steps; no website account required.
create_guest_keyCreates 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…
get_credit_balanceFree balance check for the API key in this connection's HTTP header; takes no key argument.
create_credit_checkoutCreate 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.
Headers
| Name | Description |
|---|---|
X-API-KeyOptional, secret | Optional zdte.ai API key (one key covers MCP and the REST v1 mirror). OAuth clients are asked to Connect instead; without either, a delayed preview and the free tools work. |
