Tools
| Tool | Description | Behaviour |
|---|---|---|
| create_credit_checkout | Create a Stripe Checkout link for the authenticated key. Does not charge or fund until payment is authorized and confirmed. Return and check get_credit_balance. | Changes data |
| create_guest_key | Create a zero-credit API key, returned once, and save it securely. When the response says connection_authenticated, this MCP session is already using the key: continue with create_credit_checkout. Otherwise, and for new connections, configure HTTP Authorization: Bearer and reconnect. No arguments. | Changes data |
| get_access_options | Free pricing and accountless access instructions. Start here; no website account required. | Read-only |
| get_credit_balance | Free balance check for the API key in this connection's HTTP header. Never pass a key as an argument. | Read-only |
| get_day | Per-day SPX market-structure timeline + summary for one replay date (YYYY-MM-DD). Data only -- not investment advice or a trade recommendation. | Read-only |
| get_field_guide | Static, versioned dictionary of every field this surface emits: unit, value set where the producer has one, and a one-sentence meaning, plus the shared response conventions (tier, delay, timestamps, and how missing data is reported). No inputs; call once per session. | Read-only |
| get_market_structure | 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 context. Also the 0DTE ATM-straddle expected move and its session fence, max pain, the running session open/high/low with the prior close and gap, order-flow measurements, a top-10 net-GEX strike profile, and chain vanna/charm totals with a top-10 strike ladder. Realtime requires a funded API key, no website account needed: call create_guest_key, then create_credit_checkout, then get_credit_balance (account holders can also buy at https://zdte.ai/agent/credits); without a key this serves a delayed headline preview only (regime, spot, walls, gamma flip, net GEX). Data only -- not investment advice or a trade recommendation. | Read-only |
| get_regime | Current SPX dealer regime label + confidence only. Realtime with an X-API-Key; without a key this serves a delayed preview. | Read-only |
| get_regime_segments | Compressed dealer-regime segment tape for one replay date (YYYY-MM-DD). | Read-only |
| list_history_dates | Free catalog of available historical SPX market-structure replay dates. No API key required; actual replay datasets are paid. | Read-only |
| list_subscriptions | List this agent's active event subscriptions. | Read-only |
| subscribe_event | Subscribe a callback URL to a market-structure event (zero_gamma_flip | new_wall | regime_transition). | Changes data |
| unsubscribe | Remove an event subscription by id. | Destructive |
