`create_guest_key`Creates a zero-credit API key, returned once and not shown again.

`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.

`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 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. The full realtime structure needs a funded zdte.ai API key (no website account needed); without a key this returns a delayed headline preview (regime, spot, walls, gamma flip, net GEX).

`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, the event's values: zero_gamma_flip has gamma_flip and spot, new_wall has which (call_wall or put_wall) and level, regime_transition has from and to. To verify a delivery, read the ZDtE-Signature header, t=<unix seconds>,v1=<hex>: compute HMAC-SHA256 keyed with signing_secret exactly as returned (its text as bytes; do not hex-decode it) over t, a period and the raw request body, compare it with v1 in constant time, and reject the delivery if t is more than 5 minutes old.
