get_field_guide
Field Guide (Schema Reference)
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 Idempotent
Input schema 
{'type': 'object', 'properties': {}, 'additionalProperties': False}
get_market_structure
SPX 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 X-API-Key (create one 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.
