Call cc.trade_builder — Takes natural language or structured trade ideas, fetches live market context, and generates fully executable order parameters with AI reasoning. Purpose: Takes natural language or structured trade ideas, fetches live market context, and generates fully executable order parameters with AI reasoning. Behavior: mostly READ (plan/validate). WRITE/destructive only when action=execute — that can submit live orders. Prefer action=plan first. Auth: X-Api-Key or x402 payment proof (X-PAYMENT / __x_payment). Anonymous unauthenticated calls receive HTTP 402 with payment accepts. Cost: $0.02 USDC per successful call (x402 Base USDC pay-per-use or prepaid X-Api-Key balance). Linked Connect keys are free. This is billing, not a side effect. Rate limit: 10/min (per API key). Tier: premium. Returns: Complete trade specification: symbol, side, size, leverage, entry type, TP levels, SL level, AI reasoning for each parameter. Guidelines: Prefer paper/simulation paths. For live money require explicit human confirmation (confirm_live / action=execute). Report real HTTP errors; never invent proxy failures.
