Get the conformal-calibrated 30-day price forecast AND letter grades for a single card in ONE free call. Pass either a card_name (resolved to the best match) or a TCGplayer product_id. FREE — no payment required. Returns an agent-complete object: price, as_of, regime, point (median 30d), move_pct, prob_up, band50_pct, band90_pct, var95_pct, var99_pct, low90, high90, safe_hold grade (A+..F), momentum grade (A+..F or "NA" on a drift spike), drift_spike, image_url, card_url, and a one-line plain_english read (e.g. "~12% chance it's below $Y in 30 days; Safe-Hold B, Momentum A"). Use this when a user asks "is this card a safe hold?", "what's the 30-day outlook?", "how risky is X?", or wants a quick grade on a card. Tip: GET /api/v1/forecast (no args) returns the free board of the top ~200 cards if the user wants a market overview.
