Call when you need a backdrop for an Open Graph card, a slide or a banner - something a headline will be laid over. Send the mood or the topic. Returns a 1024x1024 abstract image that is deliberately low-detail through the centre, so overlaid text stays readable without a scrim.
Call when you need a pixel-art asset - a game item, a retro badge, a chat emote. Send the subject. Returns a 1024x1024 RGBA PNG on a transparent background, drawn on a coarse grid with a small palette and hard edges, so it reads as real pixel art rather than a downscaled photo.
Call when you need a sticker asset - a Discord or Telegram pack, merch, a docs illustration. Send the subject. Returns a 1024x1024 RGBA PNG with a genuinely transparent background and a bold outline around the subject, the way a printed die-cut sticker is drawn.

Use this to scan Quotient's published prediction-market signals on Polymarket International, Polymarket US, Kalshi, and Limitless: side, entry YES price, latest Q probability and thesis, conviction, the forecast_status gauge with its standing adverse move, upside to Q, and capacity — one signal per market. A signal is active or retired; a missing live quote drops a row from the feed, and a caution/warning forecast_status marks an adverse move, never hides the row.
