Store the hash for the book you trade (books.spx for the S&P 500, books.qqq for the Nasdaq-100) or pass ?syms=NVDA,AMD for per-name hashes of just your watchlist. Buy a paid read only when YOUR hash changes; unchanged means the board is MATERIALLY unchanged (regime, ladder, candidate set — prices and %-moves still tick; movers/leaders/topvol re-rank on price and are outside this hash). If-None-Match gives a 304.","what_it_covers":"Per book: regime mode, permission ladder rung, and the firing/ready candidate set. Per symbol: entry state, opportunity score, leadership flag. Never the publish timestamp — the board republishes about every 5 minutes without the state meaningfully changing.","buy_when_it_moves":{"cheapest_answer":"https://coil.trade/api/crypto/gate ($0.001)","regime":"https://coil.trade/api/board/regime ($0.005)","one_or_more_names":"https://coil.trade/api/board/name?sym=NVDA,AMD ($0.005, up to 10)","everything_at_once":"https://coil.trade/api/board/brief ($0.02)"},"free_alternatives":"https://coil.trade/api/board/free (delayed board) · https://coil.trade/mcp (MCP)"}
