Paid: Market Heatmap

three.ws Market Heatmap — pay $0.002 USDC per call for a normalized snapshot of the top coins by market cap: rank, price, 1 h / 24 h / 7 d momentum, market cap, and 24 h volume per coin, plus market-breadth statistics (advancers vs decliners, average and median 24 h move) that tell an agent whether strength is broad or narrow. Dual live sources with automatic failover (CoinGecko primary, CoinPaprika fallback) so a single upstream rate-limit never breaks a paid call. Size the board with ?limit=1..100. Refreshed every 60 seconds; upstream outages refuse before settlement.
