Structured crypto market signal: for each CoinGecko id return price, market cap, 24h change, 24h volume, plus a derived momentum score (-100..100), a bullish/neutral/bearish signal, and a volatility flag — enriched data an agent ingests in a trading/research loop without computing it itself. Input: ids (comma-separated).

Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 2 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
