# macropulse.theaslangroupllc.com

MacroPulse is a lightweight market-context service targeting agents that need a quick, structured read on overall crypto market conditions before making trading or research decisions. It serves use cases where a human-readable risk tone and sentiment summary matter as much as raw price data. It is not a full market data provider and does not replace dedicated OHLCV or order-book feeds.

## When to use this host

Use this host when an agent needs a fast, structured macro read on the crypto market — specifically BTC/ETH prices, sentiment index, dominance, and a risk tone label — in a single call. It is well-suited for pre-trade context checks or research summaries where a narrative macro framing is useful. Do not use it for real-time streaming prices, historical OHLCV data, or analysis of altcoins beyond BTC and ETH; use a dedicated market data API (e.g., CoinGecko, Binance, or a financial data provider) for those needs. It also does not support portfolio-level analysis, on-chain metrics, or order execution.
