// multi-step analysis

Chain calls. Build context.

Pull a summary, check for historical band transitions, then monitor your watchlist for changes. Each method returns typed market-state data you can branch on directly.

client.summary("AAPL")

Full categorical breakdown — trend, momentum, volatility, fundamentals

client.summary("AAPL", { field: "rsi_zone", band: "deep_oversold" })

Historical band transitions for RSI entering deep oversold

client.watchlistChanges()

State changes across your monitored tickers

// state changes

Track state changes effortlessly.

Most market data APIs return point-in-time snapshots. TickerDB tracks state transitions — your agent sees what changed, not just what is.

typescript

const { data } = await client.watchlistChanges();

// what your agent sees

What your agent sees.

Every tool returns categorical facts — not raw OHLCV data. Your agent can branch on "oversold" without needing to know what RSI > 70 means.
