Tips for Agents

• No API key needed to start — market data endpoints work without auth (20 req/hour). Register at POST /register when you need higher limits
• Portfolio, journal, and watchlist endpoints require an API key — register first if you need these
• Use /v1/brief for morning market summaries — it combines everything in one call
• Use /v1/screen for building watchlists or alert conditions
• Use /v1/compare when the user asks to compare specific tickers
• Use /v1/asset/{symbol}/live only when the user needs a fresh quote — it has stricter rate limits
• Parse the meta.requestsRemaining field to manage your rate limit budget
• The highlights array in /v1/brief contains pre-formatted natural-language summaries
• Use /v1/portfolio when the user asks about their holdings, P&L, allocation, or portfolio performance
• Use POST /v1/portfolio to add holdings — the id is generated server-side, use it for subsequent deletes
• Use /v1/portfolio/performance?range=YTD&benchmarks=SPY to answer "how am I doing vs the S&P?"
• Use /v1/journal to log trade rationale — attach a symbol and tags for better organization
• Portfolio, journal, and watchlist endpoints return Cache-Control: private, no-store — do not cache these
• Use /v1/watchlist to manage symbol watchlists — create a list, then use /v1/compare or /v1/screen with those symbols
• Use PATCH /v1/watchlist/{id} with addSymbols/removeSymbols to manage symbols without replacing the whole list
• Use /v1/news?category=crypto to get relevant headlines before making trade decisions
• Use /v1/asset/{symbol}/history for technical analysis — stocks get full OHLCV, crypto gets close + volume
• Use /v1/earnings?symbols=AAPL before earnings season — check EPS estimates and recent quarter surprises
• Use /v1/earnings?week=current for a quick weekly earnings calendar (zero real-time API calls)
• Use /v1/portfolio/card to generate a shareable portfolio image — pipe to a file with -o card.png
• Use /v1/news?symbol=AAPL to get news specifically about an asset — searches all feeds by symbol and company name
• Use /v1/macro for a quick macro dashboard — BTC, ETH, S&P 500, Nasdaq, Gold, Oil, DXY, VIX, and 10Y in one call
• Use /v1/asset/{symbol}/details for deep fundamental analysis — earnings, analyst targets, insider activity, SEC filings, and ETF holdings in one call
• Use /v1/asset/{symbol}/options for derivatives analysis — get the full options chain with calls, puts, OI, IV, and all available expirations. Combine with /v1/asset/{symbol}/live for delta-neutral strategies
• Use /v1/trending for live market movers — most active, top gainers, top losers. Pre-cached from Yahoo screener, no live rate limit cost. Filter by ?section=gainers or limit with ?count=5
• Use /v1/asset/{symbol}/fundamentals for historical financial analysis — revenue trends, margin evolution, balance sheet health over 5 years. Use ?type=quarterly for recent quarter-by-quarter trends
• Use POST /v1/ask for complex natural language queries — it parses intent and routes to the right data. Requires API key, counts against AI daily limit
