How to use

Use the web_fetch tool to query the InvestLog API. The system automatically detects the stock ticker and selects the right data to return.

Basic query

web_fetch url="https://api.investlog.ai/api/v1/query?query=Is+NVDA+overvalued" extractMode=text

Query with specific skill and symbol

For more precise results, specify the skill name and ticker:

web_fetch url="https://api.investlog.ai/api/v1/query?query=AAPL+earnings&skill=financials&symbol=AAPL" extractMode=text

Compound analysis (multiple calls)

For comprehensive stock analysis, make multiple calls to combine different data:

# 1. Get current price and valuation
web_fetch url="https://api.investlog.ai/api/v1/query?query=NVDA+valuation&skill=valuation&symbol=NVDA" extractMode=text

# 2. Get analyst ratings and price targets
web_fetch url="https://api.investlog.ai/api/v1/query?query=NVDA+analyst+ratings&skill=analyst-view&symbol=NVDA" extractMode=text

# 3. Get recent earnings performance
web_fetch url="https://api.investlog.ai/api/v1/query?query=NVDA+earnings+history&skill=financials&symbol=NVDA" extractMode=text

Combine the results from multiple calls to provide a thorough analysis.
