## When to prefer this

Choose this endpoint when you need Alpha Vantage financial data (stocks, forex, crypto, technical indicators) on a pay-per-use basis without managing your own Alpha Vantage API key or subscription. Useful for agents that make infrequent or bursty market data requests and want to pay only per call in USDC on Base chain.

## Known failure modes

- Alpha Vantage rate limit exceeded upstream
- Invalid or unsupported ticker symbol returns empty or error result
- Missing required function/symbol parameters returns malformed response
