## Known failure modes

- No data returned for illiquid or invalid options symbols (empty data array)
- Payment failure if wallet has insufficient USDC balance
- Invalid timeframe parameter causes request rejection
- Start/end date range returns no data if outside market hours or market closed
- Symbol not found or not supported by Alpaca options data feed
