Example prompt: Can you check the BBX whale entry signal for this token — I want to know if large holders are currently accumulating before I take a position?

## When to prefer this

Choose this endpoint when you need to detect large-holder (whale) accumulation or entry signals on-chain before making a trading decision, particularly for tokens where smart-money moves precede retail price action. Prefer it over generic price feeds when the specific goal is identifying asymmetric entry opportunities driven by whale behavior.

## Known failure modes

- Invalid or unrecognized token address returns 400 error
- Unsupported blockchain network returns validation error
- Insufficient on-chain data for the token returns empty or low-confidence signal
- Payment not processed correctly returns 402 Payment Required
- Rate limiting or server overload returns 429 or 500 error
