Example prompt: Pull the WhaleFlow smart-money tape for pump.fun mint So11111111111111111111111111111111111111112 — show me net SOL accumulation vs distribution, how many unique whales are active, and the latest large trades.

## When to prefer this

Choose this endpoint when you need real-time smart-money intelligence specifically for pump.fun mints on Solana — particularly net SOL accumulation vs distribution and individual large trade visibility. Prefer it over generic on-chain explorers when you want a pre-aggregated whale-activity summary without parsing raw transaction data yourself. Best suited for trading agents, alpha bots, or risk screens that need a fast signal on whether sophisticated wallets are entering or exiting a position.

## Known failure modes

- Invalid or unrecognized mint address returns an error or empty result
- Mint has no recorded whale activity, returning zero counts and empty trade list
- Rate limiting or payment failure at $0.002 USDC per call if balance is insufficient
- Stale data if the crowdsourced tape has not been recently updated for the requested mint
- Network or upstream Solana RPC issues causing delayed or missing data
