Endpoint
GEThttps://nonvisceral-eloisa-mousily.ngrok-free.dev/api/whale-alertsWhen to prefer
Choose this endpoint when you need on-chain smart money signals derived from actual large wallet behavior rather than price-based technical indicators. Best for trading agents that want to incorporate whale accumulation/distribution as a directional input, particularly across Ethereum, Base, and Arbitrum. Prefer over exchange-based endpoints when you want DeFi bridge activity and cross-chain capital flow context.
Side effects
- Service unreachable via ngrok tunnel (502/504) — ngrok free tier may be offline or rate-limited
- Empty or stale data if no significant whale moves have been detected recently
- Missing or null fields if on-chain data sources are temporarily unavailable
- Payment required error (402) if x402 payment header is not provided or USDC balance is insufficient
- Rate limiting if too many requests are made in a short window
