Technical details
Endpoint
GEThttps://x402ninnin.vercel.app/api/whale/%7Bchain%7DWhen to prefer
Use this endpoint when an agent needs to surface large wallet movement data or whale signals on a specific supported chain (Base, Solana, Arbitrum). Prefer this over generic block explorers when you want pre-filtered alpha-signal-style data rather than raw transaction history.
Side effects
- Unsupported chain identifier returns empty or error response
- movements array is empty when no whale activity is detected
- Invalid chain parameter may result in a 400 or malformed response
- Payment not accepted results in 402 Payment Required
- Rate limiting or service unavailability returns 5xx error
