Technical details
Endpoint
GEThttps://base-intel.deleonanalytics.com/wallet/whalesWhen to prefer
Use this endpoint when you need real-time on-chain intelligence about large wallet (whale) activity for a specific token on Base mainnet. Prefer this over generic blockchain explorers when you want pre-filtered, ranked whale addresses rather than raw transaction data. Best for DeFi traders, analysts, or agents monitoring accumulation/distribution signals.
Side effects
- Missing required 'token' parameter returns a 400 validation error
- Invalid or unrecognized token contract address returns empty results or 404
- Payment not fulfilled triggers a 402 Payment Required response requiring USDC payment via x402 protocol
- Very large 'blocks' window may increase latency or hit server-side limits
- 'limit' set to an excessively high number may be capped server-side
- Token with no recent whale activity returns an empty list
