Witnos wallet intelligence: full scored profile for any Base or EVM wallet, the deep read behind a verify. Whale score (0-1 composite of spend velocity, service diversity, premium ratio, repeat rate), behavioral cluster, x402 spend graph, counterparty check, payment history, top services, risk assessment and temporal patterns. A wallet tracker and profiler built from 18,000+ profiled wallets.
Output
A structured profile including a composite whale score (0–1) derived from spend velocity, service diversity, premium ratio, and repeat rate; a behavioral cluster label; itemized payment history; list of top services used; risk assessment; and temporal activity patterns — drawn from Crest's proprietary database of 18,000+ profiled wallets on Base mainnet.

Example prompt

Technical details
Endpoint
GEThttps://data.crestsystems.ai/data/wallet/:addressWhen to prefer
Use this endpoint when you need a rich, multi-dimensional behavioral profile of a specific EVM wallet's agent-commerce activity on Base mainnet, especially for risk assessment, whale identification, or understanding x402 payment patterns. Prefer this over generic on-chain data tools when you need pre-computed behavioral clusters and composite scoring across 18,000+ wallets rather than raw transaction data.
Side effects
- Wallet address not found in dataset — returns empty profile or 404 if wallet has no x402 activity
- Invalid address format — returns 400 bad request for malformed hex addresses
- Wallet has insufficient activity — may return low-confidence scores or sparse profile
- Rate limiting or payment failure — returns 402 if USDC payment not completed
- Network or upstream data unavailability — returns 503 or partial data
