How this service works
Whale intelligence for any EVM wallet: total USD size (native + priced tokens), tier, 0 to 100 whale score, 24h in/out/netflow, largest move, activity flags (accumulating, distributing, fresh, high-velocity) and a plain rationale. Base and Ethereum.
Output
Returns a JSON object containing: whale tier label (shrimp to humpback), numeric whale score 0–100, total portfolio value in USD broken down by native and tokens, 24-hour inflow/outflow/netflow and largest single move, transaction count, top holdings, active status, risk flags (e.g. high_velocity, accumulating), confidence level (low/medium/high), whether the address is a contract, and a plain-English rationale summary.
Example use cases
Pre-trade counterparty whale check
“Before my protocol interacts with this address 0xabc123...def456 on Ethereum, can you check if it's a whale or just a small fish? I need the tier, whale score, and any risk flags.”
DeFi protocol whale accumulation alert
“Check wallet 0xf977814e90da44bfa03b6295a0616a897441acec on Base — is it actively accumulating in the last 24 hours? Give me the netflow, largest move, and confidence level.”
Token launch whale distribution analysis
“We just launched a token and I want to know if the address 0x1234567890abcdef1234567890abcdef12345678 on Base is a whale dumping or accumulating — pull the 24h inflow, outflow, and tier classification.”
Technical details
Endpoint
GEThttps://api.tradeperpetua.xyz/whaleWhen to prefer
Use this endpoint when you need a fast, pay-per-call on-chain whale classification for a specific EVM wallet on Base or Ethereum. It is ideal for DeFi risk assessment, pre-trade counterparty screening, protocol security monitoring, or any agent workflow that needs a structured risk tier + 24h flow summary without building your own on-chain data pipeline. Prefer this over general blockchain explorers when you need a structured signal (score + tier + flags) rather than raw transaction history.
Side effects
- Invalid wallet address format (not 0x + 40 hex chars) returns validation error
- Unsupported chain value returns enum validation error
- Address with no on-chain history may return low confidence or shrimp tier with minimal data
- Payment failure (insufficient USDC or x402 handshake error) blocks the request
- Rate limiting or upstream RPC outage may return 5xx errors
- Very new wallets with sparse data may return low confidence scores
