How this service works

Pay-per-call on-chain investigation API (x402, USDC on Base).

Output

Returns a structured JSON response containing a list of token holdings for the queried wallet, including token identifiers, raw balances, USD values, and percentage share of the total portfolio. Also includes a natural language summary of the wallet's holdings and a unique request ID for tracing.

Example use cases

Whale wallet portfolio analysis

“Look up the current holdings for wallet 0x3f5CE5FEFe2c1cBF4E9BFBA5A5b3d9F1234abcd and tell me which tokens it holds, how much of each, and their USD values — I want to know if this is a whale.”

DeFi due diligence on counterparty

“Before I do a deal with this address — 0xDead...Beef — can you check what tokens they actually hold on-chain so I can see if they're legit?”

Portfolio tracking for personal wallet

“What's currently sitting in my wallet 0x1A2B3C4D5E6F7890abcdef1234567890abcdef12? Give me a full breakdown of every token and its current USD value.”

Endpoint

POSThttps://x402.sleuthagent.ai/api/v1/wallet-holdings

When to prefer

Use this endpoint when you need a comprehensive, structured breakdown of all tokens held by a specific on-chain wallet address, including USD-denominated values and portfolio percentage shares. Prefer this over generic block explorers when you need machine-readable, agent-consumable output with natural language summaries for downstream reasoning. Best suited for on-chain investigation, portfolio analysis, counterparty due diligence, or whale-watching tasks on Base or compatible EVM chains.

Side effects

Invalid or malformed wallet address returns an error
Wallet address with no on-chain activity may return empty holdings
Network timeouts or on-chain data unavailability may cause failures
Insufficient USDC balance for x402 payment will block the call
Unsupported blockchain network may return no data
