Output
Returns a JSON object containing the wallet_multichain_snapshot field with cross-chain balance and portfolio data, along with any warnings about data quality or coverage, a status field indicating success, and a full receipt with payment ID, execution ID, request ID, latency, network, and a SHA-256 hash of the result for verification.
Example use cases
Portfolio overview across chains
“Give me a full multichain snapshot of my wallet 0x742d35Cc6634C0532925a3b844Bc454e4438f44e — I want to see everything it holds across all blockchains.”
DeFi audit before a trade
“Before I make this trade, can you snapshot wallet 0xdAC17F958D2ee523a2206206994597C13D831ec7 across all chains so I can see exactly what assets are available?”
Investigative wallet research
“I need to know what a specific wallet holds across every blockchain — can you run a multichain snapshot on 0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe and give me all the details?”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/wallet_multichain_snapshot/invokeWhen to prefer
Choose this endpoint when you need a unified, cross-chain view of a wallet's holdings in a single API call rather than querying each blockchain individually. It is ideal for portfolio aggregation, pre-trade audits, or investigative research where multichain coverage matters. At $0.01 USDC per call it is cost-effective for spot checks and agent workflows that need wallet snapshots without managing multiple chain-specific APIs.
Side effects
- Invalid or malformed wallet address returns an error or empty snapshot
- Unsupported chain or network results in missing data with a warning
- Payment failure via x402 protocol blocks execution
- Rate limiting or service unavailability returns a failed status
- Wallet with no activity may return an empty but valid snapshot with warnings
