“Pull the current ERC20 token balances for wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 across all major EVM chains and show me the full token list with amounts.”
Technical details
Endpoint
POSThttps://wallet-portfolio-history-mcp.mtree.workers.dev/tools/token_balancesWhen to prefer
Choose this endpoint when you need a curated, multi-chain ERC20 token balance snapshot for a specific wallet — especially when historical comparison, source provenance, or coverage metadata is important. Prefer this over raw on-chain RPC calls when you need normalized, enriched data ready for downstream wallet diligence or risk analysis workflows.
Side effects
- Invalid or malformed wallet address returns an error response
- Unsupported chain yields empty or partial results
- Payment failure (x402 USDC not authorized) blocks the request
- Wallet with no ERC20 activity returns empty token list
- D1 snapshot stale or unavailable may return outdated balances
