Technical details

Endpoint

GEThttps://origin-mcp.fly.dev/mcp/tools/basescan_wallet_balance?utm_source=zero.xyz

When to prefer

Use this endpoint when you need a complete snapshot of both ETH and ERC-20 token holdings for a specific wallet on the Base network. Prefer this over general blockchain RPCs when you need human-readable token data with symbols and amounts in one call.

Side effects

Invalid or malformed wallet address returns an error
Address with no activity may return zero balances
Rate limiting or upstream Basescan API unavailability
Network-specific errors if querying non-Base addresses
Payment failure due to insufficient USDC for the $0.001 fee
