How this service works
ERC-20 balanceOf for a holder on Base mainnet for $0.001 USDC via eth_call. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.
Output
Returns the raw ERC-20 balanceOf result for the specified holder and token contract on Base mainnet, reflecting the on-chain token amount as returned by the eth_call. Typically includes the balance as a numeric value (likely in the token's smallest unit, e.g. wei-equivalent).
Example use cases
DeFi eligibility gate check
“Before letting this user claim rewards, check if wallet 0xAbC...123 holds at least 100 units of the governance token at contract 0xDef...456 on Base mainnet.”
Portfolio balance snapshot
“Pull the current on-chain balance of the USDC token at 0xA0b86991... for my wallet 0x742d35Cc... on Base mainnet so I can update my portfolio dashboard.”
Airdrop recipient verification
“I need to verify that address 0x1234...abcd actually holds our airdropped token at contract 0x9876...efgh on Base before I process their support ticket — can you check the balance?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/base-token-balanceWhen to prefer
Choose this endpoint when you need a quick, pay-per-call on-chain ERC-20 balance lookup on Base mainnet without managing your own RPC node or API keys. It is ideal for agents that need to gate actions on token holdings, verify balances before transactions, or enrich user profiles with live on-chain data on Base L2, especially in x402-compatible payment flows.
Side effects
- Invalid or malformed wallet address returns an error or zero balance
- Invalid token contract address (not an ERC-20) may return an error or empty result
- Network issues with Base mainnet RPC may cause timeouts
- Payment failure via x402 prevents the call from executing
- Non-Base contract addresses (e.g. Ethereum mainnet) will return incorrect or no results
